光亮的镍層不仅可以得到美丽的外观,而且还能防止我们使用的金屬制品的锈蝕。通常鍍镍是用电解法(常叫电镀法)来进行的。但是这方法有重大的缺点。其中之一就是:附在金屬表面上的镍層是厚薄不匀的。由于电流在电镀槽中分布的特点,大部分电流通过制品的凸出部份,因此沉积在凸出部份的镍層总是比凹部或 The bright nickel layer not only gives a beautiful appearance, but also prevents the corrosion of the metal products we use. Nickel plating is usually performed by electrolysis (often called electroplating). But this method has major shortcomings. One of them is that the nickel layer attached to the metal surface is uneven. Due to the distribution of current in the plating bath, most of the current passes through the protruding part of the product, so the nickel layer deposited on the protruding part is always more than the recessed part or
