汽车用粉末冶金轴承的研究日本Ｒ＆Ｄ股份有限公司进行了采用粉末冶金复合材料以压铸工艺生产汽车用轴承的研究。这种粉末冶金复合材料具有很好的机械性能和耐磨性，它含有３％～５％的铝，含石墨添加剂０．５％～３％。为了避免压铸件的复合材料因受热而引起硬度的降低，...
Automotive powder metallurgy bearing research R & D Co., Ltd. Japan conducted a powder metallurgy composite materials using die-casting process for the production of automotive bearings. The powder metallurgy composite material has good mechanical properties and wear resistance, it contains 3% ~ 5% of aluminum, graphite containing additives 0.5% ~ 3%. In order to avoid die-casting composite materials due to heat caused by the decrease of hardness, ...
