摘要
采用销盘型磨损试验研究了Ｆｅ－３Ｃｒ－２Ｎｉ－２Ｃｕ－０．８Ｃ－３ＷＣ烧结钢密度对其磨损率的影响；通过扫描电子显微镜（ＳＥＭ）的磨损表面形貌观察，分析讨论了孔隙在室温，５００℃条件下磨损过程中的作用。结果表明，密度对室温磨损影响较大，密度提高则磨损减小；密度对高温磨损率影响不大，磨损以混合机制发生。
Influence of the density of Fe-3Cr-2Ni-2Cu-0. 8C-3WC sintered steel on its wear rate has been studied by using pin-disk type wearing test. The morphology of wearing sruface hat been surveyed by SEM. The role of pores on wearing process under the conditions of room temperature and 500℃ has been analyzed.
