摘要：Alumina ceramics film which has high hardness, wear resistance and erosion resistance can be obtained using micro arc oxidation on the surface of aluminum alloy. The process parameters have great influence on the corrosion resistance of alumina ceramics film prepared by micro arc oxidation. In this research, the alumina ceramics film was gotten using micro arc oxidation with different process parameters. The corrosion resistance of ceramics coating prepared by micro arc oxidation on the surface of aluminum alloy was investigated by putting the samples into sodium chloride solution of the concentration 3.5%.T he influence regularity of process parameters such as current density, impulse frequency, duty ratio and process time on the corrosion resistance of alumina ceramics film was researched. This can provide basis for the optimization of process parameters.
