钝化膜的形成与溶液的成分、PH值、温度及处理时间有关，其中PH值是最重要的因素。一方面基体金属需要在一定的PH值条件下溶解，另一方面膜的生成速率也与PH值有关。本实验主要用开路点位-时间曲线法、Tafel曲线法和盐雾腐蚀实验来研究钝化液PH值与钝化膜耐腐蚀性的关系及确定最佳PH值。
化学复合镀镍 钝化膜 耐腐蚀性

Answer 1

The formation and passivation solution composition, PH value, temperature and time, PH value is the most important factor. Hand in metal substrate to dissolve PH condition, on the other hand, the membrane formation rate and PH value. This experiment mainly with open point - time curve method, Tafel curve method and salt spray test to study corrosion passivation solution PH value and passivation membrane resistance and determine the optimal PH value.
