【摘要】 研究了盐酸腐蚀低碳钢（ ｗ（ Ｃ） 为０２２ ％ ） 的反应动力学．采用比色法分析了低碳钢在不同的温度和不同浓度盐酸中的腐蚀速率，确定了动力学方程及其参数， 并测定了在系统中加入缓蚀剂 Ａ Ｓ 的最佳质量浓度． 结果表明： 在２５℃，当ｃ（ Ｈ Ｃｌ） 大于５００ ｍｏｌ·ｄ ｍ － ３ 时，腐蚀反应呈匀速进行，且速率明显增大；缓蚀剂 Ａ Ｓ 的最佳质量浓度为０ ．２０ ｇ·ｄ ｍ － ３ ；动力学参数 ｋ 是低碳钢在ｃ（ Ｈ Ｃｌ） 趋于零时的腐蚀速率， Ｂ 值反映了腐蚀速率随ｃ（ Ｈ Ｃｌ） 改变而变化的幅度．更多还原

【Abstract】 Studies on the kinetics of corrosion of low carbon steel ( w (C)=0.22%) have been carried out. The kinetic equation has been established based on the corrosion rates of low carbon steel obtained using colorimetric method at several temperatures and HCl concentrations. The optimum AS concentration for inhibition of corrosion has also been investigated. The results showed that corrosion rate increases steadily with the increasing of concentration of HCl while c(HCl) is over 5.0 mol·dm -3 . The optimum AS content in solution is 0.20 g·dm -3 . Parameter k is the corrosion rate when c (HCl) goes towards 0, and parameter B is the amount of increasing as c (HCl) rises in a unit.更多还原
