摘要
利用ＲＦＴ－Ⅲ往复摩擦磨损试验机测试了Ｃｕ粉（２００目）及纳米Ｃｕ粉填充聚甲醛所形成复合材料的摩擦磨损性能，并利用电镜、ＸＰＳ和ＡＥＳ研究了其磨损机理。研究发现，填加一定量Ｃｕ粉（２００目）及纳米Ｃｕ粉均可降低聚甲醛的磨损，但填加纳米Ｃｕ粉效果更好。ＸＰＳ分析钢对偶面发现，Ｃｕ粉（２００目）在摩擦过程中生成Ｃｕ２Ｏ，而纳米Ｃｕ粉在摩擦过程中生成Ｃｕ（－ＣＨ２－Ｏ－）ｎ。
Cu (nanometer)/POM, Cu (125 μm)/POM composites were tested by RFT Ⅲ reciprocating friction tester and their friction and wear behaviors were studied. The wear of POM is reduced by filling Cu (nanometer) or Cu (125 μm), but the effect of filling Cu (nanometer) is better. It is found by using XPS that Cu (125 μm) is turned into Cu 2O and Cu (nanometer) is turned into Cu(-CH 2-O-) n on the steel counterface.
