摘　　要：分析了在高速滑动干摩擦过程中热的产生和扩散机理、摩擦温度的测定与分析,讨论了摩擦热效应对配副材料摩擦磨损性能的影晌。结果表明:在摩擦过程中,摩擦热的形成是显著的;由粗糙表面产生的摩擦热作用在粗糙表面进而影响粗糙表面的形貌;摩擦热是影响摩擦副摩擦性能变化的主要因素;在研制摩擦材料时应充分考虑配副材料的耐热性与散热性等物性,进行优化选材。The creation and diffusion mechanism of heat, the measure and analysis of the temperature of wear surface under high speed dry sliding were analyzed. The influence of thermal results on tribological performance of friction pair was discussed. The results show that the friction heat is obvious under high speed dry sliding;the friction heat formed in the roughness surface influences surface morphology;the friction heat is the major factor to influence the friction behaviorof friction pair. The thermal stability and the property of rejection of heat of the friction pair must be considered when developing the friction materials.
