| 摘 要： | 采用自动化高速电弧喷涂技术在AZ91镁合金基体上制备了FeCrBSiMnNbW非晶纳米晶涂层.研究了涂层材料在干摩擦条件下的摩擦学性能.采用配备有能谱分析仪（EDAX）的扫描电子显微镜（SEM）和X射线衍射仪（XRD）对涂层的微观组织结构进行了表征.采用显微硬度计和纳米压痕仪对涂层的力学性能进行了分析,摩擦磨损试验在UMT-2型摩擦磨损试验机上进行,并采用三维白光干涉表面形貌仪（Phase Shift MicroWAM-3D）测定磨损量.结果表明：涂层组织均匀、结构致密、氧化物含量低,涂层主要由非晶相和纳米晶相组成;涂层具有较高的硬度和弹性模量;在相同的试验条件下,非晶纳米晶合金涂层的相对耐磨性是传统3Cr13涂层的3倍;磨损机制主要为典型的脆性剥落.
