TA15钛合金是一种广泛应用于航空航天的金属材料，制备TA15超疏水表面能够有效的抑制飞机在高空中产生结冰结霜现象，但具有超疏水性能的表面微结构在磨损中极易失效。为了提高TA15钛合金超疏水表面的耐磨性能。通过干膜掩模的方法在金属基体上附着一层预定图案的绝缘网，使未被绝缘层覆盖的金属表面发生电化学反应，进而形成一种拓扑框架结构包裹着的超疏水表面。当采用0.2mol/L的NaBr溶液作为电解液时，使用正四边形掩模版对TA15钛合金进行电解加工，电加工参数为0.8A/cm2，12min时其表面呈超疏水性。并且在被磨损超过1200cm后仍能保持接触角150.1°滚动角21.3°的疏水性。对电解加工后的TA15钛合金表面进行EDS图谱及SEM电镜图像分析，可以得出通过掩模电解方法可以有效的提高超疏水表面的耐磨性，同时掩模电解产生的框架结构不会破坏原表面的疏水性。经过测试这种超疏水表面具有良好的自清洁性与抗粘附性。

TA15 titanium alloy is a metal material widely applied in aerospace and aviation. Superhydrophobic surfaces prepared with TA15 titanium alloy can effectively suppress icing and frosting in aircraft at high altitudes, however, the microstructure of superhydrophobic surfaces is prone to lose of efficacy in wear. To improve wear resistance of superhydrophobic TA15 surfaces, an insulation mesh with predetermined pattern was attached to the base metal by a dry-firm photoresist to set off an electrochemical reaction on the metal surface without an insulation coating, forming a superhydrophobic surface in topology. In electrolyte of 0.2 mol/L NaBr solution, TA15 was electrochemically machined using a square mask with an electrical machining parameter of 0.8 A/cm2 for 12 minutes as its surface was superhydrophobic. The worn surface upwards of 1,200 cm maintained superhydrophobic at contact angle of 150.1o and rolling angle of 21.3o. The EDS maps and SEM images of electrochemically machined TA15 titanium alloy surface showed that the use of a dry-film photoresist mask could effectively improve the wear resistance of the superhydrophobic surface, while the structure generated from mask electrolysis did not damage the hydrophobicity of the original surface. The test showed that the superhydrophobic surface had good self-cleaning and anti-adhesion properties.
