运用旋转圆盘电极测定碳钢的阳极极化曲线，研究了在含Ｃｌ－的中性腐蚀介质中钨酸盐对碳钢的缓蚀机理．结果表明钨酸钠对碳钢的缓蚀作用为钝化机理，但介质中Ｍｇ２＋离子的存在对该钝化作用有显著影响．
The anodic polarization curves of carbon steel were measured by rotating disk electrode. The corrosion inhibition mechanism of tungstate on carbon steel was investigated in a Cl- -contacting neutral medium. The results show that the corrosion inhibition mechanism of sodium tungstate on carbon steel is a passivation mechanism, but the presence of Mg2 + ions in the medium has a significant effect on the passivation effect.
