摘要：
A method for making a composite aluminum article comprises the steps of electrochemically or chemically adsorbing fine particles of a polytetrafluoroethylene to the surface of a hard anodic oxide film of an aluminum material or an aluminum alloy material, and drying the aluminum material or the aluminum alloy material. Thereafter, the aluminum material or the aluminum alloy material and an opposite member which slides along the aluminum material or the aluminum alloy material are rubbed together, and a lubricating film is thereby formed.
