One of the surface modification methods is proposed in this report to improve the wear resistance of light metal such as aluminum. At first alumite layer is formed on the surface of aluminum alloy A6061 which was used as the substrate with anodic oxidation treatment method, and then thin film of CrN is coated with sputtering method, and DLC film is finally coated with ion plating method. The influence of the thickness of the alumite film on wear-resistance is experimentally investigated. The main results obtained are as follows: (1) The critical load of the coated aluminum alloy with the alumite layer is higher than that without the alumite layer. (2) The wear amount of the coated aluminum alloy increased with the increase of the thickness of the alumite layer. (3) This combined surface treatment method can be found new surface modification method, and this method provided excellent adhesive strength and good wear-resistance.
