In this test the influences of the beginning and finishing voltage on ceramic layer in magnesium alloy micro-arc oxidization are studied. It shows that the voltage would decide the thickness and surface roughness of the ceramic layer. When the beginning voltages are equal, the thickness of ceramic layer would increase with the finishing voltage; when the finishing voltages are equal, the thickness of ceramic layer would increase with the beginning voltage. The surface roughness would increase with finishing voltage. It doesn't show a clear relation between the roughness and the beginning voltage.
