Název v původním jazyce

Study of corrosion resistance of zinc pigmented coatings containing polyaniline salt

Popis výsledku v původním jazyce

This work was devoted to the preparation of organic coatings containing a zinc pigment together with a polyaniline salt at different pigment concentrations and to the examination of their corrosion resistance. The coatings were pigmented with spherical or lamellar zinc and contained polyaniline phosphate, the pigment volume concentrations (PVC) were 1%, 5%, 10% and 15%. The same systems, only free from polyaniline phosphate, served as the reference materials. Corrosion resistance of the coatings was examined by several methods, primarily by an accelerated cyclic corrosion test in sodium chloride fog atmosphere, to which the coatings were exposed during 1440 hours. Electrochemical methods were also used to examine the coatings&apos; corrosion resistance. Specifically, the potentials of the coatings in 0.05 M sodium chloride solutions were measured against a tungsten electrode for 480 hours. The electrochemical method of linear polarisation in a 1 M sodium chloride solution was also used. The polarisation curves were processed to obtain the polarisation resistances and corrosion rates.
