| Abstract: | The formula of micro-arc oxidation electrolyte was optimized and the properties of micro-arc oxidation film were analyzed through single factor experiment.The optimum formula and process parameters were determined as follows:Na2SiO3 20 g/L,Na2B4O7 30 g/L,NaOH 30 g/L,oxidation time 20 min.Experimental results showed that a dark-gray micro-arc oxidation film featuring smooth surface and compact structure was obtained when adding nickel acetate into the electrolyte.The micro-arc oxidation film was thick and has better corrosion resistance. |
