dc.description.abstract | The present work has the purpose of obtaining composite coatings in zinc matrix
by using phenol - formaldehyde resin type NOVOLAC (RESITAL 6358/1) in the
electrodeposition process of zinc. The PF resin/Zn composite coatings were
electrodeposited from a suspension of PF resin particles (diameter < 56 μm) in
aqueous zinc sulphate electrolyte. Suspension was prepared by adding 10g/L and
25g/L PF resin particles into solution. The pure zinc coating has a rather regular
surface, whereas the composite coatings surface has fine surface structure. For
layers obtained at 3A/dm2 the polarization resistance is higher for composite
coatings with 10 g/L PF resin (Rp = 238.75 Ω cm2) than pure zinc (Rp = 34.54 Ω
cm2). For layers obtained at 5A/dm2 the polarization resistance is higher for
composite coatings with 25 g/L PF resin (Rp = 430.19 Ω cm2) than pure zinc (Rp =
127.34Ω cm2). As test solution 0.5M sodium chloride was used, it was observed that
by adding PF resin particles in zinc electrolyte for electrodeposition it was obtained
a very good distribution of resin particles on zinc surface and PF resin/Zn
composite coatings obtained are most resistant at corrosive attack than pure zinc
obtained from electrodeposition under the same conditions. | ro_RO |
