| 摘 要： | 超声波在化学镀尤其是仿金镀方面对操作参数、镀层质量作用很大,但其应用报道甚少.为了找出超声波在化学镀中的一般规律,揭示其对仿金电镀中化学镀镍及Cu2+,Zn2+和Sn2+的沉积机理,考察了超声波对仿金镀活化、化学镀镍、仿金镀电镀过程等各阶段多种因素的影响,包括活化工艺、pH值、电流密度、还原剂用量、配位剂用量等;优化了试验条件.结果显示,仿金镀工艺中引入超声波,降低了施镀的温度,提高了仿金镀的沉积速率.最后详细研究了超声波所产生的超声空化等对沉积速率、镀层质量以及仿金镀其他过程的作用机理.

| Abstract: | A new technology was developed for gold -imitation electroless plating in the presence of ultrasonic irradiation,aiming at improving the quality of the coatings and simplifying the tech-nological processes. The effects of ultrasonic wave on the activa-tion ,electroless nickel plating and copper electroplating subjected to gold-imitation electroless plating process were studied. The op-erating conditions,including deposition temperature,plating time,pH value of solutions,electric current density,concentra-ti... |
