    Microstructure and Wear Resistance of Ti(CN)/TiC/Al2O3 Multilayer Coating Prepared by Chemical Vapor Deposition

      摘要
    • 摘要: 采用化学气相沉积技术在42CrMo钢基体表面制备了Ti(CN)/TiC/Al2O3多层涂层, 分析了多层涂层的断面形貌、元素分布和物相组成, 并研究了多层涂层的显微硬度及其与基体的界面结合力、耐磨性能。结果表明: Ti(CN)/TiC/Al2O3多层涂层的结构较致密, 主要由TiC0.2N0.8、TiC、α-Al2O3 和Ti2O3组成, 厚度约10 μm, 其显微硬度约2 654 HV, 涂层与基体间的界面结合力可达62 N;与基体相比, 多层涂层的平均摩擦因数约降低了23%, 磨损量约减少了50%, 其磨损机制为疲劳磨损和磨粒磨损。

       

      Abstract: Ti(CN)/TiC/Al2O3 multilayer coating was prepared on 42CrMo steel substrate by chemical vapor depostion(CVD) technology, and the cross-section morphology, element distribution and phase composition of the coating were analyzed, and its microhardness, adhesion and wear resistance were studied. The results show that the multilayer coating had dense structure and was composed of TiC0.2N0.8, TiC, α-Al2O3 and Ti2O3, and its thickness was about 10 μm. The microhardness of the coating was approximately 2 654 HV, and the adhesion between the coating and the substrate was about 62 N. Comparing with the substrate, the average friction coefficient of the coating was decreased by 23% and the wear mass loss was reduced by 50%. The wear mechanism of the coating was fatigue wear and abrasive wear.
