DLC (Diamond-like carbon) film shows low friction coefficient against various materials and has high wear-resistance. This time, we focused on reduction of fretting wear and evaluated the antiwear behavior of DLC film. Continuous DLC film and segment-structured DLC film were fabricated on stainless steel thin plates (shims) by Plasma Based Ion Implantation and Deposition (PBII&D) method. Then, the shims were inserted between a ductile cast iron plate and an aluminum plate and bending fatigue tests were carried out up to a million cycles. The reduction mechanisms of the fretting wear in the DLC-coated shims case were investigated by evaluating the fatigue characteristics of the shims and a finite element analysis of these bending tests.
