| Research Abstract |
Recently, the energy saving of machine is advanced from the viewpoint of the global environmental protection on the world scale as for the power transmission mechanism that composes a lot of machine parts such as cars. Especially, demands of the gearwheel of the power transmission mechanism that composes the machine concerning a mechanical characteristic, strength are also severe every year. Then, the surface reforming processing is given as a technology to fill such high demands. In this study, we evaluated the influence of hybrid surface modification which was combined DLC (Diamond Like Carbon)coating that creates low friction and excellent wear properties on rolling contact fatigue properties and SRIQ (Super Rapid Induction Heating & Quenching) that created high strength by gear test. The obtained conclusion is shown below.
