摘要
在银表面分别用1-苯基-5-巯基四氮唑乙醇溶液和十六硫醇乙醇溶液制备了防银变色保护膜。采用硫化氢腐蚀试验和极化曲线、交流阻抗及循环伏安等电化学方法测试。对防变色性能进行了比较。结果表明,十六硫醇乙醇溶液对银的防变色效果优于1-苯基-5-巯基四氮唑乙醇溶液。
The protective coatings on silver surface were prepared by using l-Phenyl-1H-tetrazole-5-thiol（PMTA） ethanol solution and hexadecane-thiol（HDT） ethanol solution respectively.The tarnish prevention performances were compared through H_2S accelerating tarnish test,polarization curve,AC impedance and cyclic voltammetry methods.The results showed that the tarnish prevention performance of HDT was better than that of PMTA.
