【Abstract】 The performance index of model 40 aluminum alloy cylinder after micro-arc oxidation was tested. The wear-resistant properties of micro-arc oxidation (MAO)coating on aluminum alloy were studied and compared with Cr-plating and wear-resisting P-V-Cu cast iron. The results show that the running stability and performance testing index of the cylinder with micro-arc oxidation are better than that of Cr-plating. The wear-resistance of micro-arc oxidation coating is also better than those of Cr-plating and the P-V-Cu cast iron under the condition of oil lubrication.更多还原
