Abstract
A lubrication-treating process for an Al or Al alloy material is carried out by cleaning the material; applying an anodic oxidation to the cleaned material surface to form a 3 to 30 .mu.m thick anode oxidation coating; and forming a lubrication coating including a polyester resin (30 to 70 mass parts), a particulate PTFE (30 to 70 mass parts) and ceramic (alumina) particles (0.5 to 5 mass parts), and 2 to 20 .mu.m thick, to thereby impart excellent resistances to adhesion and seizure, and a low friction, to the Al or Al alloy material at a low cost and with no or a very low pollution of the environment.
