摘要
Plackett–Burman experimental design was carried out in order to optimize the experimental conditions of polyaniline (PANI) electrodeposition for Cu10Sn bronze alloy corrosion protection in neutral aerated aqueous 0.5 M chloride medium. Seven factors including scan rate, aniline concentration, hydroxyl ions concentration, cycle number, nature of solvent, starting potential, and final potential for the cyclic voltammetry study were considered. The experimental responses were Ecorr, βa, βc, B, Jcorr, Rp, the percentage of protection efficiency and the coatings porosities. A linear mathematical model was applied to estimate the coefficients related to the different experimental responses. The significance of the different factors was evaluated through Pareto analysis. The optimum conditions for PANI electrodeposition were estimated and discussed. PANI coatings were concluded to offer protection efficiency higher than 90% for Cu10Sn bronze alloy.
