本文从摩擦学观点出发,通过改变粉末冶金工艺,筛选出几种机械强度高、摩擦磨损性能优异、而且是电的良导体的银及其合金基自润滑复合材料,并举例说明该材料作为超高真空中的防冷焊滑动轴承和高温高真空中自润滑滚动轴承保持架材料以及大气与高真空中电接触材料的实用结果。 In this paper, from the tribological point of view, by changing the powder metallurgy process, screened several high mechanical strength, excellent friction and wear properties, and is a good conductor of silver and its alloy-based self-lubricating composite materials, and illustrates the material as a super Cold-proof welded bearings in high vacuum and self-lubricating rolling bearing cage materials in high temperature and high vacuum as well as practical results of electrical contact materials in the atmosphere and in high vacuum.
