该法既提高镀铬液的阴极电流效率又降低生产能耗，可获得光亮平滑、硬度高、结合力好的镀铬层。

It could help not only to increase the cathodic current efficiency of the chromium-plating solution, but also to obtain smooth appearance, high hardness and wearability of chromium electrodeposits.

结果表明，采用新的电镀方法能避免镀铬层裂纹的产生；并能获得表面平整光亮的镀铬层，降低表面粗糙度。

The results show that the novel method can prevent chromium coating from cracking, gain bright and smooth deposit, and reduce the surface roughness.
