粉末冶金技术从广义上说就是以粉末为原料,经压缩成形和烧结而制造成品或半成品的技术。原料是金属、陶瓷及金属陶瓷等粉末。生产零件的需要领域相当广泛,其中汽车部件占需求的80％以上,除了汽车以外还包括家电产品、办公机器、农业机械、精密机器和缝纫机等。日本最近10年虽然汽车的产量没怎么发展,但烧结零件却增加了约2倍。现在每台汽车的使用量已为6.7Kg。而美国在1994年已超过12kg,欧洲在1993年为4.7kg。理论上说该数字可达到14kg。从有关日美欧的这些数字中可知
Powder metallurgy technology in a broad sense is the powder as raw material, compression molding and sintering and manufacturing finished or semi-finished products technology. Raw materials are metal, ceramic and metal powder and other ceramics. The production of parts requires a wide range of areas, of which automotive components account for more than 80% of demand, in addition to the car also includes home appliances, office machines, agricultural machinery, precision machinery and sewing machines. Although the production of automobiles in Japan has not progressed much in the last 10 years, sintered parts have increased by about 2 times. Now the use of each car has been 6.7Kg. While the United States already exceeded 12 kg in 1994 and Europe in 1993 to 4.7 kg. In theory, the figure can reach 14kg. From these figures on Japan, the United States and Europe we can see
