【Abstract】 This paper presents a kind of plasma MAO(micro arc oxidation)pulsed power supply with the function of constant current constant voltage. The importance of constant current constant voltage in MAO craft is analyzed. The practical implemented measure and experiment results are given. Through the analyse of the result, the difference of this control method and traditional method are compared. On the basis of this control method, the merits of coating speed, thickness, and qualities are showed as well.更多还原
