研究了以硫代硫酸钠和硝酸银为主盐的体系时,电流密度对镀层表面形貌、结合力和镀层物相的影响。结果表明:在该体系中电流密度为0.1、0.2A/dm~2时,制备的镀层表面光亮平整、镀层结合力良好、电流效率高、镀层质量优异。
The effects of current density on the surface morphology, cohesion and the phase of the coating were studied when the system consisted of sodium thiosulfate and silver nitrate as the main salt. The results show that when the current density is 0.1 and 0.2 A / dm ~ 2 in the system, the surface of the prepared coating is bright and smooth, the bonding force of the coating is good, the current efficiency is high, and the quality of the coating is excellent.
