The invention discloses a method for treating the surface of an aluminum-containing titanium alloy. The method comprises the following steps: cutting and forming a workpiece made of an aluminum-containing titanium alloy material; deburring and polishing the surface of the cut and formed material; preparing an electrolyte which comprises the following components: phosphate, aluminate, methanol and potassium hydroxide; immersing the formed workpiece into the electrolyte, connecting an anode with the workpiece and connecting a cathode with the inert conductor electrode by using a pulse power supply to form a loop; the inert conductor electrode is stainless steel; and pulse current is applied, the current density is 5-8 A/dm < 2 >, the pulse frequency is 50-200 Hz, the duty ratio is 10-30%, the electrolyte temperature is 35 +/-2 DEG C, the application time is 5-10 minutes, and a coating is formed on the surface of the workpiece. By means of the technical scheme, the problem that when the aluminum-containing titanium alloy is subjected to surface treatment, aluminate or aluminum oxide accumulation is formed, and consequently the porous structure is damaged is effectively solved, the uniformity degree of micropores in the surface of the film layer is improved, the biological activity of the film layer is guaranteed, and the application requirement of the medical field is better met.
本发明公开了一种含铝钛合金表面处理的方法，包括如下步骤：将含铝钛合金材料的工件切削成型；将切削成型的材料表面做去毛刺和打磨处理；配置电解液，组分包括磷酸盐、铝酸盐、甲醇、氢氧化钾；将成型后的工件浸入电解液中，使用脉冲电源，阳极与工件连接，阴极与惰性导体电极连接，构成回路；惰性导体电极为不锈钢；施加脉冲电流，电流密度为5~8A/dm2，脉冲频率50~200Hz，占空比10~30%，电解液温度为35±2度，施加时间为5~10分钟，在工件表面形成涂层。使用该技术方案，有效地解决了含铝钛合金进行表面处理时，形成铝酸盐或铝氧化物堆积而破坏多孔结构的问题，提高了膜层表面微孔的均匀程度，使得膜层生物活性得到保证，更好地适应医疗领域应用需要。
