Aluminum alloy has been used in several kinds of industries because it has a lot of advantages. However, it has poor wear-resistance, so in order to solve this problem, Diamond Like Carbon (DLC) coating which indicates high tribological properties was performed. Furthermore, in this study, in order to increase adhesion strength and to prevent the substrate from decrease of fatigue strength, original laminated DLC coating was suggested by using Unbalanced Magnetron Sputtering (UBMS) method. Wear and fatigue tests were carried out. Aluminum alloy coated DLC indicated excellent tribological properties. Furthermore, it indicated high fatigue strength compared with substrate only.
