MS corrosion behavior was herein studied via green azo methane, i.e., BDTT, in a 0.5 M H2SO4 solution.CI mechanisms were investigated by Ec techniques (PDP, EIS and WL).Experimental studies results were supplemented with theoretical calculations, DFT and various Td adsorption and activation parameters.BDTT molecule mechanism of adsorption onto the MS surface followed Langmuir's isotherm.In this study, an eco-friendly and cost-effective strategy to hinder corrosion was proposed.
