%X The corrosion inhibition e®ect of synthesized 1,3-benzothiazole at very low concentrations on 410  martensitic stainless steel in 3MH2SO4 solution was studied through potentiodynamic polarization  and weight loss measurements. The observation showed that the organic compound performed  e®ectively with average inhibition e±ciencies of 94% and 98% at the concentrations studied from  both electrochemical methods due to the inhibition action of protonated inhibitor molecules in the  acid solution. The amine and aromatics functional groups of the molecules active in the corrosion  inhibition reaction were exposed from Attenuated total re°ectance-Fourier transform infrared  spectroscopy (ATR-FTIR) spectroscopic analysis. Thermodynamic calculations showed cationic  adsorption to be chemisorption adsorption, obeying the Langmuir adsorption isotherm. Images from  optical microscopy showed an improved morphology in comparison to images from corroded  stainless steel. Severe surface deterioration and macro-pits were observed in the uninhibited samples.
