摘要：

In this work, plasma electrolytic oxidation coating was formed on aluminium alloy in a cheap and inexpensive electrolyte to improve its wear resistance. It was found the micro-hardness of coatings increased first and then decreased with increasing the oxidised time. It was showed that the specimen treated under the time of 35 minutes exhibited the highest micro-hardness and lowest wear loss. The surface and cross-sectional morphology indicated that the coatings have a dense structure with low porosity. The presence of wear scars on the worn surface morphology demonstrates that the three-body rolling was the main wear mechanism for coated specimen. X-ray diffraction results showed the coating was formed mainly from alpha-Al2O3 and gamma-Al2O3.
