Abstract :

<p>The polyaniline, and ploy-N,N- dimethylaniline were chemically prepared in different solvents and deposited on a steel surface by cyclic voltammetric technique with different cycles. The tests for corrosion protection of the polymers coated and uncoated steel were investigated in 0.3 M NaCl solution by using Tafel polarization measurements. The experiments data showed, the studied polymers coating have ability to protect the steel against corrosion. Some factors, number of cycles of polymer preparation, solvent of polymer preparation, and the polymer type affect on the corrosion parameters, ίcorr. (corrosion current), I.E.% (inhibition efficiency), and P ( porosity) of the polymers coated steel in 0.3M NaCl solution. The all experiments were investigated at 30 0C.</p>
