The degradation of metallic materials under the effect of the environment is defined as a corrosion process. Under the aggressive environment, corrosion leads to the formation of corrosion products. The use of inhibitor substance is considered as one way to protect the metal surface against corrosion. The inhibitor is chemically adsorbed py the surface of the metal and forms a protective thin film with inhibitor effect. The protection can also be achieved by a combination of inhibitor ions and metallic surface. The current work was evaluated using corrosion inhabitation of carbon steel in NaCl solution by carbimazole\Zn system. The ability of carbomazole as a good corrosion inhibitor is enhanced by the presence of Zn+2 when the concentration of carbomazole increased and this may be attributed to the protective film formed on the metal surface was withstand the continuous attack of corrosive ions. Also, the formation of complex Fe-carbomizole/Zn+2 linkages on the anodic sites of the metal surface during the immersion time may play a role in the improvement in adsorption of inhibiter system via coverage more area of the metal surface which reduced the exposure of anode sites to the corrosive media. By using Langmuir isotherm model to identify the inhibitor mechanism performance, the values of linear correlation coefficient were close to (1) suggested that the adsorption of the studied inhibitors follows Langmuir isotherm model. Generally, values of ΔGads up to -9.7 kJ/mol are attributed to the electrostatic interaction between the inhibitor molecules and the metal surface (physical adsorption), whilst those at -10.6 kJ/mol or a little more negative are consistent with chemical bonding of the inhibitor to the sample (Chemisorption).
