镁合金表面化学处理溶液及表面化学处理方法
摘要：
本发明提供一种镁合金表面化学处理溶液及表面化学处理方法。根据本发明的镁合金表面化学处理溶液用于在镁合金表面生成光亮的转化膜，每升所述表面化学处理溶液包括乳酸10-200毫升、硝酸钠0.5-10克、磷酸20-500毫升和氯化亚锡0.1-10毫克，余量为水。根据本发明制得的镁合金表面转化膜附着力好，具有良好的耐磨性和耐腐蚀性，并且表面光泽度好可以直接用于各种装饰品上。另外，本发明的镁合金表面化学处理方法成本低、工艺简单、易于控制、适于大批量的工业化生产。
摘要（英）：

The invention provides a magnesium alloy surface chemical treatment solution and a surface chemical treatment method. The magnesium alloy surface chemical treatment solution of the invention is used to generate a bright conversion film on the magnesium alloy surface, and each liter of the surface chemical treatment solution comprises 10-200 ml of lactic acid, 0.5-10 g of sodium nitrate, 20-500 mlof phosphoric acid, 0.1-10 mg of stannous chloride, and the balance of water. The magnesium alloy surface conversion film prepared by the invention has good adhesion, good wear resistance and corrosion resistance, and good surface gloss, and can be used directly in various ornaments. In addition, the magnesium alloy surface chemical treatment method is low in cost, simple in process, easy to control, and is applicable to mass industrial production.
