Abstract
Corrosion inhibition of martensitic stainless steel (MSS) in magnesium chloride was investigated in the absence and presence of calcium gluconate as corrosion inhibitor at ambient temperature. The effects of inhibitor concentration were studied using weight loss and polarization method. The results obtained showed that calcium gluconate acts as an inhibitor for martensitic stainless steel in MgCl and decreases the corrosion rate. The inhibition performance was found to increase with the increase in inhibitor concentration. The maximum inhibition efficiency obtained was 99 % at 2g/v inhibitor concentration, the adsorption of calcium gluconate on the surface of Martensitic stainless steel was found to obey Langmuir adsorption isotherm. However, the addition of solanum tuberosum extract in the inhibitor decreases the corrosion rate of martesitic steel significantly in chloride solution.
