Progress in Studies on Tribology of Metal-based Composite Coatings

对金属基复合材料涂层的减摩抗磨性能和制动摩擦性能、涂层的摩擦磨损机理和影响涂层摩擦磨损性能若干因素的研究现状进行了综述,并指出有关涂层材料与基体的匹配规律、不同基材上涂层制备工艺的优化、多组元涂层及多层涂层的设计和制备工艺、纳米尺度涂层技术、涂层内应力的控制、涂层减摩抗摩机理以及制动摩擦机理等方面是今后在金属基复合材料涂层摩擦学方面值得进一步研究的问题。

The progress in studies on the tribological properties and the braking friction behaviors, as well as the friction and wear mechanisms of metal-based composite coatings is reviewed. Some factors influencing the friction and wear behaviors of the coatings are described. Moreover some problems needed to be investigated further in the field of tribology of metal-based composite coatings, such as the matching law of substrates and coatings, the optimization of coating preparation techniques, the design and preparation technique of multilayer and multicomponent coatings, the nano coating technology, the control of coating’s internal stress, the coating’s braking friction mechanism and friction-reduction and wear-resistance mechanisms, are pointed out.
