开发了一种新型镀铬工艺 .在 45A/dm2 的电流密度下 ,阴极电流效率达 2 6 % .新型复合型镀铬添加剂的加入 ,提高了阴极电流效率及镀液的覆盖能力 ,改善了镀层的性能 ,并在较宽的电流密度范围内可获得光亮的镀层 .
The new chromium electrodeposition process with high cathode efficiency was developed successfully, with which the cathode efficiency can be more than 26%(45 A/dm2). The addition of the new chromium electrodeposition additives can increase the cathode efficrency, improve the covering ability of the solution as well as the quality of the depositions.
