The Improvements of rolling contact fatigue Properties of Steel modified Hybrid Surface Modification combined DLC coating and Super Rapid Induction Heating & Quenching

近年来，从全球环境保护的角度出发，在世界范围内提出了机器的节能问题，如汽车等组成大量机器部件的动力传动机构。特别是组成机器的动力传动机构的齿轮关于机械特性、强度的要求也每年都很苛刻。然后，提出了一种满足这种高要求的表面重整工艺。在这项研究中，我们通过齿轮测试评估了混合表面改性（DLC （Diamond Like Carbon）涂层）对滚动接触疲劳性能的影响，DLC （Diamond Like Carbon）涂层产生了低摩擦和优异的磨损性能，SRIQ（超快速感应加热和淬火）产生了高强度。所得结论如下所示。

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.
