准高速电力机车粉末冶金制动闸瓦材料研究
RESEARCH ON POWDER METALLURGY BRAKE SHOES FOR ELECTRIC LOCOMOTIVE
【摘要】 本文主要从铁基和铁-铜基二个方面对准高速电力机车用粉末冶金制动闸瓦材料进行了研究。结果表明,铁基材料的耐磨性、摩擦系数稳定性均优于铁-铜基材料;并用粘着摩擦理论对实验结果进行了分析讨论。
【Abstract】 The iron-base and iron-copper base powder metallurgy brake shoes materials for quasi-high-speed electric locomotive were studied. The results showed, the wearability and friction-coefficient stablity of iron-copper-base material; the experimental results are identified by theadhesion-friction theory.
