| titleOfInvention | Method for preparing oxide film on surface of magnesium alloy by utilizing micro-arc oxidation |
| abstract | A method for preparing oxide film on magnesium alloy surface by micro-arc oxidation comprises placing magnesium alloy in alkaline electrolysis apparatusIn the electrolytic bath of the liquid, magnesium alloy is used as an electrolytic anode, the electrolytic bath is used as an electrolytic cathode, voltage is applied to cause plasma discharge on the magnesium alloy, micro-arc oxidation is utilized to form an oxide film on the surface of the magnesium alloy, and the alkaline electrolyte comprises 8-12 g/L, Na NaOH 2 SiO 3 10—15g/L、KF 6—8g/L、H 2 O 2 2-3 mL/L, 6-8 mL/L of glycerol, 1-2 g/L of ethylene diamine tetramethylene phosphonic acid sodium and the balance of water; in the process of micro-arc oxidation, zeolite powder and gamma-alumina nano micro powder are sequentially added into the electrolyte, and then the micro-arc oxidation reaction is continued until the preparation of the oxide film is finished. The reaction process of micro-arc oxidation is influenced by the comprehensive action of a plurality of components, the number of micropores on the surface layer of the oxidation film is reduced, the compactness of the oxidation film is fundamentally improved, and the corrosion resistance is enhanced. |
