    采用经典失重法研究了葡萄糖酸钠与硫酸锌复配在3.5%的NaClpH值为6.5的去离子水体系中对Z30铸铁的缓蚀效应.结果表明,当葡萄糖酸锌的配比浓度为0.5×10-3 mol/L0.75×10-3 mol/L,缓蚀率高达92.3%95.4%,同时借助扫描电镜、动电位实验探讨了其缓蚀机理

    Synergistic inhibition effect of(C6H11O7)Na and Zn2+ on cast iron Z30 in 3.5% NaCl was studied by the method of weight loss.The results show that the complex of(C6H11O7)Na and Zn2+ has a good synergistic inhibition effect.When the concentration of(C6H11O7)2 Zn comes to 0.5×10-3 mol/L and 0.75×10-3 mol/L,the inhibition efficiencies were 92.3%and 95.4% respectively.The mechanism of inhibition was discussed in terms of the results of polarization curves and SEMEDX.
