Fretting Wear of DLC Film Coated on SUS304 Stainless Steel - The Wear Property in Seawater and Its Improvement

Abstract

 In this paper, the effects of DLC film coated on a stainless steel (SUS304) on fretting wear in seawater are examined. Special attention is focused on the effects of mating materials and the cathode rust prevention of Zn attached to the SUS304 on fretting damages. The experiments show that using soft copper alloy as the mating material is effective for preventing fretting damage of DLC film and that Zn is very effective for preventing damage in seawater.
