%X The porous anodic aluminum oxide (AAO) film on a pure aluminum substrate was prepared by a two-step anodization in a 0.3M oxalic acid solution and pore-enlargement treatment in the phosphoric acid aqueous solution at 50℃. The diameter of highly ordered pore on the AAO film was about 90nm, and the thickness of the AAO film was 3μm. The mineral oil was infiltrated in the ordered nanometer sized pores of AAO film on an aluminum substrate due to the capillarity effect. The friction coefficient was measured using a ball-on-disk tribotester.The tests were conducted at loads range from 490 to 2450mN and at sliding velocities beably improved the wear resistance. As compared to the porous AAO film, the oil-infiltrated specimen had low friction coefficient. With increasing the applied load and sliding velocity,the friction coefficient of the oil-infiltrated film decreased. It indicates that the oil-infiltrated AAO film produced a new way to modify the friction and wear of aluminum alloy.
