The results show that lower opencircuitpotential and current efficiency, higher whiteness, better coating binding force were found when the substrate was nickel;
Cathodic reaction rate at opencircuitPotential for iron in sulfuric acid containing dichromate ion was controlled by both electron transfer process and diffusion process.
Inhibitive effects of polyaniline (PANI) for the corrosion of mild steel were studied using visual observation, opencircuitpotential (OCP) and linear polarisation resistance (LPR).
