In this study, the diagnosis of the wear on the DLC (diamond-like carbon) film was enabled by analyzing /OG ratio of DLC wear particles. DLC film is expected as low friction and high wear resistance material. And, it is reported that the crystallographic structure on the surface is changed by the tribo-chemical reaction when the friction occurs. Then, authors established the technique for catching the structural change of the wear particles on the friction surface. This technique enabled the method of machine maintenance as well as "Oil analysis". In this report, authors firstly characterized shape and color of DLC wear particles by scanning electron microscopy and optical microscope. Secondly, they evaluated average thickness of DLC wear particles by specific wear rate and area of wear particles on membrane filter. As a result, increasing average thickness of DLC wear particles caused structural change of DLC wear particle.
