Abstract

The high toxicity of industrial metal corrosion inhibitors raises various environmental and health problems. Thus, the study of metals and alloys corrosion inhibition, in acidic media, by eco-compatible organic compounds, has become a very attractive research field. In this paper, garlic ( Allium Sativum ) extract inhibition efficiency (IE) against API X60 carbon steel (CS) and 316L stainless steel (SS) corrosion, in a 1 M sulphuric acid (H 2 SO 4 ) solution, has been investigated using electrochemical techniques, including potentiodynamic polarization (PPD) and electrochemical impedance spectroscopy (EIS). The experimental results showed the remarkable corrosion inhibitive performance of garlic extract (GE). The corrosion IE, which depends on the inhibitor concentration, increased up to 90%, for SS, and 67% for CS, as shown from the PPD tests. EIS analysis showed that the corrosion resistance (CRST) was increased in the medium with GE, indicating the properties improvement of the passive films formed on the steels surfaces.

大蒜提取物作为API X60碳钢和316L不锈钢在硫酸中的环境缓蚀剂

工业金属缓蚀剂的高毒性引起了各种环境和健康问题。因此，研究生态相容性有机化合物在酸性介质中对金属和合金的缓蚀作用已成为一个非常有吸引力的研究领域。本文利用电化学技术，包括动电位极化(PPD)和电化学阻抗谱(EIS)，研究了大蒜(Allium Sativum)提取物在1 M硫酸(h2so4)溶液中对API X60碳钢(CS)和316L不锈钢(SS)的缓蚀效果(IE)。实验结果表明，大蒜提取物(GE)具有显著的缓蚀性能。从PPD测试中可以看出，腐蚀IE(取决于缓蚀剂浓度)在SS中增加了90%，在CS中增加了67%。EIS分析表明，在GE介质中，钢的耐蚀性(CRST)提高，表明钢表面形成的钝化膜的性能得到改善。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
