【Abstract】 Technical regime and process of conductive chemical oxidizing on aluminum and its alloys were introduced. With orthogonal test, effects of oxidizing time, content of chromic anhydride, solution temperature and baking temperature on oxidizing film were studied. In result, optimum process parameters were obtained. Experimental results show that the conductive chemical oxidizing film has vivid and even appearance and greatly-improved protection character.更多还原
