Abstract

The inhibition impact of 5-((thiophen-2-ylmethylene)amino)-2-mercapto-1, 3, 4-thiadiazole (TMT) on mild steel corrosion in 1.0 M HCl have been Investigated. The weight loss and Scanning electron microscopy techniques were utilized in order to estimate inhibition efficiency of TMT as immersion time function. TMT shows an excellent inhibition impact in corrosive solution on mild steel. The excellent efficiency was due to the active sites blocking which were done through adsorption of MTM molecules on the steel surface. The inhibition efficiency decreases with increasing temperature.
