The purpose of this study is to improve the wear resistant properties of DLC film coated on Cr-Mo steel used in seawater. DLC films are often used in sliding systems of machinery, but they are easily fractured and detached because of corrosion of the foundation material when these are used in corrosive environments such as in seawater. In this paper, a cathode rust prevention technique is attempted to prevent corrosion of the steel foundation using Zn material which is coated on the edge of the steel foundation. The wear tests show that DLC films coated on the Zn processed steel foundation possess good anti-wear performance in artificial seawater. Based on these tests and surface observations using several microscopes, the experimental results are discussed.
