The purpose of the present study is to develop an understanding of how iron carbide layers, derived from the different microstructures of carbon steels during corrosion, affect corrosion behavior and inhibitor performance. The applications of this study in industry are numerous. Many types of mild steel are used in the construction of pipeline transmission systems. Compared to the use of corrosion resistant materials, corrosion inhibitors used in combination with carbon steel can be an economic alternative for corrosion mitigation in oil and gas pipelines. Therefore, such research that sheds...
