摘　　要：在常规铝合金硬质阳极氧化液中添加聚四氟乙烯颗粒,在6063铝合金表面形成含有聚四氟乙烯颗粒的复合硬质阳极氧化层。氧化层中聚四氟乙烯颗粒直径约为2μm,面积百分比含量为2%～3%。经过1h阳极氧化处理可得到70μm厚的复合阳极氧化层,其表面硬度为400～480HV0.1。在滑动干摩擦条件下与淬火钢对磨的平均摩擦因数为0.11,比常规硬质阳极氧化层的摩擦因数降低17%。A composite hard-anodized coating containing micro PTFE (polytetrafluoroethylene) particles on aluminium alloy 6063 was produced by adding micro PTFE particles into the traditional hard anodizing solution. The size of the PTFE particles is around 2 μm in diameter and the content of the PTFE particles in the composite coating is within 2%～3% by area percentage. Thickness of the composite coating can reach 70μm after one hour's anodizing. Its surface hardness is between 400～480 HV0.1. The average friction coefficient of the composite coating against steel under dry friction test is 0.11, which is 17% lower than that obtained by traditional hard anodizing.
