中文摘要: 研究了纯银制品分别采用铬酸盐化学钝化和有机物化学钝化等不同工艺处理后的抗含硫物腐蚀效果。采用硫化铵溶液进行防腐试验。结果表明,重铬酸钾加硝酸或冰醋酸的处理方法有很好的抗腐蚀效果。
Abstract:The silver craftwork's anti-sulphur corrosion is studied after treated by chromate passivation process and organic passivation process, the ammonium sulphide solution is used as sulphur medium. The results show that the potassium bichromate plus nitric acid or glacial acetic acid has the best anti-corrosion effect.
