Abstract

Al₂O₃ ceramic coatings are widely used due to their excellent wear resistance, but comparative studies on the sliding wear mechanisms with typical metal pairing materials are rarely reported. In this study, the frictional behavior of Al₂O₃ coatings against 316L stainless steel, H62 brass, and TC4 titanium alloy were systematically studied using a CSM friction tester. To study of the wear mechanism of different friction parts, a thoroughly comparative analysis was performed via scanning electron microscopy, high-resolution X-ray diffraction and multifunctional X-ray photoelectron spectroscope. The findings reveal significant differences in tribological performance across these friction pair systems. The crystal structure of the friction pair is the basis for determining the intrinsic tribological behavior of the material, the mechanical properties predominantly govern the distribution of contact stresses, while frictional heat induces interfacial chemical reactions that lead to the formation of a friction induced third body, collectively influencing the friction and wear behaviors of the pairs.

Al2O3陶瓷涂层与316L、H62和TC4基体的摩擦学行为及优势机理

Al2O3陶瓷涂层因其优异的耐磨性而得到广泛应用，但与典型金属配对材料滑动磨损机理的对比研究很少报道。本研究采用CSM摩擦试验机系统研究了Al2O3涂层对316L不锈钢、H62黄铜和TC4钛合金的摩擦行为。为了研究不同摩擦件的磨损机理，采用扫描电镜、高分辨率x射线衍射和多功能x射线光电子能谱进行了全面的对比分析。研究结果揭示了这些摩擦副系统在摩擦学性能上的显著差异。摩擦副的晶体结构是决定材料内在摩擦学行为的基础，机械性能主要控制接触应力的分布，而摩擦热诱导界面化学反应导致摩擦诱导第三体的形成，共同影响摩擦副的摩擦磨损行为。

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
