采用等离子喷涂工艺制备了Fe-Cr涂层。通过研磨、研磨或抛光工艺适当地加工喷涂涂层以获得不同的表面粗糙度。滚动接触疲劳（RCF）的实验进行了使用球盘装置。计算了涂层的RCF寿命。观察了涂层的磨损形貌。结果表明，涂层表面粗糙度对涂层的RCF行为有明显的影响。光滑涂层显示出更长的RCF寿命，并且总是因分层而失效。粗糙的涂层总是由于磨损或剥落而失效。光滑涂层的失效是由正交剪切应力和径向应力驱动的，而粗糙涂层的失效是由粗糙接触驱动的。
Fe-Cr coating was prepared by plasma-spraying process. As-sprayed coatings were machined by grinding, lapping, or polishing processes as appropriate to get different surface roughnesses. Rolling contact fatigue (RCF) experiments were conducted using a ball-on-disk setup. RCF lifetime of the coating was calculated. The worn morphologies of the coating were observed. Results show that surface roughness obviously influences RCF behavior of the coating. The smooth coatings showed longer RCF lifetimes, and always failed by delamination. The rough coatings always failed by abrasion or spalling. The failure of smooth coatings was driven by the orthogonal shear stress and radial stress, whereas the failure of rough coatings was driven by the asperity contact.
