随着载荷的增加，接触面正压力加大，接触面的摩擦系数逐渐减小。

两对摩件在滚动时，其之间的接触表面可视为两个区域，滑动区和无滑动区。无滑动区存在着制动剪切力，其大小受滑动趋势以及材料的机械性能等多种因素影响，粘结点在此区域形成；滑动区的剪切粘结点受到剪切阻力，而主动力克服该剪切阻力，带动从动件转动，传递力矩。两对摩件上任一点先进入无滑动区，如此循环。接触点发生粘合后被剪切受很多因素的影响，对受载荷的影响分析如下：

Residual stresses play a very important role in the properties of the coatings. When

残余应力对涂层性能产生至关重要的影响的，是涂层系统存在的残余应力。当残余应力值超出涂层和基体间的结合力时，残余拉应力将导致涂层发生破裂，而残余压应力则导致涂层翘曲变形，最终都将引起涂层的破损失效。此处说指的涂层系统是包括涂层和涂层与基体界面在内的所有部分。涂层系统的残余应力涉及的方面有：

残余应力的产生（来源）；残余应力的定性（定量）表达；残余应力的影响（决定）因素（直接决定因素/间接决定因素）以及减小残余应力的方法等。
对于残余应力的来源，目前的基本共识是：

2.1 残余应力产生的来源，分为三部分（...
