摘要
采用多弧离子镀工艺在40Cr表面制备了TiAlN/TiN复合镀膜,利用UMT-2摩擦磨损实验机考察了TiAlN/TiN膜层的承载能力和摩擦学性能,通过扫描电子显微镜观察了磨损试件的表面形貌,应用X射线能谱仪分析了磨痕中心区元素及其含量,通过40Cr基体和TiAlN/TiN膜在摩擦系数和磨损量方面的比较来评价TiAlN/TiN复合膜层的摩擦学性能。结果表明:TiAlN/TiN涂层与基体间的结合力是影响涂层承载能力的主要因素之一,TiAlN/TiN复合镀层的摩擦学性能优于40Cr基体,TiAlN/TiN复合镀层的减摩、耐磨性能优越,并能成功地抵抗磨粒磨损和粘着磨损。
TiA1N/TiN duplex coating is made on the surface of 40Cr steel by means of multi-arc ion plating technology. Carrying capacity and tribological properties of TiA1N/TiN duplex coating are investigated with a UMT-2 wear tester without lubrication. The surface morphology of wear specimens are observed by scanning electron microscope（SEM）. Elements of wear scar center and their content are analyzed by EDS. Tribological properties of TiA1N/TiN coating are evaluated through comparing with 40Cr in friction coefficient and wear volume. The results show that tribological properties of TiA1N/TiN duplex coating is better than 40Cr. The TiAlN/TiN films is superior in reducing friction and wear resistance, and can successfully resist abrasive wear and adhesive wear.
