一、概述电镀过程是在金属和电解液相接触的界面上发生的电化学过程。为使钢丝获得良好的电镀层,镀前钢丝的表面处理工作至关紧要。在我国制品行业中,一般采用电解酸洗法清除钢丝表面的氧化皮、铁锈、油污等。所谓电解酸洗,是指钢丝接通直流电源的正极或负极,借助外加电势,加剧酸洗液中的电化反应,从而可使反应生成的气体(氢气 I. Overview The electroplating process is an electrochemical process that takes place at the interface where metal and electrolyte come into contact. In order to get a good electroplating layer of steel wire, the surface treatment of the steel wire before plating is very important. In China’s product industry, the general use of electrolytic pickling to remove the surface of the wire oxide, rust, oil and so on. The so-called electrolytic pickling, refers to the wire connected to the DC power supply of the positive or negative, with the help of potential, exacerbated acid pickling in the electrochemical reaction, which can react the gas generated (hydrogen
