| 摘 要： | 采用动电势扫描法测定了碳钢在饱和（NH4）2CO3溶液中的阳极极化曲线，研究了几种缓蚀剂与表面活性剂复配后的协同缓蚀作用。结果表明：体系中添加0．1％的四西基碘化铵，缓蚀效率为55．3％； 当0．05％的四西基碘化铵与0．05％十二烷基硫酸钠复配时，协同缓蚀效率可达89．2％。应用动电势扫描法能够快速、简便地测定腐蚀速率和评选缓蚀剂。

| Abstract: | The anode polarization curves of 45 # carbon steel in the solution of saturated(NH 4) 2CO 3 were determined using potentodynamic scanning method.Inhibition and synegistic inhibition effect of the several surface active agent and inhibitor were discussed.The conclusion is that adding 0.1% of the (C 4H 9) 4NI in the system,the inhibiting efficiency is 55.3%.As 0.05% (C 4H 9) 4NI and 0.05% C 12 H 25 OSO 3Na sifting,the inhibiting efficiency is 89.2%.The potentodynamic scanning method can determine the corrosion rate and screened inhibitor quickly and simply. |
