【摘要】 采用静态挂片法研究苯并三氮唑（BTA）对碳钢在 LiBr 溶液中腐蚀的影响,利用极化曲线探讨其缓蚀作用的机理.实验表明 BTA 对碳钢在 LiBr 溶液中有一定的缓蚀作用,其中添加0.020 mol·L^-1BTA 和0.20 mol·L^-1 LiOH 能显著抑制 LiBr 溶液对碳钢的腐蚀。BTA 可能是在碳钢表面形成一层 Fe-BTA 吸附膜,阻滞阳极反应从而起到缓蚀作用。更多还原

【Abstract】 The effect of benzotriazole to corrosion of carbon steel in lithium bromide solution by the way of weigh loss is studied in the ar- ticle.It reveals that benzotriazole exists inhibition to the carbon steel in the lithium bromide,it decreases effectively the corrosion of the lithium bromide to the carbon steel by adding 0.20 mol·L^-1 lithium hydroxide and 0.02 mol·L^-1 benzotriazole.It assumed that the com- plea film of Fe-BTA formed on the carbon steel decrease the corrosion through inhibition of anodic reaction.更多还原
