一、前言长期以来,人们大都着眼于改变镀液成份,采用添加剂,移动阴极等方式来改善镀层性能和获取功能性镀层。随着电子电力学的不断进步,各种不同用途波形各异的电源相继问世。电镀工作者从六十年代中期把脉冲电源引入电镀领域试图提高电镀速度。虽 For a long time, most people focus on changing the composition of the bath, using additives, such as moving the cathode to improve the coating performance and access to functional coatings. With the continuous progress of electronic electrodynamics, a variety of different uses of wave power have come out. Electroplating workers introduced pulsed power into the electroplating field from the mid-1960s in an attempt to increase plating speed. although
