摘　　要：电流密度是电镀加工中必须控制的一个重要工艺参数,电流密度定量控制对提高产品质量和生产效率具有重要的意义。介绍了挂镀的电流密度控制方法,对通行的滚镀电流密度控制方法和科学的滚镀电流密度控制方法进行了评价,指出通行的滚镀电流密度控制方法不科学,而科学的滚镀电流密度控制方法操作难度大,2种方法均有缺陷,应根据情况修正或调整。生产中还采用一种简易的滚镀电流密度控制方法——按筒计,共同完成滚镀任务。Current density is an important process parameter that must be controlled in electroplating processing. Quantitative control of current density is of great significance to improve product quality and production efficiency. In this paper, the rack plating current density control method was introduced, and the prevailing as well as the scientific barrel plating current density control methods were evaluated. Also, it was pointed out that the prevailing barrel plating current density control method was not scientific while the scientific barrel plating current density control method was difficult to conduct, both methods were defective and should be corrected or adjusted according to the circumstances. Besides, a simple barrel plating current density control method-calculated by barrel, was also adopted in production to help to complete the plating task.
