ABSTRACT:
A coating powder for relatively slideable parts consisting essentially of a mixture of about 80%-60% graphite and about 20%-40% of an unhardened epoxide-containing epoxy resin/hardener mixture. The coating powder is made by admixing an epoxy resin and a hardener to a uniform mixture at an elevated temperature at which the epoxy resin does not react with the hardener while in the molten state. The unhardened epoxy resin/hardener mixture is then ground into coarse particles and admixed with coarse particles of graphite and the mixture ground to a fine powder. The invention also includes machinery having at least one self-lubricated surface coated with said powder which has been heated after application to the surface to form a cross-linked thermoset polymer binding said graphite.
