Abstract
The effect of Potassium dichromate as inorganic inhibitor on the corrosion behavior of Reinforcing carbon steel Bars was investigated in (1 M) HCl as acidic medium at 20° C. Varied Concentrations of potassium dichromate (0.0001), (0.0004), (0.0008), (0.001) and (0.002) was investigated in study by using weight loss measurements at interval times (1-7) days and potentiodynamic polarization curves. From the result we obtain that the K2Cr2O7 have a good inhibition effect in HCl medium. Also, we obtain that the inhibition effect increases with increasing the inhibitor concentration. Inhibition efficiency was calculated for the different concentrations of potassium dichromate.
