摘要
研究了1-苯基-5-巯基四氮唑(PMTA)对青铜的缓蚀性能。经盐水浸泡试验和电化学测试证明,用 PMTA 处理过的青铜片抗 Cl^-腐蚀性能较好。电子能谱分析(AES 和 XPS)表明 PMTA 与青铜合金元素配位较大,因此推测 Cu_2O、SnO_2、PbO 等相互作用而形成复杂的络合物膜起了保护作用。
The inhibiting action of PMTA for bronze is investigated in this paper.It is proved more effective resistance to chloride to make corrosion test and to determine the electrochemical test in salt water(3. 5% NaCl).It is possible formed complex between the elements of bronze and PMTA,that drawn an inference from AES and XPS.The PMTA with Cu_2O,ShO_2 or Pbo interacted each other and may be formed a complex protective film.
