摘要
以氨基磺酸钴和钨酸钠为主盐、以柠檬酸盐为络合剂组成电沉积钴钨合金的镀液 ,研究镀液中NH+ 4 的浓度、Co2 + 离子的络合比、溶液热处理等对镀液性能的影响。结果表明 :在实验条件下 ,以柠檬酸盐为络合剂的钴钨合金镀液中 ,NH+ 4 可以提高镀液稳定性和镀层含钨量 ;添加络合剂及镀液在 80～
The solution composition for cobalt tungsten deposition is: cobalt sulphamate and sodium tungstate as the main salts, citrate as the complexing agent. The effects of ammonium concentration, the complex ratio of the Co 2+ ion and solution heat treatment on the solution behavior are studied in this paper. Under the given experiment conditions, the results show that NH + 4 and complexing agent can change the alloy film composition, improve solution stability and deposition appearance, and that heat treatment at the temperature of 80℃～90℃ can improve the solution behavior and increase the current efficiency.
