【Abstract】 The micro-arc oxidation processes for several types of large-area wheel hubs made of magnesium alloy were investigated based on observation of phenomena in the micro-arc oxidation and testing of the craft. Thus the effects of electric current and potential on the micro-arc oxidation of Mg alloy were detailed, while the optimized parameters for the micro-arc oxidation of Mg alloy pieces with large area were established. It was anticipated that the relevant experimental results could be used to guide the design of the craft and power source for the microarc oxidation of large-area Mg alloy pieces.更多还原
