In recent years, against the background of weight saving and downsizing in machines and devices, it is important subject to downscale mechanical parts which was contained in them. So in this study, in order to achieve power transmission parts like compact gearwheel which indicates high performance properties, hybrid surface modification which was combined SRIQ(Super Rapid Induction heating & Quenching) which creates high fatigue strength and DLC(Diamond Like Carbon) coating which are well known for their high hardness, low friction and excellent wear resistance was performed. And, in order to prevent the base material from decrease of fatigue strength, DLC was coated by using UBMS (Unbalanced Magnetron Sputtering) method which can coat at low temperature. Rolling-Sliding tests was carried out. It was clear that it is possible to create excellent fatigue strength by performed hybrid surface modification. The above -mentioned is shown below.
