Improvement of electrochemical action of zinc-rich paints by addition of nanoparticulate zinc

Abstract

The influence of nanosized particles on electrochemical action of standard zinc-rich paints by means of SEM as well as potential and impedance measurements has been investigated. The motivation for doing this was to obtain additional electrical connection between the spherical microparticles themselves and zinc particles and steel substrate. Overall zinc content was at the level of 92% by weight. Samples with different concentration of nanoparticulate zinc (0%, 5%, 10% and 40%) were tested. Addition of 5–10% nanoparticulates extended the galvanic action of the coating in comparison to the standard zinc-rich coating.
