摘要

最近，开发一种可在高温、极低温或高真空等恶劣条件下使用的新型滑动触点已成为迫切需要。本研究主要考察了三种具有导电性和机械刚度的自润滑复合材料的接触阻力和摩擦系数。结果表明，固体润滑剂用量最少的复合材料(CMML-1) (WS/ sub2 /，石墨)的接触阻力和摩擦系数均较低，波动较小。通过EPMA分析，表明了锡对导电性能的贡献。

Low-speed sliding test characteristic of sliding contact containing solid lubricants for use under severe application conditions

Development of a new sliding contact, usable under severe conditions such as high temperature, extremely low temperature or high vacuum, has recently become an urgent necessity. This research mainly examines the contact resistance and coefficient of friction of three kinds of self-lubricating composite materials with electrical conductivity and mechanical stiffness. The result showed that a composite material (CMML-1) containing the lowest quantity of solid lubricants (WS/sub 2/, graphite) was low in both contact resistance and coefficient of friction and lower in fluctuation. By EPMA analysis, the Sn contribution to electrical conductivity was suggested.
