摘要
本研究的目的是利用电化学和重量测量技术研究 DBSS 在 35 °C 的 0.5 M 硫酸溶液中对热处理双相 AISI 1040 钢腐蚀的抑制作用。腐蚀研究是通过电位极化研究(PDP)、电化学阻抗研究(EIS)和重量法进行的。为了确认抑制效果,还进行了 X 射线衍射技术(XRD)分析、扫描电子显微镜(SEM)和 EDS 分析等表面表征。根据热处理导致的金属相变,在十二烷基苯磺酸钠盐(DBSS)抑制剂存在的情况下,将热处理金属暴露在 35 °C 的 0.5 M H2SO4 中,其缓蚀效果会增加。在正火、700 ℃淬火、750 ℃淬火、790 ℃淬火和 900 ℃淬火的热处理条件下,AISI 1040 钢的最高抑制效率分别为 63%、82%、87%、43% 和 63%。在重量分析和电化学研究中,750 ℃淬火和 790 ℃淬火的 IE 随 DBSS 浓度的增加而增加,重量分析结果分别为 75% 和 87%。通过热处理工艺和使用 DBSS 作为抑制剂,都能实现对金属的保护。扫描电镜和 XRD 证实了金属表面的缓蚀效果。此外,DBSS 在金属表面阳极和阴极位点的吸附情况也得到了很好的解释。
Sodium salt of dodecyl benzene sulphonic acid as an effective corrosion inhibition for different heat-treated steel in sulphuric acid medium
The purpose of this work is to use electrochemical and gravimetric techniques to investigate the inhibition of DBSS on the corrosion of heat-treated dual-phase AISI 1040 steel in a 0.5 M sulphuric acid solution at 35 °C. The corrosion studies are performed by potentiodynamic polarization study (PDP), electrochemical impedance study (EIS), and gravimetric method. To confirm the inhibition surface characterization like x-ray diffraction technique (XRD) analysis, scanning electron microscopy (SEM), and EDS analysis are performed. Depending on the phase change of metals due to heat treatment, the corrosion inhibition of the heat-treated metal increased when it was exposed to 0.5 M H2SO4 at 35 °C in the presence of dodecyl benzene sulphonic acid sodium salt (DBSS) inhibitor. The highest inhibition efficiency of 63%, 82%, 87%, 43%, and 63% was obtained for AISI 1040 steel at heat treatment conditions of Normalized, Quenched at 700 °C, Quenched at 750 °C, Quenched at 790 °C and Quenched at 900 °C respectively. In the gravimetric and electrochemical study, the IE increases with the increase with the concentration of DBSS unto 75% from gravimetric analysis and 87% from PDP analysis for Quenched at 750 °C and 790 °C respectively. The metal protection is achieved by heat treatment process as well as by using DBSS as inhibitor. Corrosion inhibition on the metal’s surface was confirmed by SEM and XRD. In addition, the adsorption of DBSS on the anodic and cathodic sites of the metal surface was well explained.
