摘要： This invention relates to a surface treatment method comprising the steps of soaking aluminum or an aluminum alloy in a treating solution containing a fluorine compound and ammonium silicofluoride, and treating the aluminum or aluminum alloy in the treating solution at a temperature in the range of 70 to 100° C.; a piston having undergone such a surface treatment; and a piston coated with a film consisting of an Al—OH—F compound, as well as a sliding member in which its sliding surface and the like are coated with a slide film consisting, for example, of a compound of aluminum, fluorine and the hydroxyl group; and a surface-treating film for an aluminum alloy which is formed on a surface of aluminum or an aluminum alloy and consists of an aluminum fluoride hydroxide compound and silicon particles dispersed therein. The present invention can provide a surface treatment method which requires simple equipment, can reduce treating costs, and can yield aluminum or an aluminum alloy having excellent abrasion resistance, corrosion resistance and other properties, as well as sliding members and pistons having excellent abrasion resistance and other properties.
