本文介绍了我国粉末冶金制品在汽车和农机上的应用概况,并对如何进一步发展汽车和农机用粉末冶金制品提出了建议。我国粉末冶金制品大约有65%用于汽车和农机工业。每辆汽车和拖拉机上一般采用3～5公斤粉末冶金制品,其中衬套类零件居多。粉末冶金工业必须适应汽车和农机工业大发展的形势,扩大应用,开发新产品,特别是高强度,高精度,复杂形状的结构零件。 This paper introduces the application of powder metallurgy products in automobiles and agricultural machinery in China, and puts forward suggestions on how to further develop powder metallurgy products for automobiles and agricultural machinery. About 65% of China’s powder metallurgy products are used in the automobile and agricultural machinery industries. Each car and tractor on the general use of 3 to 5 kg of powder metallurgy products, including the majority of bushings. Powder metallurgy industry must adapt to the situation of large-scale development of automobile and agricultural machinery industry, expand the application, develop new products, especially high-strength, high-precision, complex shape of the structural parts.
