Wear properties of anode oxidation coating in the surface of ZL101 aluminium alloy

摘要

The oxidation film was prepared by anode oxidation method on ZL101 aluminium surface, its morphologies, compositions and phases were characterized with SEM (Scanning Electron Microscope), optical profiler, EDS (Energy Disperse Spectroscopy), respectively, its friction coefficient and abrasion performance were analyzed by wear test, and its wear mechanism was discussed. The results show that the thickness of anode oxidation layer is about 35-40μm, under dry friction condition, sliding friction coefficient is 0.65-0.72, the wear forms are abrasive attrition and adhesion wear, the low friction pair between furrows effect and adhesion effect improves the wear performance of anode oxidation film on ZL101 aluminum alloy surface.
