摘要：
A method for the surface treatment of anodic oxide film is disclosed which comprises the steps of electrolyzing the porous surface of anodic oxide film of aluminium or aluminium alloy in an aqueous solution of ammonium thiomolybdate, optionally immersing it in an aqueous solution of ammonium thiomolybdate or alkali metal thiomolybdate and in dilute mineral acid or organic acid alternately, and subjecting it to a heat treatment so as to impregnate the micropores of the anodic oxide film with molybdenum sulfide and to fix the molybdenum sulfide therein.
