Friction and Wear Behavior of Al2O3-13%TiO2 / Iron-Based Amorphous AlloyComposite Coating at Room Temperature
摘 要
利用等离子喷涂技术制备含质量分数15% Al2O3-13%TiO2陶瓷相的Fe45Cr16Mo16C18B5铁基非晶合金复合涂层并进行销盘式摩擦磨损试验,通过与铁基非晶合金涂层进行对比,研究了复合涂层在不同载荷(20,30,50 N)和销轴转速(300,500,800 r·min-1)下的摩擦磨损行为,分析了其磨损机制。结果表明:当销轴转速为300 r·min-1时,不同载荷下复合涂层的磨损率较铁基非晶合金涂层降低近50%,复合涂层的磨损机制随着载荷的增大由磨粒磨损转变为疲劳磨损;当载荷为30 N时,复合涂层的磨痕深度与磨损率随销轴转速的增加先增大后减小,均在转速为500 r·min-1达到最大,在销轴转速为500 r·min-1和800 r·min-1时复合涂层均表现为黏着磨损。
Abstract
Composite coating of Fe45Cr16Mo16C18B5 iron-based amorphous alloy containing 15wt% Al2O3-13% TiO2 ceramic phase was prepared by plasma spraying technology, and was subjected to a pin-disk friction and wear test. By comparing with those of iron-based amorphous alloy coating, the friction and wear behavior of the composite coating under different loads (20, 30, 50 N) and pin rotational speeds (300, 500, 800 r·min-1) was studied, and its wear mechanism was analyzed. The results show that when the pin rotational speed was 300 r·min-1, the wear rate of the composite coating decreased by nearly 50% compared with that of the iron-based amorphous alloy coating under different loads, and the wear mechanism of the composite coating changed from abrasive wear to fatigue wear as the load increased. When the load was 30 N, the wear scar depth and wear rate of the composite coating first increasd and then decreasd with the increase of the pin rotational speed, both reached the maximum at 500 r·min-1. When the pin rotational speed was 500 r·min-1 and 800 r·min-1, the wear mechanism of the composite coating was adhesive wear.
