| 摘 要： | 研究了5CrMnMo钢膏剂硼铝共渗层的高温磨损特性，结果表明，渗层磨损机制以疲劳剥落为主，兼有磨料磨损，剥落裂纹源于层中疏松、孔洞等缺陷处，并在周期机械应力周期热应力作用下扩展。

| Abstract: | In this paper,the high temperature wear characteristics of paste boron aluminized layer on 5CrMnMo steel were investigated.It has been shown that fatigue spalling is the main wear mechanism,abrasive wear also exist.The spalling cracks are initiated from microporosity,cavity,etc.existing in the cases,then are propagated by the cyclic mechanical stress and the cyclic thermal stress. |
