摘要(Abstract)：

采用微弧氧化技术,在电解质溶液中添加蛇纹石微纳米颗粒,在ZL109铝合金表面原位生长陶瓷层。对未添加和添加蛇纹石微纳米颗粒制得的微弧氧化陶瓷膜层进行扫描电镜(SEM)、能谱(EDS)及X射线衍射(XRD)分析,并与铸铁试样进行摩擦磨损试验,探究蛇纹石微纳米颗粒对铝合金微弧氧化陶瓷膜层成分及摩擦学性能的影响。结果表明:在电解液中添加蛇纹石微纳米颗粒改变了微弧氧化陶瓷膜层的元素组成和相成分,在摩擦磨损试验中,微弧氧化膜层中的蛇纹石在摩擦能的作用下诱发了铸铁销表面的内氧化反应,在摩擦接触微区形成了Mg Si O3、Fe2O3及Fe3O4复合陶瓷表面自修复层,提高了铸铁销表面显微硬度,降低了摩擦磨损过程中的摩擦系数和铸铁销的磨损率。
