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 μm 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 μm 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.
Claims6
A process for lubrication-treating an aluminum or aluminum alloy material, comprising:
- cleaning a surface of the aluminum or aluminum alloy material;
- applying an anodic oxidation treatment to the cleaned surface of the aluminum or aluminum alloy material, to form an anodic oxidation coating layer having a thickness of 3 to 30 μm on the wear-resistant material surface;
- and
- forming a lubrication coating layer comprising a polyester resin, a particulate polytetrafluoroethylene and ceramic particles and having a thickness of 2 to 20 μm on the anodic oxidation coating layer.
