Keywords: electroless nickel-palladium gold, rhodium-ruthenium electroplating equipment, barrel plating equipment, anodizing equipment
In the field of anodic oxidation, it provides services for mainstream main engine factories in the industry, such as APPLE, DELL, HP, HUAWEI, ASUS, SONY, LENOVO, etc., grasps the operation process and process specifications of mainstream manufacturers, pays close attention to the new technology and development trend of anodic oxidation industry, and studies and updates anodic oxidation equipment to meet the needs of emerging processes.
电镀是一种电化学过程，也是一种氧化还原过程.电镀的基本过程是将零件浸在金属盐的溶液中作为阴极，金属板作为阳极，接直流电源后，在零件上沉积出所需的镀层.
不是所有的金属离子都能从水溶液中沉积出来，如果阴极上氢离子还原为氢的副反应占主要地位，则金属离子难以在阴极上析出.根据实验，金属离子自水溶液中电沉积的可能性，可从元素周期表中得到一定的规律，阳极分为可溶性阳极和不溶性阳极，大多数阳极为与镀层相对应的可溶性阳极，如：镀锌为锌阳极，镀银为银阳极，镀锡-铅合金使用锡-铅合金阳极.但是少数电镀由于阳极溶解困难，使用不溶性阳极，如酸性镀金使用的是多为铂或钛阳极.镀液主盐离子靠添加配制好的标准含金溶液来补充.镀铬阳极使用纯铅，铅-锡合金，铅-锑合金等不溶性阳极。
