摘要
采用不同的烧结温度,通过粉末冶金的方法制备了铜基粉末冶金摩擦材料,在MM-1000型摩擦试验机上进行了模拟制动实验。结果表明,烧结温度由900℃至930℃,材料的制动、磨损性能得到显著改善,继续升温至1000℃,材料性能变化不大。借助扫描电镜、光学金相显微镜对不同烧结温度条件下材料的显微组织、摩擦表面及磨屑形貌进行了观察分析,阐述了烧结温度对铜基粉末冶金刹车材料摩擦磨损行为的影响。
The materials were produced by P/M route and wear test was carried out in a MM-1000 type machine. The results showed that as the sintering temperature increased from 900℃ to 930℃. the abrasion properties increased notably;when the sintering temperature increased from 930℃ to 1000℃, the abrasion properties changed inconspicuously.The resultant mechanisms have been discussed by observation and analysis of the microstructures and properties of Cu-based friction materials with different sintering temperature.
