为提高再制造曲轴的涂层性能和使用寿命,设计了FeAlCrNi/3Cr13、Ni95Al/3Cr13和1Cr13/3Cr13的3种复合涂层和不喷涂过渡层的3Cr13涂层,利用扫描电镜、能谱仪和微动摩擦磨损设备等测试技术分析了4种涂层的微观组织和微区成分组成,研究了喷涂不同过渡层对复合涂层结合强度的影响,重点考察了FeAlCrNi/3Cr13复合涂层的耐磨性能.结果表明,FeAlCrNi/3Cr13复合涂层组织致密,孔隙率约3.2％,氧化物含量低,涂层平均结合强度达到46.6 MPa,复合涂层在高载荷油润滑摩擦条件下的耐磨性能远高于基体45钢.FeAlCrNi/3Cr13复合涂层可以应用到高速电弧喷涂再制造修复曲轴产业中.
