With performance enhancement and high quality of transportation equipment, friction evaluations of the slide machine structure become technological problem. In this study, the effect of surface modification with super hard and self-lubrication characteristics using PVD on slide was examined. It is result of testing as follow. (1) The each surface modification material was shown low friction. But there weredifference at the slide distance and wear amount for the surface modification. (2) The surface roughness of MoS_2/IN is rough. DLC films are almost smoothed. And contact area of DLC films is dependent surface roughness, hardness. (3) The adhesion of DLC (IP) is better than DLC (UBMS) by indentation shape of the Vickers hardness meter. (4) The difference of the strain amount of the interface arises, when the load is applied to the DLC film material, and it is the factor in which the peeling generated by this.
