粉末冶金技术的发展历来与汽车工业的发展密切相关,汽车中用粉末冶金另件总重量一般占全部粉末冶金铁基制品产量的60％以上。美国在第二次世界大战前的粉末冶金技术发展初期,就开始在汽车中使用粉末冶金技术烧结青铜基含油轴承等,随后逐渐发展到采用铁基结构另件。日本在1974年～1980年期间汽车产量增加1.6倍,而粉末冶金烧结机械另件增加3倍。粉末冶金不断以自己的新材料、新产品、新工艺和新技术服务于汽车工业;同样,汽车工业的进步和发展,也有力地促进了粉末冶金技术的进步,并推动粉
The development of powder metallurgical technology has always been closely related to the development of the automobile industry. The total weight of the other parts used in automobiles generally accounts for more than 60% of the total output of iron-based powder metallurgy products. Early in the development of powder metallurgy technology before the Second World War, the United States started to use powder metallurgy to sinter bronze-based oil-bearing in automobiles, and then gradually developed to adopt iron-based structural components. Japan’s vehicle production increased 1.6 times between 1974 and 1980, while powder metallurgy sintering machinery increased another 3 times. Powder Metallurgy continues to serve the automobile industry with its new materials, new products, new processes and new technologies. Similarly, the progress and development of the automobile industry have also contributed to the advancement of powder metallurgy technology and promoted the development of powder
