In recent years, DLC(Diamond Like Carbon) coating, which is well known for its high hardness and excellent ware resistance, has been widely used in several kinds of industries. However, in general, it is not easy to control the friction coefficient of DLC coating. So, in order to apply DLC coating for more machines and equipments, it is important to clarify the method of controlling friction coefficient of DLC coating more easily. So, in this study, DLC coating was performed on the surface of substrate which was formed micro-dimples by using Fine Particle Bombardment(FPB). Three types of coated specimens with different surface roughness were prepared and wear tests were carried out. The coated specimens which was formed micro-dimples indicated stable friction coefficient for long distance significantly. Furthermore, it is possible to control the friction coefficient of DLC coating easily by changing the surface roughness of substrate; the rougher the surface roughness, the higher the friction coefficient.
