Diamond-Like Carbon films (DLC films) show the excellent tribological properties. Therefore, many industrial applications are going on in variety of products. In these applications, DLC coatings on soft substrate materials are one of the problems. It is a fatal problem that deformation of substrate causes cracks and delaminations of DLC films from substrate. In this study, "segment-structured DLC coating" has proposed to solve this issue. Deformation behavior and tribological properties of segment structured DLC films are discussed from the results of 4-point bending test and ball-on-disk test, respectively. Finite element analyses of substrate deformation are also evaluated as compared with experimental results.
