The existence of cracks in reinforced concrete and the penetration of corrosive agents increase the risk of pitting attacks in steel rods. In this paper, inhabitation efficiency and the ability to control the pitting by TEA and DEA organic inhibitors by electrochemical
measurements, was studied. The results show that TEA in 0.4 \% vol. and DEA in 0.2 \% vol. are in an optimum inhibition condition. The lower inhabitation efficiency, with low stability in a double layer in the simulation model for DEA, concluded that this inhibitor
can not protect steel from pitting corrosion such as TEA in concrete environments.
