摘要
采用电化学方法,通过测定孔蚀电位、诱导期和阴、阳极极化曲线,分析了复合缓蚀剂ZnBTA在中性高Cl^-水介质中对铝合金的缓蚀性能及缓蚀作用类型。实验表明:ZnBTA可显著阻滞孔蚀的诱发和发展;对电极阴、阳极过程均有明显抑制作用,具有混合抑制型缓蚀剂的特征。
The corrosion inhibtion properties and action forms of ZnBTA compound inhibitors for aluminum alloys in the neutral solution of high CL^- concentration were studied by determing the pitting corrosion potential, incubation period and anodic, cathodic polorization curves with elctrochemical methods. The results show that ZnBTA has the characteristics of combined anodic and cathodic inhibitors for it can remarkablly inhibit the initiation and growing of pitting corrosion and the anodic and cathodic process. The inhibition mechanism is also discussed.
