通过冷喷涂技术在350、450和550℃条件下将机械混合的Ti/Al粉末进行沉积获得3种Ti/Al涂层,通过扫描电子显微镜、X射线衍射表征Ti/Al涂层的微观组织形貌和物相结构,采用显微硬度计测量涂层硬度值,并对涂层的耐磨粒磨损性能进行研究.结果表明,3种涂层组织致密,其中以550℃喷涂温度条件下所制备涂层孔隙率最低(0.98%),且Ti颗粒不均匀地分布在变形的Al相中;冷喷后3种涂层物相与粉末相同,仍为Ti和Al两相;3种Ti/Al涂层的硬度值分别为(81.58±17.42) HV0.3,(82.4±28.15) HV0.3和(128.4±36.98) HV0.3.3种Ti/Al涂层的磨损机制为犁沟切削形式,其中以喷涂温度为550℃所制备的涂层磨损失量最小(13.93±1.21) mg.
