In order to investigate the electrochemical corrosion behavior of hydrogen chloride diaphragm pump membranes in high-chloride and high-temperature hydrogen chloride environments, Tafel polarization method and Electrochemical Impedance Spectroscopy (EIS) were employed to analyze the corrosion resistance of the membranes. The corrosion samples of the membranes under different operating conditions were analyzed by SEM, EDS, and XPS testing methods. The results indicate that 301L stainless steel membranes suffer severe corrosion in hydrogen chloride environments, with no stable passivation region observed in the polarization curves. With increasing solution concentration and temperature, the self-corrosion current density increases, leading to a decrease in corrosion resistance. The stainless steel membranes exhibit high sensitivity to temperature. The charge transfer resistance in a 90 ℃ HCl solution environment is 3.682, which is only 6.7% of that at 50 ℃. The corrosion current density is 1.258×10-2 A/cm2, which is 3.94 times that at 50 ℃, and the ion diffusion rate accelerates. Competition for Cl- adsorption makes it difficult for oxides in the corrosion products to maintain stability, hindering the formation of a passive film on the surface, thus leading to the occurrence of pitting corrosion in stainless steel. These findings provide a basis and reference for the study and design of corrosion-resistant membranes for diaphragm pumps.

为了研究氯化氢隔膜泵膜片在高氯、高温氯化氢环境中的电化学腐蚀行为,采用Tafel极化法和电化学阻抗法(EIS)分析膜片的耐蚀性能,并利用SEM,EDS,XPS测试方法,对不同工况下的膜片腐蚀样品进行分析。结果表明,301L不锈钢膜片在HCl环境中腐蚀严重,极化曲线均没有稳定的钝化区,随着溶液浓度及温度的提升,自腐蚀电流密度增大,耐蚀性能下降;不锈钢膜片对温度表现出较高的敏感性,90 ℃ HCl溶液环境下的电荷转移电阻为3.682,仅为50 ℃时的6.7%,腐蚀电流密度为1.258×10-2 A/cm2,是50 ℃时的3.94倍,离子扩散速率加快;Cl-的竞争吸附使腐蚀产物中的氧化物难以维持稳定,表面难以形成钝化膜,容易导致不锈钢点蚀的发生。研究结果可为隔膜泵膜片耐腐蚀研究和设计提供依据和参考。

为了研究氯化氢隔膜泵膜片在高氯、高温氯化氢环境中的电化学腐蚀行为,采用Tafel极化法和电化学阻抗法(EIS)分析膜片的耐蚀性能,并利用SEM,EDS,XPS测试方法,对不同工况下的膜片腐蚀样品进行分析。结果表明,301L不锈钢膜片在HCl环境中腐蚀严重,极化曲线均没有稳定的钝化区,随着溶液浓度及温度的提升,自腐蚀电流密度增大,耐蚀性能下降;不锈钢膜片对温度表现出较高的敏感性,90 ℃ HCl溶液环境下的电荷转移电阻为3.682,仅为50 ℃时的6.7%,腐蚀电流密度为1.258×10-2 A/cm2,是50 ℃时的3.94倍,离子扩散速率加快;Cl-的竞争吸附使腐蚀产物中的氧化物难以维持稳定,表面难以形成钝化膜,容易导致不锈钢点蚀的发生。研究结果可为隔膜泵膜片耐腐蚀研究和设计提供依据和参考。

In order to investigate the electrochemical corrosion behavior of hydrogen chloride diaphragm pump membranes in high-chloride and high-temperature hydrogen chloride environments, Tafel polarization method and Electrochemical Impedance Spectroscopy (EIS) were employed to analyze the corrosion resistance of the membranes. The corrosion samples of the membranes under different operating conditions were analyzed by SEM, EDS, and XPS testing methods. The results indicate that 301L stainless steel membranes suffer severe corrosion in hydrogen chloride environments, with no stable passivation region observed in the polarization curves. With increasing solution concentration and temperature, the self-corrosion current density increases, leading to a decrease in corrosion resistance. The stainless steel membranes exhibit high sensitivity to temperature. The charge transfer resistance in a 90 ℃ HCl solution environment is 3.682, which is only 6.7% of that at 50 ℃. The corrosion current density is 1.258×10-2 A/cm2, which is 3.94 times that at 50 ℃, and the ion diffusion rate accelerates. Competition for Cl- adsorption makes it difficult for oxides in the corrosion products to maintain stability, hindering the formation of a passive film on the surface, thus leading to the occurrence of pitting corrosion in stainless steel. These findings provide a basis and reference for the study and design of corrosion-resistant membranes for diaphragm pumps.
