制动系统是高速列车安全运行的关键核心部件,铜基粉末冶金摩擦材料具有组织均匀、高耐磨、高硬度和摩擦因数稳定的特点,能充分发挥基体材料、摩擦组元及润滑组元各自的优点以及它们之间的协同作用,成为高速列车制动闸片的首选材料.随着列车行驶速度的不断提高,摩擦制动产生的温度越来越高对摩擦材料的高温稳定性和抗氧化性提出了更高的要求.因此,主要论述了铜基粉末冶金摩擦材料中摩擦组元的种类及添加方式对材料组织结构和摩擦性能的影响,对摩擦组元与基体的结合效果和摩擦磨损机制等方面进行了总结和评述,对铜基粉末冶金摩擦材料的未来发展趋势进行了展望.
Research progress on the influence of friction components on the properties of copper-based friction materials
The braking system is the key and core component of the safe operation of high-speed train.Copper-based powder metallurgy friction material has become the preferred material for high-speed train brake plate be-cause of its characteristics of uniform structure,high wear resistance,high hardness and stable friction coefficient,and can give full play to the advantages of matrix material,friction component and lubrication component and their synergies.With the continuous increasement of train speed,the temperature of friction braking has become higher and higher,which puts forward higher requirements on the high temperature stability and oxidation resistance of friction materials.This paper primarily discusses the effects of the types of friction components and adding meth-ods on the structure and friction properties of copper-based powder metallurgy friction materials,and the bonding effect between friction components and matrix and the friction and wear mechanism are summarized and reviewed.The future development trend of copper-based powder metallurgy friction materials is prospected.
