Al 7075 alloys are widely used in many mechanical parts because of their low density, light weight, and corrosion resistance. However, when mechanical parts are used in extreme environments such as high speed, high temperature, and high pressure, wear occurs more than allowable. To solve this problem, research and development of surface thin film deposition technology are increasing. Therefore, in this study, the wear characteristics were studied by depositing Ti films with excellent mechanical properties on Al 7075 according to the surface roughness by the deposition time. Results showed that 60’ sputtered specimens after polishing with alumina had the best wear resistance. In addition, the surface roughness of the base material and the deposition time of the thin film affected the wear resistance.
