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，对于构成汽车等许多机器部件的动力传递机构，从全球环境保护的观点出发，在世界范围内提出了机器的节能。特别是，构成机器的动力传动机构的齿轮的机械特性、强度的要求每年也很严格。然后，表面改性处理作为满足这种高要求的技术给出。在这项研究中，我们评估了混合表面改性的影响，这是结合DLC（类金刚石碳）涂层，产生低摩擦和良好的磨损性能对滚动接触疲劳性能和SRIQ（超快速感应加热和淬火），通过齿轮试验产生高强度。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.
