چکیده
Abstract The corrosion inhibition of cow bone soot (BAS) at 5%, 10%, 15% and 20% weight on low carbon steel (LCS) in artificial concrete pore solution was evaluated with potentiodynamic polarization current-time displacement. BAS visibly decreased the rate LCS from 7.31 x 10 2 mm/y 0% to 1.45 concentration. Maximum performance 80.18% obtained mechanism determined be anodic type. Cathodic reduction plot significant due decrease O adsorption. Plot current versus time shows reduces thermodynamic tendency corrode.
