Synthetic Organic Molecules as Metallic Corrosion Inhibitors: General Aspects and Trends

Abstract

Organic molecules are gaining special attention over the last years in the corrosion area thanks to their general low achievable cytotoxicity, structural versatility, and environmentally friendly obtainment methods. Under those approaches, synthetic organic motifs have attracted the interest of researchers due to their variated methods of obtention through molecular manipulation via diverse chemical reactions, allowing the production of adequately planned structures or repurposing their original application in the case of drugs. This review summarizes general aspects that are desired in organic molecules as corrosion inhibitors, presenting selected works published in the 2022–2023 period and emphasizing the importance of finding novel and different organic corrosion inhibitors. Patents were not considered in this review. Scifinder, Google Scholar, and Web of Science were employed as databases. Mathematical and analytical methods involved in the search for corrosion inhibitors are out of this review’s scope.

Comparison of Friction Properties of GI Steel Plates with Various Surface Treatments

“…The dry lubricant on the steel plates should meet the requirement of eliminating coating flaking and the need for additional oil, thus keeping the forming presses (the contact surfaces of the blank holder, punch and die) clean and ready for the next step of production [21]. A typical permanent coating consists of a coating-forming material (resin) and different types of additives (forming additives and corrosion inhibitors) [22][23][24] enhancing conductivity and/or corrosion protection [25].…”
