| 摘 要： | 以硝酸银为主盐,磺基水杨酸为络合剂,醋酸铵和氨水为pH调节剂.研究了平均电流密度、脉冲宽度、占空比、溶液pH对镀层以及抗变色性能的影响;利用X-射线衍射分析研究了镀层结构.实验结果表明:常温下Jm=0.3 ～ 0.5 A/dm2,脉冲宽度为0.1 ～ 4 ms,占空比为5% ～ 25%,pH=8.8 ～ 9.3时,可以获得结合紧密、光亮细致的银镀层,且抗变色性能及耐腐蚀性均增强;X-射线衍射分析显示镀层主要成分是Ag.

| Abstract: | With silver nitrate as main salts,sulfosalicylic acid as complexant,ammonium acetate and ammonia as pH regulator,the effects of average current density,pulse width,duty cycle and solution acidity on electroplating property and anti-tarnish property were investigated.The structure of coating were analyzed by X-ray diffraction(XRD).The results showed that the compact,bright and uniform coating,with stronger anti-tarnish property and corrosion resistance,can be obtained under the conditions of average current ... |
