通过失重法、电化学方法和量子化学计算法研究了十二烷基二羟乙基氧化胺(OAE-12)在0.5mol·L~(-1)H_2SO_4中对A3钢的缓蚀性能和作用机理。结果表明,在0.5mol·L~(-1)H_2SO_4中OAE-12能同时抑制A3钢的阴、阳极反应,缓蚀性能显著,当OAE-12质量浓度仅为200mg·L-1时,失重试验所得缓蚀率可达93.59%,且失重法、动电位极化曲线法、电化学阻抗谱法测试结果具有一致性;通过量子化学计算结果可知,OAE-12缓蚀作用机理可能是源于其分子内的氮、氧与钢表面的铁的相互作用。
The corrosion inhibition properties and the effects of dodecyldihydroxyethylamine oxide (OAE-12) on A3 steel in 0.5mol·L -1 H_2SO_4 were studied by weight loss method, electrochemical method and quantum chemistry method mechanism. The results showed that OAE-12 could inhibit both anodic and cathodic reactions of A3 steel in 0.5 mol·L -1 H_2SO_4, and the corrosion inhibition performance was significant. When the concentration of OAE-12 was only 200 mg · L -1, the weight loss The corrosion inhibition rate of the experiment is up to 93.59%, and the results of weight loss method, potentiodynamic polarization curve and electrochemical impedance spectroscopy are consistent. The results of quantum chemical calculation show that the corrosion inhibition mechanism of OAE-12 may be derived from The intramolecular nitrogen, oxygen and the steel surface of the iron interaction.
