INHIBITIVE INVESTIGATION OF VANILLIN ON AL ALLOY BY NOISE THECHNIQUE

Electrochemical noise and potentiodynamic polarization measurements have been used to study the corrosion behaviour of 6061 aluminium alloy in 3.5% NaCl solution with different concentration of Vanillin. Experimental data obtained have been analysed using robust statistical parameters and wavelet transform, transient shapes were also studied. The results that had been obtained from noise and tafel polarization measurements, propose 200ppm as optimum concentration to inhibit of corrosion.
