摘要
通过分析块体非晶合金摩擦磨损过程的特点,总结了影响其摩擦磨损性能的主要因素,并从非晶合金与相应晶态合金对比、热处理和摩擦诱导晶化结构3个方面对其摩擦磨损性能研究现状进行阐述,指出:影响块体非晶合金摩擦磨损性能的主要因素为传热因素、配副材料和摩擦条件,且不同的影响因素之间相互关联、相互影响,即配副材料的热性能决定摩擦热导出速率,通过影响摩擦表面温度对摩擦过程产生影响,当摩擦条件改变时,非晶合金材料的稳定性发生变化,磨损量急剧增加或减小,从而影响其摩擦磨损性能.由于非晶合金的结构特点和摩擦磨损过程的特性,关于非晶合金与相应晶态材料摩擦磨损性能的对比研究,以及热处理和摩擦诱导晶化结构对块体非晶合金材料摩擦性能的影响研究中均存在矛盾性结论,需进一步研究非晶合金的结构与其摩擦磨损行为之间的关系,探究非晶合金磨损机制与转变规律,进而探索提升非晶合金耐磨性能的方法与途径.
By analyzing the characteristics of the friction and wear process of bulk amorphous alloys,the main influencing factors of its friction and wear performances were summarized.The research status of the friction and wear performances of bulk amorphous alloys were also described from three aspects: the comparison of the friction and wear performances of amorphous alloys and the corresponding crystalline alloys,the heat treatment and friction-induced crystallization structure.It was pointed out that the main factors affecting the friction and wear performances of bulk amorphous alloys were heat transfer factors,counter-face materials and friction conditions,and the different influencing factors were interrelated and affected each other.The thermal properties of the counter-face materials determined export rate of the friction heat,and affected the friction process by affecting the friction surface temperature.When the friction conditions change,the stability of amorphous alloy materials was changed and the amount of wear increased or decreased sharply,thereby affecting its friction properties.Due to the characteristics of the structure and the friction and wear process of amorphous alloys,there were contradictory conclusions in research of the comparative study on the friction properties of amorphous alloys and corresponding crystalline materials,the effect of heat treatment and friction-induced crystallization structure on the friction properties of bulk amorphous alloy materials.It is necessary to further study the relationship between the structure of amorphous alloys and its tribological behaviors,explore the wear mechanism and its transformation laws.Then the methods and approach of improving the wear resistance of amorphous alloys were obtained.
