摘要
本文通过L9(3~4)正交实验的设计方法.测定了数种金属在不同浓度的复合缓蚀剂中的阴阳极极化曲线.该复合缓蚀剂的组分为:苯甲酸钠、苯并三氮唑、硼砂和亚硝酸钠.随着复合缓蚀剂浓度不同的变化趋势,分析了极化曲线的特征,比较了各曲线的自然腐蚀电流i_0及自然腐蚀电位(?).
Based on orthogonal experimental design method,a series of cathodic and anodic polarization diagrams of metals in mixed corrosion inhibitors have been determined. The inhibitors consist of sodium ben-zoate, benzotriazole, borax, and sodium nitrite. According to the tendency varying with concentration of mixed inhibitors this paper analyzes the feature of polarization curves,and compares the natural corrosion current ic with corrosion potential ψ4
