摘要：
We report the formation of polypyrrole (PPy) coatings on Mg alloy AZ91D from aqueous solutions of a dicarboxylic organic acid salt by cyclic voltammetry (CV) method. The polymeric films of PPy are directly coated onto AZ91D substrates without any pretreatment or intermediate steps. The electro-chemically formed PPy films were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), X-Ray photoelectron spectroscopy (XPS) and time of flight secondary ion mass spectrometry (ToF-SIMS). Electrochemical impedance spectroscopy (EIS) measurements demonstrate a good corrosion protection. (C) 2010 Elsevier B.V. All rights reserved.
