Abstract

In this investigation, the corrosion study was conducted on fiber laser welded joints of AISI 410 and 316L stainless steel plates using hydrochloric acid, basic, and salt medium, behavior in three different pH. The effects of three different corrosive atmospheres were examined using the weight loss method. The test sample which was exposed to 1 N hydrochloric acid medium for 48 Hours resulted in 0.006 g of weight loss. The maximum amount of corrosion was found in the acidic medium whereas the least was observed in the salt medium. The effectiveness of three distinct derivatives of 1H-indole-2,3-dione, each replaced with hydroxyl groups in various positions, in inhibiting corrosion. Among the three derivatives examined, it was observed that those with ortho and para hydroxyl group substitutions exhibited superior inhibitory properties.

AISI 316 与 AISI 410 光纤激光焊接接头的腐蚀和抑制研究

在这项研究中，使用盐酸、碱性和盐介质对 AISI 410 和 316L 不锈钢板的光纤激光焊接接头进行了腐蚀研究。使用失重法检测了三种不同腐蚀环境的影响。在 1 N 盐酸介质中暴露 48 小时的测试样品的重量损失为 0.006 克。酸性介质中的腐蚀量最大，而盐性介质中的腐蚀量最小。1H -吲哚-2,3-二酮的三种不同衍生物（每种衍生物在不同位置都被羟基取代）在抑制腐蚀方面的效果。在所研究的三种衍生物中，正羟基和对羟基取代的衍生物表现出更优越的抑制特性。关键词：光纤激光焊接、移动速度、腐蚀研究、Isatin 希夫碱、抑制剂 Bull.Chem.Soc.2024, 38(3), 811-823.

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.
