Abstract

DBS corrosion resistance effect on MS immersed in a 0.25 mol/L sulphuric acid (H 2 SO 4 ) solution has been evaluated at room temperature, using WL method, from which CR and IE(%) were obtained. The corrosion IE% increased with higher inhibitor concentrations. The CR decreased with higher DBS concentrations, since it blocked the MS active site, forming a protective film on its surface, which was confirmed by electrochemical studies and surface analysis techniques, such as FTIR and SEM. EDAX was used to analyze the elements present on the MS surface, after its immersion in 0.25 mol/L H 2 SO 4 , without and with DBD. The MS surface smoothness and roughness (polished and corroded) and the inhibitor have been evaluated by SEM and AFM

硫化二丁酯对低碳钢在硫酸介质中的耐蚀性、电化学和表面形貌的研究

在室温条件下，用WL法测定了MS在0.25 mol/L硫酸(h2so4)溶液中的耐蚀性能，得到了CR和IE(%)。缓蚀剂浓度越高，腐蚀IE%越高。DBS浓度越高，CR越低，这是因为DBS阻断了MS活性位点，在其表面形成了一层保护膜，电化学研究和表面分析技术(如FTIR和SEM)证实了这一点。在0.25 mol/L h2so4中浸泡，不加DBD和加DBD后，用EDAX分析质谱表面存在的元素。用SEM和AFM对MS表面的光滑度和粗糙度(抛光和腐蚀)以及抑制剂进行了评价

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.
