摘要:

采用失重实验、电化学实验、表面形貌测试 (SEM、AFM) 和接触角测试深入研究了0.10 mol/L 三氯乙酸 (Cl₃CCOOH) 介质中非离子表面活性剂椰油酸二乙醇酰胺 (CDEA) 对冷轧钢的缓蚀作用；并探究了缓蚀溶液的表面张力和电导率与缓蚀性能的内在关联。结果表明：CDEA对冷轧钢在Cl₃CCOOH中有明显的腐蚀抑制作用，20和30 ℃下，CDEA浓度仅为20 mg/L时，缓蚀率可高达95%以上。缓蚀性能随CDEA浓度增大而增强，但随温度的上升而减弱。CDEA在钢表面的吸附是符合Langmuir吸附的、自发的、放热的过程，20~50 ℃下标准吸附Gibbs自由能为-33.6~-33.0 kJ/mol。CDEA为既抑制阴极析氢又抑制阳极溶解的混合型缓蚀剂，其缓蚀机理为“几何覆盖效应”。随CDEA的添加，Nyquist图容抗弧增大，且电荷转移电阻增大。SEM和AFM的微观形貌进一步证实了CDEA显著抑制了Cl₃CCOOH溶液对冷轧钢表面的腐蚀。缓蚀钢表面呈现较强的疏水性，其接触角为100.66^o。溶液表面张力随CDEA的添加而降低，在钢片浸泡后的溶液表面张力较浸泡前有所增加；溶液电导率随CDEA浓度的增加，在50 mg/L附近出现峰值。

Abstract：

The corrosion inhibition effect of nonionic surfactant coconut oleic acid diethanolamide (CDEA) on a cold rolled steel in 0.10 mol/L trichloroacetic acid (Cl₃CCOOH) solution was studied by mass loss method, electrochemical test, surface morphology characterization (SEM and AFM) and contact angle tester，while the relation of the inhibition performance of CDEA with the surface tension and electrical conductivity of its solution was also studied.The results show that CDEA has obvious corrosion inhibition effect on CRS in Cl₃CCOOH solution. The corrosion inhibition efficiency can reach as high as 95% for the CRS corrosion at 20 and 30 ℃ with the CDEA dose of only 20 mg/L. The corrosion inhibition performance increase with the increasing CDEA concentration, but decreases with the rising temperature. The adsorption of CDEA on the CRS surface is in accordance with the Langmuir adsorption, a spontaneous and exothermic process, and the standard free energy of Gibbs adsorption is -33.6--33.0 kJ/mol at 20-50 ℃. CDEA is a mixed corrosion inhibitor that inhibits both the cathodic hydrogen evolution and anodic dissolution, and the corrosion inhibition mechanism is "geometric coverage effect". With the addition of CDEA, the capacitive arc of Nyquist diagram is enlarged, and the charge transference increased. SEM and AFM micrographs further confirm that CDEA significantly inhibited the corrosion of CRS surface in Cl₃CCOOH solution. Being treated by CDEA inhibitor, the surface of CRS shows strong hydrophobicity with a water contact angle of 100.66°. The surface tension of the solution decreased with the addition of CDEA, however after immersion test of the steel, the surface tension of the solution with CDEA turned to be higher, in the contrast to the original ones. the electrical conductivity of the solution increases with the concentration of CDEA and reached a peak near 50mg/L.

Key words： inhibition coconut oleic acid diethanolamide steel trichloroacetic acid adsorption
