| Abstract: |
The inhibitive effects of the aqueous extract of Domiana (turnera Aphrodisiacal) for The Corrosion of aluminum in 1 M HCL Solution was investigated using weight loss measurements, galvanostatic, potentiodynamic anodic polarization techniques and elecrochemical impedance spectroscopy technique. The results drawn from these techniques indicate that the inhibition efficiency increase with the concentration of inhibitors increase but decrease with temperature. Inhibition was explained in term of the adsorption of the extract on the aluminum surface. The adsorption process is fitting Langmuir adsorption isotherm. It was found that extract protect aluminum surface from pitting attack in chloride containing solution by shifting the pitting corrosion potential to more noble direction . |
