摘要： 化学镀镍磷合金具有耐蚀性、可焊性、厚度均匀和硬度高等优点.已得到广泛应用.为提高生产效率,超高速化学镀镍成为人们关注的新课题,采用沉积速度达23～27μm/h,以满足机械、电子、化工和印刷等对较厚化学镀镍层的要求.

关键词: 化学镀镍, Ni0P合金, 加速剂, 硫脲

Abstract: The effect of organic sulfur accelerator on the deposition rate of chemical nickel-plating and on the oxidation rate of sodium hypophosphite was studied.It is found that theacceleration mechanism is due to the catalytic action of accelerator for the oxidation of hy-pophosphite, The results of XPS Indicate that the coating is composed of Ni and Ni2P alloy.The composition (relative atomic concentration %)of the Ni-P coating are Ni 74.3%,P 18.3%,O 5.8% and S 1.6% as obtained from the AES depth profile ctirves.

Key words: chemical nickel-plating, Ni-P alloy, accelerator, thiourea
