Abstract

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°C, and 8.3 respectively. Box‐Wilson experimental design technique was proved to be applicable in modelling E~p~ of aluminum.
