CrCl3对酸性化学镀Ni-Cu-P镀液镀层性能的影响
Shanghai Jiaotong Daxue Xuebao/Journal of Shanghai Jiaotong University(2003)
Abstract
研究了CrCl3对酸性化学镀镍铜磷合金溶液的稳定性、沉积速度以及镀层成分、表面断面形貌的影响,并与文献报道的其他Ni-Cu-P镀液的稳定剂进行了比较.结果表明:CrCl3能有效地抑制镍铜磷镀液的分解和铜在基体上的置换反应,得到更高铜含量的光亮镀层;随着CrCl3在镀液中含量的增加,沉积速度先升后降;CrCl3的加入使镀层中铜含量略微降低,镍磷含量增加;与其他稳定剂一样,CrCl3不改变沉积层的岛状表面形貌;断面形貌表明镀层仍保持致密.
