Περίληψη:
This study investigates and evaluates the protection offered by the combination of two intrinsically conductive polymers, polypyrrole and polyaniline, when applied onto pretreated Al2024-T3 substrates by a cyclic voltametric technique. All coatings produced in this work show homogeneity and strong adhesion to the substrate. The effect of the electrolyte concentration and potential sweep rate is investigated, while the composition of the deposited coatings is analyzed by the potentiodynamic data of the potentiodynamic curves; cyclic voltamograms acquired on the formed coatings, in monomer-free solutions. Scanning electron microscopy (SEM) images and EDAX analysis employed to characterize the morphology and composition of the formed coatings. The electrochemical behaviour of the coatings evaluated through Potentiodynamic and Open Circuit Potential (OCP) measurements. Evaluation of the performance of the formed coatings suggests an improved electrochemical behaviour when compared to the pretreated uncoated substrate. © 2010 Elsevier B.V. All rights reserved.
