dc.descriptionThe effect of potassium chromate (K2CrO4) compound on the inhibitive performance of type A513 mild steel was studied using linear and open circuit polarization technique with μAutolab PGstat101. The structural degradation tendency was observed with high resolution optical microscope. Data obtained from Tafel plot showed that the organic compound performed effectively in acid/chloride solution at all concentration of (K2CrO4) with average inhibitor efficiency above 60%. The outcome of the OCP showed a significant correlation with the LPR trend. The massive influence of the inhibitive compound on steel was seen as a chemisorption mechanism in which the corrosive anions and particulate were supressed significantly. The adsorption of the compound was determined and was found to obey the Langmuir isotherm model. The structural properties generally were affected with high aggressiveness of the acid/chloride ion mix with uniform corrosion propagation observed along the entire interface.
