Peugeot is a major French car brand, part of PSA Peugeot Citroën. It is the second largest automaker in Europe, behind Volkswagen. Peugeot's roots go back to pepper, salt and coffee mill manufacturing in 1842 and later bicycle manufacturing at the end of the 19th century. Its world headquarters are in Paris, Avenue de la Grande Armée, close to Porte Maillot and the Concorde Lafayette Hotel but the Peugeot company and family is originally from Sochaux, France. Peugeot retains a large manufacturing plant in Sochaux which is also home to the Peugeot Museum. The company also sponsors the Sochaux football club, founded in 1928 by a member of the Peugeot family: the club' s arms contain a lion logo similar to Peugeot's.

The Peugeot family of Valentigney, Montbeliard, Franche-Comte, France, began manufacturing coffee grinders in the 1800s. Although the Peugeot factory had been in the manufacturing business since the 1700s,[1] the company's entry into the world of wheeled vehicles was by means of crinoline dresses, which used steel rods, leading to umbrella frames, wire wheels, and ultimately bicycles.[2] Armand Peugeot introduced his "Le Grand Bi" penny-farthing in 1882 and along with a range of other bicycles. Peugeot bicycles continued to be built until very recently, although the car company and bike company parted ways in 1926.

Armand Peugeot became interested in the automobile early on, and after meeting with Gottlieb Daimler and others, was convinced of its viability. The first Peugeot automobile (a three-wheeled steam-powered car designed by Léon Serpollet) was produced in 1889; only four were made.[3] Steam power was heavy and bulky and required lengthy warmup times. In 1890, after meeting Gottlieb Daimler and Emile Levassor, steam was abandoned in favour of a four-wheeled car with a petrol-fuelled internal combustion engine built by Panhard under Daimler licence. The car was more sophisticated than many of its contemporaries, with a three-point suspension and a sliding-gear transmission.[4]

More cars followed, twenty-nine being built in 1892, forty in 1894, seventy-two in 1895, 156 in 1898, and fully three hundred in 1899.[5] These early models were given "Type" numbers with the Type 12, for example, dating from 1895. Peugeot became the first manufacturer to fit rubber tires to a petrol-powered car that year (solid tires).[citation needed] Peugeot was also an early pioneer in motor racing, entering the 1894 Paris-Rouen Rally with five cars[6] (placing second, third {Pierre Giffard, who had conceived the trial}, and fifth {Koechlin})[4] and the 1895 Paris-Bordeaux with three, where they were beaten by Panhard's car[7] (despite an average speed of 20.8 km/h (12.9 mph)[8] and taking the 31,500 franc prize.[9] This also marked the debut of Michelin pneumatic tyres in racing,[10] also on a Peugeot; they proved insufficiently durable.[11] Nevertheless, the vehicles were still very much horseless carriages in appearance and were steered by a tiller.

1896 saw the first Peugeot engines built; no longer were they reliant on Daimler. Designed by Rigoulot, the first engine was an 8 hp (6.0 kW) horizontal twin fitted to the back of the Type 15.[10] It also served as the basis of a nearly exact copy produced by Rochet-Schneider.[10] Further improvements followed: the engine moved to the front on the Type 48 and was soon under a hood (bonnet) at the front of the car, instead of hidden underneath; the steering wheel was adopted on the Type 36; and they began to look more like the modern car.

In 1896 Armand Peugeot broke away from Les Fils de Peugeot Frères to form his own company, Société Anonyme des Automobiles Peugeot, building a new factory at Audincourt to focus entirely on cars.[10] In 1899, sales hit 300; total car sales for all of France that year were 1200.[10] The same year, Lemaitre won the Nice-Castellane-Nice Rally in a special 5,850 cc (357 cu in) 20 hp (14.9 kW) racer.[10]

At the 1901 Paris Salon, Peugeot debuted a tiny shaft-driven 652 cc (40 cu in) 5 hp (3.7 kW) one-cylinder, dubbed Bébé (Baby), and shed its conservative image, becoming a style leader.[12] After placing nineteenth in the 1902 Paris-Vienna rally with a 50 hp (37.3 kW) 11,322 cc (691 cu in) racer, and failing to finish with two similar cars, Peugeot quit racing.[12]

Peugeot added a motorcycle to its range in 1903, and motorcycles have been built under the Peugeot name ever since. By 1903, Peugeot produced half of the cars built in France, and they offered the 5 hp (4 kW) Bébé, a 6.5 hp (4.8 kW) four-seater, and an 8 hp (6.0 kW) and 12 hp (8.9 kW) resembling contemporary Mercedes models.[12]

The 1907 Salon showed Peugeot's first six-cylinder, and marked Tony Huber joining as engine builder.[12] By 1910, Peugeot's product line included a 1,149 cc (70 cu in) two-cylinder and six four-cylinders, of between 2 litres and 6 liters. In addition, a new factory opened the same year at Sochaux, which became the main plant in 1928.[13]

A more famous name, Ettore Bugatti, designed the new 850 cc (52 cu in) four-cylinder Bébé of 1912.[12] The same year, Peugeot returned to racing with a team of three driver-engineers (a breed typical of the pioneer period, exemplified by Enzo Ferrari among others): Jules Goux (graduate of Arts et Metiers, Paris), Paolo Zuccarelli (formerly of Hispano-Suiza), and Georges Boillot (collectively called Les Charlatans), with 26 year old Swiss engineer Ernest Henry to make their ideas reality. The company decided voiturette (light car) racing was not enough, and chose to try grandes épreuves (grand touring). They did so with an engineering tour de force: a DOHC 7.6 liter four cylinder (110x200 mm) with four valves per cylinder.[14] It proved faster than other cars of its time, and Boillot won the 1912 French Grand Prix at an average of 68.45 mph (110.2 km/h), despite losing third gear and taking a twenty minute pit stop.[15] In May 1913, Goux took one to Indianapolis, and won at an average of 75.92 mph (122.2 km/h), recording straightaway speeds of 93.5 mph (150.5 km/h).[16] In 1914, Boillot's 3 liter L5 set a new Indy lap record of 99.5 mph (160.1 km/h), and Duray placed second (beaten by ex-Peugeot ace Réné Thomas in a 6,235 cc (380 cu in) Delage).[17] Another (driven by Boillot's brother, André) placed in 1915; similar models won in 1916 (Dario Resta) and 1919 (Howdy Wilcox).

For the 1913 French Grand Prix, an improved L5 (with 5,655 cc (345 cu in) engine) was produced with a pioneering ballbearing crankshaft, gear-driven camshafts, and dry sump lubrication, all of which soon became standard on racing cars; unfortunately, Zuccarelli was killed during testing on public roads,[18] but Boillot easily won the event, making him (and Peugeot) the race's first double winner.[19] For the 1914 French GP, Peugeot was overmatched by Mercedes, and despite a new innovation, four-wheel brakes (against the Benz's rear-only), Georges proved unable to match them and the car broke down.[20] (Surprisingly, a 1914 model turned a 103 mph (165.8 km/h) lap in practice at Indy in 1949, yet it failed to qualify.)[21] Peugeot was more fortunate in 1915, winning at the French GP and Vanderbilt Cup.[21]

During the First World War, Peugeot turned largely to arms production, becoming a major manufacturer of arms and military vehicles, from bicycles to tanks and shells.

[edit] Inter war years

Postwar, car production resumed in earnest.

Racing continued as well, with Boillot entering the 1919 Targa Florio in a 2.5 liter (150ci) car designed for an event pre-empted by World War One; the car had 200,000 km (124,000 mi) on it, yet Boillot won with an impressive drive (the best of his career)[21] Peugeots in his hands were third in the 1925 Targa, first in the 1922 and 1925 Coppa Florios, first in the 1923 and 1925 Touring Car Grands Prix, and first at the 1926 24 Heures du Spa.[21] Peugeot introduced a five valve per cylinder, triple overhead cam engine for the Grand Prix, conceived by Marcel Gremillon (who had criticised the early DOHC); but the engine was a failure.[21]

The same year, Peugeot debuted 10 hp (7.5 kW) and 14 hp (10.4 kW) fours, the larger based on the Type 153, and a 6 liter 25 hp (19 kW) sleeve valve six, as well as a new cyclecar, La Quadrilette.[21]

During the '20s, Peugeot expanded, in 1926 splitting the cycle (pedal and motor) business off to form Cycles Peugeot, the consistently profitable cycle division seeking to free itself from the rather more cyclical auto business, and taking over the defunct Bellanger and De Dion companies in 1927.[21] 1928 saw the introduction of the Type 183.

New for 1929 was the Type 201, the cheapest car on the French market,[21] and the first to use the later Peugeot trademark (and registered as such)—three digits with a central zero. The 201 would get independent front suspension in 1931,[22] the first mass-produced car to have it.[citation needed] Soon afterwards the Depression hit; Peugeot sales decreased but the company survived.

In 1933, attempting a revival of fortune, the company unveiled a new, aerodynamically styled range. In 1934 Peugeot introduced the 402BL Éclipse Décapotable, the first convertible with a retractable hardtop[23] — an idea followed later by the Ford Skyliner in the 1950s and revived in the modern era by the Mitsubishi 3000GT Spyder in 1995. More recently, many manufacturers have offered retractable hardtops, including Peugeot itself with the 206 cc.

Three interesting models of the thirties were the Type 202, Type 302 and Type 402. These cars had curvaceous bodies, with headlights behind sloping grille bars, evidently inspired by the Chrysler Airflow.[24] The 2.1 liter[24] 402 entered production in 1935 and was produced until the end of 1941, despite France's occupation by the Nazis. For 1936, there was the new Airflow-inspired 302 (which ran until 1938) and a 402-based large model, designed by Andrean, which featured a vertical fin and bumper, with the first high-mounted taillight.[24] The entry-level 202 was built in series from 1938-1942, and about 20 more examples were built from existing stocks of supplies in February 1945. The 202 lifted Peugeot's sales in 1939 to 52,796, just behind Citroën.[25] Regular production began again in mid-1946, and lasted into 1949.

[edit] Post World War II

In 1946,[25] the company restarted car production with the 202, delivering 14000 copies.[24] In 1947, Peugot introduced the Type 203, with coil springs, rack-and-pinion steering, and hydraulic brakes.[25] The 203 set new Peugeot sales records, remaining in production until 1960.[24]

Peugeot would take over Chenard-Walcker and buy a part of Hotchkiss in 1950,[25] then introduce a popular model in 1955: the Type 403. With a 1.5 liter engine, it sold one million copies by the end of its production run in 1962, [26]

The company began selling cars in the United States in 1958, and in 1960 introduced the Type 404, which used a 1,618 cc (99 cu in) version of the 403 engine, tilted 45o. The 404 proved rugged enough to win the East African Safari Rally, in four of the six years between 1963 and 1968.

More models followed, many styled by Pininfarina. Like many European manufacturers, collaboration with other firms increased; Peugeot worked with Renault from 1966 and Volvo from 1972.

[edit] Take over of Citroën and formation of PSA

In 1974 Peugeot bought a 30% share of Citroën, and took it over completely in 1975 after the French government gave large sums of money to the new company. Citroën was in financial trouble because it developed too many radical new models for its financial resources. Some of them, notably the Citroën SM and the Comotor rotary engine venture proved unprofitable. Others, the Citroën CX and Citroën GS for example, proved very successful in the marketplace.

The joint parent company became the PSA (Peugeot Société Anonyme) group, which aimed to keep separate identities for both the Peugeot and Citroën brands, while sharing engineering and technical resources. Peugeot thus briefly controlled the valuable racing brand name Maserati, but disposed of it in May 1975 out of short term financial concerns.[citation needed]

Both Citroën enthusiasts and automotive journalists point out that the company's innovation and flair took a marked downturn with the acquisition. The Citroën brand has continued to be successful in terms of sales, and now achieves over a million units annually.

[edit] Take over of Chrysler Europe

The group then took over the European division of Chrysler (which were formerly Rootes and Simca), in 1978 as the American auto manufacturer struggled to survive. Further investment was required because PSA decided to create a new brand for the entity, based on the Talbot sports car last seen in the 1950s. From then on, the whole Chrysler/Simca range was sold under the Talbot badge until production of Talbot-branded passenger cars was shelved in 1986.

The flagship of this short-lived brand was the Tagora, a direct competitor to PSA's 604 and CX models. This was a large, angular saloon based on Peugeot 505 mechanicals.

All of this investment caused serious financial problems for the entire PSA group; PSA lost money from 1980 to 1985. The Peugeot takeover of Chrysler Europe had seen the aging Chrysler Sunbeam, Horizon, Avenger and Alpine ranges rebranded as Talbots. There were also new Talbots in the early 1980s—the Solara (a saloon version of the Alpine hatchback), and the Samba (a small hatchback to replace the Sunbeam).

In 1983 Peugot launched the popular and successful Peugeot 205, which is largely credited for turning the company's fortunes around.[citation needed]

In 1984 PSA developed its first contacts with The People's Republic of China, resulting in the successful Dongfeng Peugeot-Citroën Automobile venture in Wuhan.

In 1986, the company dropped the Talbot brand for passenger cars when it ceased production of the Simca-based Horizon/Alpine/Solara models. What was to be called the Talbot Arizona became the 309, with the former Rootes plant in Ryton and Simca plant in Poissy being turned over for Peugeot assembly. Producing Peugots in Ryton was significant, as it signalled the very first time Peugeots would be built in Britain. The Talbot name survived for a little longer on commercial vehicles until 1992 before being shelved completely.

As experienced by other European volume car makers, Peugot's U.S. and Canadian sales faltered and finally became uneconomical, as the Peugeot 505 design aged. Several ideas to turn around sales in the United States, such as including the Peugeot 205 in its lineup, were considered but not pursued. In the early nineties, the newly introduced Peugeot 405 proved uncompetitive with domestic and import models in the same market segment, and sold less than 1,000 units. Total sales fell to 4,261 units in 1990 and 2,240 through July, 1991. This caused the company to cease U.S. And Canada operations after 33 years. There are currently no known plans to return to the American market.

Beginning in the late 1990s, with Jean-Martin Folz as president of PSA, the Peugeot-Citroën combination seems to have found a better balance. Savings in costs are no longer made to the detriment of style.

On April 18, 2006, PSA Peugeot Citroën announced the closure of the Ryton manufacturing facility in Coventry, England. This announcement resulted in the loss of 2,300 jobs as well as about 5,000 jobs in the supply chain. The plant produced its last Peugeot 206 on December 12, 2006 and finally closed down in January 2007.

Peugeot is developing a diesel-electric hybrid version of the Peugeot 307 that can reach 80 mpg.[clarify] It is a 2-door cabriolet and is currently only in the concept stages, but if it reaches production would be one of the more fuel efficient cars available.[citation needed]. Peugeot will make a new car in 2008 with the name Peugeot 407.

Peugeot was involved in motorsport from the earliest days and entered five cars for the Paris-Rouen Trials in 1894 with one of them, driven by Lemaitre, finishing second. These trials are usually regarded as the first motor sporting competition. Participation in a variety of events continued until World War I, but it was in 1912 that Peugeot made its most notable contribution to motor sporting history when one of their cars, driven by Georges Boillot, won the French Grand Prix at Dieppe. This revolutionary car was powered by a straight-4 engine designed by Ernest Henry under the guidance of the technically knowledgeable racing drivers Paul Zuccarelli and Georges Boillot. The design was very influential for racing engines as it featured for the first time DOHC and four valves per cylinder providing for high engine speeds, a radical departure from previous racing engines which relied on huge displacement for power. In 1913 Peugeots of similar design to the 1912 Grand Prix car won the French Grand Prix at Amiens and the Indianapolis 500. When one of the Peugeot racers remained in the United States during World War I and parts could not be acquired from France for the 1914 season, owner Bob Burma had it serviced in the shop of Harry Arminius Miller by a young mechanic named Fred Offenhauser. Their familiarity with the Peugeot engine was the basis of the famed Miller racing engine, which later developed into the Offenhauser, or "Offy" racing engine.

The company has had much success in international rallying, notably with the durable Peugeot 504, the four-wheel-drive turbo-charged versions of the Peugeot 205, and more recently the Peugeot 206. The 206 rally car had significant success in the rally championship, beating the Subaru Impreza, Ford Focus and Mitsubishi Lancer, cars which had traditionally dominated the sport. The 206 was retired practically unbeaten after several successful years, and replaced with the comparatively disappointing Peugeot 307 cc.

Throughout the mid-1990s, the Peugeot 406 saloon (called a sedan in some countries) contested touring car championships across the world, enjoying success in France, Germany and Australia, yet failing to win a single race in the British Touring Car Championship despite a number of podium finishes under the command of 1992 British Touring Car Champion Tim Harvey.

The British cars were prepared by Prodrive in 1996, when they sported a red livery, and by MSD in 1997-1998, when they wore a distinctive green and gold flame design. Initially the 406's lack of success was blamed on suspension problems, but it is now clear that the team was underfunded and the engine lacked power.[citation needed]

In 2001, Peugeot entered three 406 coupes into the British touring car championship to compete with the dominant Vauxhall Astra coupes. Unfortunately the 406 coupe was at the end of its product life-cycle and was not competitive, despite some promise towards the end of the year, notably when Peugeot's Steve Soper led a race only to suffer engine failure in the last few laps. The 406 coupes were retired at the end of the year and replaced with the Peugeot 307—again, uncompetitively—in 2002.

Peugeot won the Manufacturers title of the World Rally Championship in 1985 and 1986 with its 205 T16. Peugeot won the manufacturers championship again in 2000, 2001 and 2002 with the 206. Peugeot won the grueling Paris Dakar Rally each year from 1987 to 1990.

In the 1990s the company competed in the Le Mans 24 Hours race, winning in 1992 and 1993 with the 905. After early problems with reliability and aerodynamics, the 905 was also successful in the World Sportscar Championship, winning eight of the 14 races across the 1991 and 1992 seasons and winning the team and driver titles in 1992. Peugeot returned to sportscar racing and Le Mans in 2007, with the diesel-powered 908. Peugeot is also involved with the Courage C60 Le Mans racing team.

The company has also been involved in providing engines to Formula One teams, notably to McLaren in 1994, to Jordan for the 1995, 1996 and 1997 seasons, and to Prost for the 1998, 1999 and 2000 seasons. Peugeot's F1 interests were sold to Asiatech at the end of the 2000 season.

[edit] Peugeot model numbers


Peugeot chooses the names used on its models in the form x0y or x00y, where x describes the size of the car (and hence its class) and y describes the model number (the higher the number, the newer the model). Thus a Peugeot 406 is bigger and newer than a Peugeot 305. This rule has its exceptions: for instance the Peugeot 309 was produced before the Peugeot 306—the out-of-step number signified the 309's Talbot underpinnings rather than it coming from a Peugeot lineage. Variants are also excluded: the 206 SW, for example, is about the same length as a "40y" car.

This tradition began in 1929 with the launch of the 201, which followed the 190. All numbers from 101 to 909 have been deposited as trademarks. Although in 1963 Porsche was forced to change the name of its new 901 coupé to 911, certain Ferraris and Bristols have been allowed to keep their Peugeot-style model numbers. An unsubstantiated explanation for the central '0' is that on early models the number appeared on a plate on the front of the car, with the hole for the starting handle coinciding with the zero. More recently, on the 307 cc and the 607 the button to open the trunk is located in the '0' of the label.

For specific niche models such as minivans or SUVs, Peugeot is now using a four digit system, with a double zero in the middle. It was tested with the 4002 concept car. The 1007 used this system when it was launched in 2005, and the new Peugeot Crossover SUV is named 4007.

Peugeot has also announced that after the 9 series, it would start again with 1, producing new 201, 301 or 401.

Peugeot has produced three winners of the European Car of the Year award.

  鑽石是高貴豪華的裝飾品,鑲嵌天然鑽石的首飾是首飾之冠。可是,鑽石由於稀少而價格昂貴,尤其是稍大粒的 鑽石,一般人都不敢問津。於是,用廉價寶石、人造寶石甚至玻璃來代替或冒稱鑽石的活動就隱秘地或公開地愈演愈烈,假鑽石的生意也日益隆起來了。常見的形形 色色的假鑽石共有13種,現介紹7種如下:

(1)玻璃:
  用玻璃磨成的假鑽石很容易區別,因為它的折光率低,沒有真鑽石那種閃爍的彩色光芒,稍有經驗的人一看便知。另外,可用白瓷碗盛一碗清水,冒充鑽石的無 色玻璃製品漫入水中即看不清其輪廓,而真鑽石暗黑的輪廓在水中顯得十分清楚。

(2)人造尖晶石:
  它和鑽石的區別是,缺少閃爍的彩色光芒,將它浸入二碘甲烷中,也會輪廓模糊,而真鑽石的輪廓則十分清楚。

(3)水晶和黃玉:
  這兩種天然礦物的透明晶體,經琢磨後也有點像鑽石,但都缺少閃爍的彩色光芒。且它們都是“非均質體”,而鑽石是“均質體”,用偏光儀易於區分。

(4)人造藍寶石:
  無色透明的人造藍寶石在琢磨後也可作為鑽石的代用品。但它在“二碘甲烷”中幾乎消失不見,而真鑽石的邊緣暗黑,非常清楚。

(5)鋯石:
   在人造立方氧化鋯出現之前,鋯石是最佳的鑽石代用品。 鋯石具有很強的雙折射,即它有兩個折光率,並且兩個折光率之間的差別較大。由此而產生了一種很特殊的光學現象,當用放大鏡觀察琢磨好的鋯石棱面寶石時,由 其頂面可以看出底部的面和棱線有明顯的雙影。而鑽石因為是“均質體”,絕無雙影現象。

(6)人造金紅石:
   金紅石是一種普通的天然礦物,它的成分是二氧化鈦,由於它的折光率(2.61—2.90)比鑽石(2.42)還要高,故琢磨寶石後能出現明亮耀眼的閃 光,且能出現彩虹般的變化,顯得非常美麗。可惜的是,天然金紅石幾乎全是不透明的,所以1947年才經美國鉛業公司首先制出了人造金紅石。其中無色透明者 用作鑽石代用品或假冒品,其五彩繽紛的閃光超過了真鑽石,常被稱為“五彩鑽”或“五色鑽”。

  但由於金紅石有強烈的折光率,故與鋯石一樣,能用放大鏡從頂面看到底部棱線的顯著的雙影,故易與鑽石區別。此外,“五彩鑽”因閃光過分豔麗,並帶有不清澈的乳白光,故有庸俗之感,遠不如鑽石閃光的高雅可愛。

(7)立方氧化鋯:
   (即“蘇聯鑽”):這是首先由原蘇聯推出的最理想的鑽石代用品或冒充品,是人造化合物,無天然礦物。自從立方氧化鋯問世後,其他多種人造寶石原料,都 只用作別的中低檔寶石代用品,而不再來磨制假鑽石了。這是由於立方氧化鋯在折光率、色散等方面與天然鑽石很接近。但它的硬度較低(8.5),比重為鑽石的 1.6—1.7倍,達5.6—6,且導熱性遠低於鑽石,故仍可用儀器準確地將其與鑽石區分開來。

鋯石〈Zircon〉

成份:矽酸鋯 ; 硬度:7.5 ; 比重:4.69 ; 折射率:1.93-1.98 ; 雙折射:0.059
產地:斯里蘭卡、緬甸、泰國、高棉、越南、澳洲、巴西、奈及利亞、坦尚尼亞和法國。

   鋯石(Zircon)以無色最著名,因為極像鑽石,一直有意無意地被當成鑽石。儘管質純的鋯石是無色的,雜質卻可產生黃、橙、藍、紅、棕及綠色等變種。 產於泰國、越南和高棉的棕色寶石經過熱處理,可以變成受青睞的無色或藍色寶石。變回棕色的藍鋯石再重新加熱又可變成藍色。在氧氣中重新加熱的藍鋯石則會變 成金黃色。有別於鑽石的地方在於具有雙折射現象,並可從刻面邊緣的磨損情況鑑別。有些鋯石具有放射性的釷和鈾,會使晶體結構分解;衰變的鋯石稱為「低質」 鋯石,帶有「輻射變晶」結構;沒有受損的則稱為「高質」鋯石。

摩星鑽〈莫桑寶石〉

   其摩星鑽全名為 Synthetic Moissanite〈合成碳矽石〉,其化學成份為SIC〈碳化矽〉,由美國C3公司研發的鑽石替代品,它的硬度與閃亮的高色散,與天然鑽石很像,並優於 任何一種鑽石替代品〈如蘇聯鑽〉更重要的是,摩星鑽〈合成碳化矽〉對鑽石導熱儀的測試反應竟與天然鑽石無異!

  對於只以鑽石導熱儀來分辨鑽石真假的人來說,正是一種警訊,摩星鑽剛出現時,確有許多人因此受騙上當。

↑雷射號碼示意圖

   右圖是GIA DIAMOND REPORT 全貌,俗稱"大證",另一種GIA DIAMOND DOSSIER俗稱"小證",現在GIA將1克拉以上的鑽石打大證,以下則用小證,大證有鑽石的淨度圖,小證沒有,其他的條件都一樣。GIA證書曾經做過 改版,右圖是新版證書。


各部分所代表的意義 :
1.報告書簽發的日期
通常越新的日期越好,除非很久以前的日期,不然對鑽石價格影響不大。有些促銷用的鑽石會用日期較久以前的鑽石,有的甚至超過兩三年前。

2.Laser Inscription Registry雷射證書編號
格式:GIA XXXXXXXX。利用雷射技術在鑽石的腰圍上刻上證書的編號,雷射刻字服務要額外收費,有刻字的鑽石成本較高。鑽石是否要將證號刻上業界仍有爭議。

3.Shape and Cutting Style形狀和切磨型式
格式:XXXX XXXXX。描述鑽石的形狀和切磨型式,第一個字代表形狀〈圓形ROUND,梨形PEARS,心形HEARTS...等〉,第二個字是切磨型式〈通常是 BRILLIANT明亮式〉。同等級的鑽石圓形最貴,其他形狀會比圓形低。

4.Measurements尺寸
格式:XXX-XXX*XXXmm。第一個數字代表最短寬度,第二個數字代表最長寬度,第三個數字代表高度,單位是mm,精準到小數點以下2位。以圓形來 說,第一二個數字差距越小,鑽石就越圓,花式車工各有其比例值。

5.Weight重量
鑽石的重量,單位是克拉,精確到小數點以下2位。

6.Depth深度比例。
公式:高度/(最長寬+最短寬的平均值)*100%,59%~62%之間為佳。

7.Table桌面比例。
公式:桌面寬度/(最長寬+最短寬的平均值)*100%,55%~60%之間為佳。

8.Girdle腰圍寬度。
格 式:XXXX TO XXXX。描述最窄的腰圍到最寬的腰圍寬度,共分7級,MEDIUM為佳,不要太薄或太厚,跨兩級以內都可以接受,例如THIN TO MEDIUM,單一個級數〈如THIN〉表示鑽石的腰圍厚薄一致,如果又被評為MEDIUM則很優秀也少見。另外如果腰圍有刻面則會加上FACETED這 個評語。腰圍的評價有時候會影響價格甚巨,尤其是太厚的腰圍。

6.7.8 .三項常常會影響鑽石價格甚多,但是消費者卻常常忽略。跟同淨度成色的鑽石比較以為買到便宜的鑽石,但是價格便宜的原因往往來自這三項。

9.Culet尖底。
說明有無尖底。沒有的話寫NONE,有尖底則寫出尖底大小。最好不要有尖底,very small尚可接受。

10.Polish拋光。
修飾〈Finish〉的兩個要項之一。主要是用來評價鑽石的表面磨光等級。


11.Symmetry對稱。
修飾〈Finish〉的兩個要項之一。主要是用來評價鑽石刻面是否對稱良好大小一致,對稱的評等要得好的評價往往比拋光難。

10.11兩項是除了淨度成色以外影響鑽石價格最明顯且重要的兩個因素,也就是"車工條件"。

12.Clarity Grade淨度等級。
說明鑽石的淨度。

13.Color Grade成色等級。
說明鑽石的成色。

14.Fluorescence螢光反應。
說明鑽石是否有螢光反應。沒有寫NONE,有則把螢光反應的強弱及螢光顏色寫下,例如MEDIUM BLUE中等藍色螢光,只有天然的鑽石才會有螢光反應。有螢光反應的鑽石通常價格偏低,如果螢光強到"STRONG"或是"VERY STRONG"則價格可能降1%~2%,不過需要看是否會影響鑽石的透明度。這個項目也是大家常忽略的地方。

15.Comments評語。
鑑定師有其他需要補充說明的地方寫在這裡,所提到的項目通常並非重要到足以影響鑽石的各部評價,但是還是需要指出,都沒有需要補充寫NONE。

16.Additional Inscription額外刻字。
除了雷射證號以外的雷射刻字寫於此處。

17.淨度圖。
只有大證才有。鑑定師將影響淨度的特徵繪於圖上,成為這顆鑽石獨一無二的"指紋圖",日後其他鑑定師要看是否為同一顆鑽石便可以"按圖索驥"。購買鑽石的 時候,如果有多顆可以比較〈同淨度〉,則淨度特徵在底部比在正面好,在邊緣比在中間好。

18.KEY TO SYMBOLS淨度符號。
淨度圖中各種淨度特徵的代號。綠色表示該淨度特徵在鑽石表面,紅色表示該淨度特徵在鑽石中,黑色代表鑽石有額外的刻面。

19.GIA CLARITY SCALE GIA淨度分級表。

20.GIA COLOR SCALE GIA成色分級表。

21.雷射防偽標誌。

22.警語。

23.鑽石報告書流水編號。國際鑽石認證鑑定書

   國際鑽石証書都是由1~3位獨立珠寶鑑定師對鑽石詳細檢驗後,由獨立協會所發出之品質紀錄,紀錄著鑽石之色澤、淨度、重量及量度尺寸等。並用圖解將鑽石 之特徵表達出 來。鑽石証書就像我們的身份証可以避免與其他鑽石混淆,因鑽石不會有相同之特徵,鑽石証書只是用作品質鑑定証明,並非用作估值之用。

  目前世界各國有很多寶石鑑証所設立,並發出鑽石品質証明書,但只有少數能獲得消費者及業內人仕充份信任,其中市場上常見之鑽石評級証書,有〈IGI〉國際寶石研究所、〈EGL〉歐洲寶石研究所及〈GIA〉美國寶石研究所發出之証書普遍較受歡迎。

   但全世界具有公信力的國際知名鑑定所其實共有4 個,如IGI其鑑定的標準等同於GIA,在歐洲地區流通的程度比GIA還要更普遍,IGI更是鑽石雷射腰圍的首創者,GIA才隨後跟進,另以鑑定車工為主 的美國寶石協會AGS,還有比利時的鑽石高等評議會HRD,在全世界都具公信力。其鑽石鑑定機構成立年代:最早1931年美國寶石學院〈GIA〉、 1934年美國寶石協會〈AGS〉、1973年歐洲比利時的鑽石高等評議會〈HRD〉、1975年比利時的國際寶石學院〈IGI〉。

   對於投資者來說,到拍賣會上投資鑽石,還需要關注拍賣行提供的鑽石鑑定證書。從目前拍賣市場來看,「美國珠寶學院」〈Gemological Institute of America簡稱GIA〉與比利時的「鑽石高階議會」〈Hoge Read Voor Diamant簡稱HRD〉他們的公信力,可說是執全世界鑑證機構之牛耳, 他們為鑽飾、 寶石市場提供公正毫無偏坦之分級鑑證服務。世界頂級的蘇富比與佳士得兩大拍賣場皆參考並使用GIA及HRD之鑑定報告書進行議價。目前各地進行鑽石拍賣的 一些拍賣行也逐漸開始使用這些證書作為權威標準,因此投資者應該對此加以關注,也較有投資跟品質保證。

 鑽石是以4個「C」來分級,也就是「淨度」、「色澤」、「切工」和「克拉」。這4項分級決定了鑽石的價格。

一、淨度(Clarity):
  指的是鑽石的清澈度或純度。而這是由內含物的多寡、體積、本質與位置,還有鑽面是否有瑕疵所決定。

二、色澤(Color) :
  意味的是鑽石所含的色度。而鑽石的顏色範圍很廣,由無色、淡黃色、灰色至黃褐色。此外,還有深黃色、棕色、藍色、綠色、粉紅色到紅色。由於這些特別的顏色十分罕見,因此比較值錢。

三、切工 (Cut) :
  指的是切割鑽石瓣面排列的比例、角度、勻稱度與琢磨度。這些因素均足以增添鑽石的火光和亮度。

四、克拉 (Carat Weight):
  是鑽石的重量單位。1克拉為100分,相當於0.2公克。鑽石的克拉數愈大,價值也愈高。

如何以4C分辨鑽石的好壞?

Clarity 淨度 :
   鑽石的淨度取決於內含物的大小、色重及數量多寡,GIA鑑定鑽石的淨度是以10倍放大鏡下檢視時,FL、IF內外部之內含物不可見,VVS1、 VVS2內外部之內含物極難見,VS1、VS2內外部之內含物不易見,SI1、SI2內外部之內含物可見,I1、I2、I3內外部之內含物肉眼可見。

Color 顏色 :
  鑽石如同高硬度的玻璃,顏色愈白愈能讓光線通過,以高透明度產生閃耀的效果,因此以往鑑定的標準都是顏色愈白價格愈高,除了黃金鑽外,顏色愈黃價格愈 低,其標準則由GIA這類鑑定機構製定。

   GIA鑑定鑽石的顏色自D~O有12格,但約略分為D~E無色、F~G接近無色,H~J略黃、K~M帶黃,國外市場一般接受GIA標準的I、J等級,台灣則因為保值觀念較高,D~F等級需求量較大,事實上只要是個人喜好,什麼等級都好。

Cut 車工 :
   車工原指切磨鑽石形狀的工藝技術,現在還包括了鑽石的角度及比例。早期的鑽石切割著重於保有重量,工具也較原始,因此比例並不十分對稱,拋磨效果也有 限,光芒常常無法顯現 ; 現代的車工因有精密儀器的幫助,切割前可以計算出各種最具利潤及光芒的切割角度,拋磨技術也高,所以現代車工的鑽石光芒較以前勝上許多。

  在探礦技術大幅提昇後,鑽石產量豐富,於是各種花式車工一一展現,如邱比特車工或是完美車工,這類鑽石的價格年年上揚,不但可促銷鑽石,也提昇了鑽石的質感。

Carat 重量 :
  鑽石以卡(克拉)為單位,每卡為100分,而克拉這種計算單位的源由,是因為早期並沒有專屬於鑽石的微量單位,而豆類中克拉豆的特性,是任何一顆克拉 豆的重量都是一樣,即差異為難以計量之微,對於世界各地奔走的鑽石商人來說,方便又精準因而入選。

   鑽石並不是單以卡數計價,國際標準的Rapaport將4C皆列入計價標準,報表會隨世界性的通貨指數作調整,因此能確保鑽石的價格年年都能微幅上漲, 通常一克拉以上的鑽石較有收藏及保值效果。

全 球鑽石業者也在二○○○年成立「世界鑽石協會」,二○○二年十一月和各主要鑽石生產國達成協議, 為此,聯合國曾經通過兩個相關決議案,國際間並於二○○三年建立 制定「金伯利流程認證計畫」,做為未琢磨鑽石的產地認證機制,參加這個認證機制的鑽石業上下游國家共有七十二國,參與國同意,禁止處理與買賣未獲認證的鑽 石原石,希望藉此切斷血腥鑽石輸出的管道,確保唯有「非衝突鑽石」才能進入合法交易市場,政府會對每一筆合法未琢磨鑽石的出口會簽發證明並有紀錄。參與這 項管制機制的除了政府,還包括從生產、運銷、加工琢磨到零售的鑽石業者,以及相關的非政府組織。

   在南非、納米比亞及波札那,鑽石開採業已工業化,管理已上軌道;而獅子山、賴比瑞亞及民主剛果卻可能仍是在河床上淘鑽石,當局就很難有效管理。金伯利機 制對於這些國家的情況就特別注意,主要的監督工作是由鄰國間相互監看,任何國家若違反金伯利機制交易規定就會被制裁,禁止和參與金伯利機制的國家交易。由 於主要的鑽石進口國家,包括比利時、荷蘭及印度等鑽石加工業重鎮及最大的消費市場如美國,都加入了金伯利機制,制裁行動有相當的遏阻效力。

   然而金伯利流程當然不可能滴水不漏,畢竟鑽石極容易走私出境,而且一旦經過加工就無法判定產地。然而從統計數字來看,血鑽石在極盛時期佔全球產量約 4%,但二○○四年迄今已不到1%,顯見金伯利流程的確發揮了效用。

   即使如此,以數百億美元的鑽石交易來說,1%仍可換來不計其數的殺人武器。而且金伯利機制難免漏洞,聯合國10月份的報告顯示,有2,300萬美元衝突 鑽石由迦納、馬利等國流入合法市場,象牙海岸、馬利叛軍盤據地區繼續出口血鑽石,剛果也還在打鑽礦控制權爭奪戰,其實 市場上仍然充斥的沒有證書的鑽石,卻可能都是未經過流程流出的黑市血鑽石。世界鑽石產地

South Africa 南非 1869年發現第一顆鑽石。
Congo Republic (Zaire) 非洲剛果 占世界鑽石出產量二成。
Botswana 非洲波紮那 第三大鑽石礦。
Namibia 非洲那米比亞 1906年發現第一顆鑽石。
Brazil & Venezuela 巴西、委內瑞拉 在1725年發現鑽石。
India 印度 發現過好多出名鑽石如 Koh-i-Noor, the Orlov, the Hope, 和 the Sancy
Russia 蘇聯 1970年成為世界上第三大出產國。

世界鑽石中心與鑽石產地地圖
澳洲發現世界級大鑽礦,阿蓋爾鑽礦
在非洲波札那金利柏利管狀岩脈中,採礦作業的情形
鑽石沖積礦,當地人在河邊採礦作業的情形

  鑽 石的形成是在地底裡數百公里深處的地質層經原始碳受熱、壓力溶融結晶而成,大部份鑽石原生礦附著於雲母橄欖岩中,在億年前經由地殼板塊變動、火山爆發,隨 岩漿噴出帶到地表淺層下,其化學成份是 C碳元素,當然偶而會參雜其他元素如鐵、鉻、鎂等上萬種礦物,即俗稱內含物或雜質,內含物愈少就是純淨度愈高愈沒有瑕疵。

   而據文獻記載鑽石最早發現於印度而後巴西,鑽石的產地現今發現的分佈於南非、剛果、安哥拉、蘇聯…等二十幾國,特別集中於非洲。其開採過程是非常艱難費 時,而產量更是稀少,礦區挖掘每百噸礦物始能發現大小不等的一克拉原石,可見經琢磨好的一克拉以上鑽石是非常昂貴稀有的。而每一礦區的原石品質好壞都有, 並非那個礦區特別好或特別壞,因為鑽石結晶過程是完全相同的,連科學家都很難分辨出不同的產地有何差異性。

   由於鑽石的昂貴與稀有,科學家試圖在壓力維持6000度左右,大氣壓溫度1000℃左右的情況下,成功研發出人工鑽石與天然鑽石的特性,幾乎相同,但是 由於研發成本過高甚至高過天然鑽石的開採費用,以致目前並沒有量產。現今市場上有許多不同種類的人工鑽石均可輕易分辨出來。

鑽石的地質環境:
  鑽石被發現於原生礦床 (Primary Deposits)和次生礦床(Secondary Deposits)。大致上都是由火山爆發將鑽石原石伴隨火山熔液而噴出地表,因此形成管狀脈(Pipe Mine)。一般而言,沖積礦床所擷取之鑽石與管狀脈中之鑽石品質作比較,前者由於已經受過大自然的風雨河川沖洗,可得到較高比率的珠寶等級之寶石。

鑽石的形成過程:
  鑽石大約形成在地層80公里到200公里處,溫度約 1,100 -1,300℃,且必須同時具備壓力在 70,000㎏/1立方公分及碳(Carbon)元素存在之條件下,才可能形成鑽石,若有一項條件有所差異或缺乏時,則只能形成石墨。

現在、ネジを使用して上下させる機構を設計中です。
そこで、設計が止まってしまったのが、ねじの強度
(主に磨耗について)の妥当性が分からないという
事です。
現在、SUS304のナットとS45Cの硬質クロムメッキの
ボルトを使用する予定です。
ネジサイズはM8×P0.5です。
どなたか、参考になる資料等教えて頂けないで
しょうか?



ネジにかかる面圧はkg/mm2いくら位でしょうか?
10kgf/mm2で首記サイズのネジで100万サイクル程度可能なグリース扱ってます。



はじめまして
なぜ、最初に磨耗が起こるのかを考えればわかることだと思いますが、要するに摩擦力は面圧と摩擦係数から決まりますよね。ということはこれはネジの問題ではなく、単なる面と面の接触の問題となります。
磨耗について調べるにはバウデン・テーバーの「固体の摩擦と潤滑」が名著です(大学の図書館にあります。今は絶版かもしれません)。
あと、ネジで上下させる機構を設計とのことですが、台形ネジやボールネジを選択しなかった理由は単にコストの問題なのでしょうか?ちょっと気になりましたので・・・
