脉冲电镀是近十几年发展起来的新型电镀技术,在电镀行业中,引起了广泛的兴趣。目前,在国外已应用于贵金属的电镀生产中,并正在理论上作进一步的研究和探讨。在国内也有许多电镀工作者进行这方面的研究和试验。脉冲电镀能够得到通常直流电镀很难达到的高性能镀层,不仅能使镀层结晶细致,促使晶粒细化,减少镀层孔隙,而且,也可减少镀 Pulse plating is a new type of electroplating technology developed in recent ten years. It has aroused widespread interest in electroplating industry. At present, in foreign countries have been used in the production of precious metal plating, and is in theory for further research and discussion. In the country there are many electroplating workers in this area research and experiments. Pulsed plating can get high-performance coating, which is usually difficult to reach by DC plating. It can not only make the coating crystal detail, promote the grain refinement, reduce the plating porosity, but also reduce the plating
