  • To know the growth behavior of Conductive polyaniline file, the anodic oxidation of anilien on a platiunm in aqueous sulfuric acid solution has been studied. Cyclic votammetry and currenttime transisents method used to investigate the anodic oxidation of aniline to polyaniline films on a platinum. The oxidation of aniline is shown to occur in several steps dependent on the potential. it the phase growth resembles the deposition of a metal film.

  • This study was made on the crevice corrosion behavior of chromium plating in fresh water. Under the various crevice, the electrochemical polarization test of chromium plating was carried out. Results are discussed In terms of corrosion potential, polarization resistance, corrosion current density and cathodic control of chromium plating.
