Özet
The dependence of the pitting potential (E-p) of aluminum on chloride concentration, pH and the temperature of the solution was studied by the potentiodynamic method according to a statistical experimental design. The parameters of the statistical E-p model offered on the basis of Box-Wilson experimental design method were evaluated with the use of the experimental data. Comparison of the predicted values from the model with the observed values showed that the model is a good fit. From the model equation the most noble E-p value of -420 mV was obtained when Cl- ion concentration, temperature and pH of the solution were 57 ppm, 22 degrees C, and 8.3 respectively. Box-Wilson experimental design technique was proved to be applicable in modelling E-p of aluminum.
