Abstract
Abstract Slide assemblies, which each include a metallic member and a ceramic member to slide with the metallic member. The metallic member has a sliding surface coated with a mixture consisting essentially of a solid lubricant and a binder. The mixture of the solid lubricant and the binder is a combination selected from the group consisting of LiF+MoO 3 , PbO+Cu, MoS 2 +Cu, LiF+Ni--Cr--Mo--Si, and LiF+Co--Mo--Cr--Si. Silicon nitride, sialon, mullite, partially stabilized zirconia, or silicon carbide is preferably used as the ceramic member. The slide assemblies exhibit excellent high frictional resistance and wearing resistance even in dry condition at high temperatures.
