摘要: 研究了钨系水处理剂复合配方对碳钢在含Cl~-及SO_4~(2-)水中的缓蚀作用,筛选出最佳复配方案。根据电化学测试和XPS分析结果探讨了钨系水处理剂的缓蚀机理。

Abstract：To determine the suitability of inhibitors containing WO_4~(2-), many tests based on orthogonal design methods are studied using polarization and weight-loss technique. Optimum results show that inhibitors containing WO_4~(2-) are suitable under various conditions. By adding inhibitors, the corrosion rate of mild steel is below 0.1 mpy in the presence of high concentration of Cl and SO_4~(2-) ions (Cl~-+SO_4~(2-)=5, 000ppm). BASIC programs on IBM PC are designed. The integral average value of polarization resistance is calculated using the programs. Scanning potentiodynamic technique describes corrosion on mild steel and inhibitors' behavior in Cl~- and SO_4~(2-) environment. The film on iron exposed to inhibitors have been studied using XPS and Ar~+ ion sputtering. Correlation are found between protective quality and film composition.
