摘要: 采用硫华气相腐蚀实验、紫外光曝露加速腐蚀实验和电化学极化曲线法对PMTA(1-巯基-5-苯基四氮唑)、MBO(2-巯基苯并恶唑)、MBI(2-巯基苯并咪唑) 、复配缓蚀剂PMM的防银变色作用进行了比较和研究，结果表明，PMM防银变色性能最好，显示出协同效应.防变色膜的AES和XPS研究结果表明，PMM在银表面上所形成的防变色膜比单组分缓蚀剂防变色膜致密且稳定，从而能够更有效地防银变色.

Abstract：By means of corrosion test of flower of sulfur vapo r,corrosion test under ultraviolet photallochromy acceleration and measurement o f polarization curve,the inhibition performance of 1-phenyl-5-mercaptotetrazole (PMTA),2-mercaptobenzoxazole (MBO),2-mercaptobenzimidazole (MBI) and the built i nhibitor (PMM) were evaluated.The result of corrosion test showed that PMM was t he most prominent for silver in the four inhibitors and the PMM took on the syne rgistic effect.The anti-tarnishing films were studied by the means of Auger elec tron spectroscopy (AES) and X-ray photoemission spectroscopy (XPS).Results showe d that the anti-tarnishing film formed by PMM is more compact and stabilized tha n that of mono-component inhibitor,so the mixed tarnishing inhibitor was more ef fective than mono-component inhibitor.

Key words： silver anti-tarnishing film PMM
