Abstract :
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 (WS2, 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
