装饰性沙丁镍镀层耐腐蚀性研究

摘要:
对导电塑料沙丁镍镀层的耐腐蚀性进行分析,通过电化学试验,分析了不同工艺的沙丁镍镀层在3.5%NaCl溶液中的腐蚀行为.结果表明:沙丁镍由于其工艺特性,镀层表面存在有机膜,膜对耐腐蚀性有一定影响,随着沙剂用量增加,沙丁镍镀层色度降低,镀层微观表面变得较粗糙,耐腐蚀性随之降低.

Abstract:
This study examined the corrosion resistance of satin nickel plating on conductive plastic.The electrochemical tests were to analyze the corrosion behavior of satin nickel plating with different processes in 3.5% NaCl solution.The results show that,because the satin nickel plating has an organic film on its surface due to process characteristics,the film results in different corrosion resistance.By increasing satin additive dosage,the nickel plating chroma decreases,the micro surface of the plating becomes rough,and the corrosion resistance is followed by decrease.
Key words:  electroplate  satin nickel plating  corrosion resistance
