提高电镀硬铬镀层与基体金属结合力的方法

Methods of improving the adhesion between hard chromium plating and base metal

本文通过在电镀硬铬生产实践中经常出现硬铬镀层与基体金属结合力的问题,研究了影响硬铬镀层与基体金属结合力的因素。优化了电镀硬铬的操作工艺和增加了电镀硬铬特殊操作方法。结果表明,通过优化操作工艺和增加了电镀硬铬特殊操作方法,硬铬镀层的各项指标达到了一个最佳的数值范围,使电镀硬铬镀层与基体金属结合力的合格率达到了96%以上。

In this paper,the bonding force between hard chromium coating and base metal is often found in the production practice of hard chromium electroplating.The factors affecting the adhesion between hard chromium coating and base metal were studied.The operation process of hard chromium electroplating was optimized and the special operation method of hard chromium electroplating was added.The results show that:By optimizing the operation process and adding a special operation method for electroplating hard chromium,all the indexes of the coating have reached an optimum value range.The qualified rate of adhesion between hard chromium plating and base metal is over 96%.
