Steel Galvanostatic deposition Tafel polarisation in 3.5% NaCl The corrosion rate of steel increases when the concentration of aniline in the electrolytic solution increases from 0.1 to 0.4 M. [26]... [Pg.544]

Steel Cyclic voltammetry Tafel polarisation in 0.1 MHCl EIS in 0.5 M NaCl, 0.1 MHCl Potentio dynamic polarisation in 0.5 M H SO All corrosion tests show the worst performance of PANl single coating with respect to the single PPy coating, PANl/PPy and PPy/PANl bi-layer coatings. [29]... [Pg.545]

PPy MMT Steel Dip coating Tafel polarisation in 5% NaCl increasing the MMT content in PPy from 0 to 10 wt.%, the corrosion current deceases and the corrosion potential shifts to nobler potential values. [57]... [Pg.560]

PANl Na-MMT Iron Casting Tafel polarisation in IM ff SO and 3.5% NaCl, Monitoring OCP in IM HCl The anticorrosion behaviour of PANi-i-Na-MMT is better than PAN and PANi-tO-MMT in NaCl, but worse than PAN and PANi-tO-MMT in H SO [56]... [Pg.560]

PANl Zn iron Casting Tafel polarisation and Monitoring OCP in O.IM HCl The corrosion rate values of PANi+Zn coatings with a different Zn content are lower than of pure PANl, but their kinetic anticorrosive properties get worse with increasing the zinc content. [53]... [Pg.562]

PANI TiO Steel Dip coating Tafel polarisation and Monitoring OOP in 3.5% NaCl The corrosion protection property of PANl-i-TiO coatings depends on TiO content. When the TiO content increases, the OCP shifts to potentials but the corrosion current increases. [48]... [Pg.563]
