Surface T treatment method for magnesium alloy substrate

The invention relates to a surface T treatment method for a magnesium alloy substrate. The treatment method comprises the following steps of 1, cleaning the surface of the magnesium alloy substrate byusing a cleaning fluid; 2, treating the magnesium alloy substrate in alkali liquor; 3, preprocessing the magnesium alloy substrate in an acid solution containing dilute sulfuric acid; 4, soaking andcorroding the magnesium alloy substrate in a phosphoric acid solution; and 5, performing protection treatment on the magnesium alloy substrate in the polyalkenyl phosphate. The treatment method has the beneficial effects that the magnesium alloy generates a plurality of holes through a chemical means and is used for being connected with other materials. 本发明涉及镁合金基体表面T处理方法，包括如下步骤：步骤1、用清洗液对镁合金基体表面进行清洗处理；步骤2、镁合金基体在碱液中处理；步骤3、镁合金基体在含有稀硫酸的酸液中预处理；步骤4、镁合金基体在磷酸溶液中浸泡、腐蚀；步骤5、镁合金基体在聚烯基磷酸酯中进行保护处理。本发明的有益效果是通过化学手段使镁合金产生若干孔洞，用于与其他材料的接合。
