    Abstract: A solid film lubricant system for protecting metal wear interfaces subject to high temperatures and wet lubrications, comprising an oil-attracting solid lubricant mixture with at least two elements selected from the group of graphite, MoS.sub.2 and BN; a support (i.e., hard lands or hard sublayer) for the mixture to loads of at least 10 psi at temperatures of 600.degree.-800.degree. F. while being thermally stable; a thermally stable thermoset polymer matrix adhering the mixture to the support or the wear surface, the polymer having inherent hydrocarbon chemical attraction to form a tenacious oil film of the lubricating oil on the wearing surface. A method of making anti-friction coated surfaces comprising providing a light metal based cylinder surface (i.e., metal base or alloys of aluminum, titanium, or magnesium); exposing nonoxidized metal of the surface; applying a high elastic modulus load-supporting metal layer onto at least portions of the light metal cylinder surface; and simultaneously distributing a solvent-based solid film lubricant mixture and thermoset polymer onto at least portions of the layer at about room temperature to form a coating of desired thickness. An engine block with one or more anti-friction coated cylinder bore surfaces, comprising a hard, load-supporting face on the bore surface; and a coating on the face comprised of an oil-attracting solid lubricant mixture and a thermoset polymer that supports loads of at least 10 psi at temperatures of 600.degree.-800.degree. F. and is stable at such temperatures.
