摘要：
本发明提供了一种用于镁合金微弧氧化制备古铜色陶瓷膜层的电解液，以及利用该电解液处理镁合金表面获得古铜色陶瓷膜层的方法，所述电解液为偏铝酸钠、氢氧化钠、酒石酸和钨酸钠的水溶液，电解液组成如下：偏铝酸钠10-20g/L，氢氧化钠1-10g/L，酒石酸1-10g/L，钨酸钠1-10g/L，溶剂为去离子水。依发明所述电解液对镁合金表面进行微弧氧化，所得到的陶瓷膜层表面较光滑，颜色均匀，且膜层表面均匀平整。
摘要（英）：

The present invention provides an electrolyte for preparing a bronze-coloured ceramic film layer by micro-arc oxidation of magnesium alloy and a method for using the electrolyte for surface treatment of the magnesium alloy to obtain the bronze-coloured ceramic film layer, the electrolyte is an aqueous solution of sodium meta-aluminate, sodium hydroxide, tartaric acid and sodium tungstate, the electrolyte comprises 10-20g / L of sodium meta-aluminate, 1-10g / L of sodium hydroxide, 1-10g / L of tartaric acid and 1-10g / L of sodium tungstate, and deionized water is used as a solvent. According to the method, the electrolyte is used for micro arc oxidation on the surface of the magnesium alloy, the surface of the obtained ceramic film layer is smooth, the color is uniform, and the surface of the film layer is even and even.
