摘要
采用真空电弧离子镀工艺在H13钢表面制备Ti Al N/Cr Al N复合涂层,利用划痕试验仪、盘式摩擦磨损试验机、金相显微镜和努氏硬度计分析Ti Al N/Cr Al N膜层的结合力和摩擦学性能,金相组织形貌和试样表面的显微硬度。结果表明,Ti Al N/Cr Al N复合薄膜表面组织分布均匀,结合致密,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,Ti Al N复合涂层的摩擦性能优于H13基体和Cr Al N复合涂层的摩擦性能,Ti Al N/Cr Al N复合涂层的结合力分别为35 N和24 N,沉积有Ti Al N涂层试样表面摩擦系数最小,减摩效果最好,耐磨性能优越,并能有效地抵抗摩擦磨损。
Ti Al N/Cr Al N composite coating was prepared on H13 steel by vacuum arc ion plating process, and the adhesion and tribological properties of Ti Al N/Cr Al N coating were analyzed by scratch tester, friction and wear tester, metallographic microscope and hardness tester. The results show that the surface microstructure of Ti Al N/Cr Al N composite coating is uniform, and the bonding strength between the coating and substrate is one of the main factors that affect the carrying capacity of the coating. The friction properties of Ti Al N composite coating is better than that of H13 matrix and Cr Al N composite coating, and the binding force of Ti Al N/Cr Al N is 35 N and 24 N, respectively, The friction coefficient of Ti Al N coating is the smallest, the antifriction effect is the best, and the wear resistance is superior, and can effectively resist the friction and wear.
