摘　　要：介绍了一种TC4钛合金表面电镀镍工艺,该工艺流程简单,化学除油、酸洗、活化后直接电镀镍。采用本工艺可在TC4钛合金表面制得均匀、平整和结合力合格的镍镀层,提高了钛合金基体的显微硬度和耐磨性。A process for nickel plating on TC4 titanium alloy was introduced. The process flow is simple as shown by directly nickel plating after chemical degreasing, pickling and activation successively. A uniform and smooth nickel coating with qualified adhesion strength can be obtained on the surface of TC4 titanium alloy by using the given process, resulting in the improvement of microhardness and wear resistance of titanium alloy substrate.
