摘要：

The inhibition effect of natural black cumin oil on the corrosion of nickel in 0.1M HCl solution was studied using galvanostatic and potentiodyanmic anodic polarization techniques. It was found that the inhibition efficiency increased with an increase in the inhibitor concentration of this oil. The inhibitive action of black cumin oil was attributed to the adsorption on metal surface. The adsorbed layer acts as a barrier between the metal surface and aggressive solution, leading to a decrease in the corrosion rate. The adsorption process follows the Langmuir adsorption isotherm. It was found also that black cumin oil provides good protection to nickel against pitting corrosion in sodium chloride solutions.
