Abstract
Corrosion properties of diffusional zinc coatings with various surface compositions, obtained by nanogalvanizing technology, are studied in model oilfield and aggressive chloride-containing media. A complex of physical and chemical methods for studying corrosion behavior, including polarization measurements, X-ray diffraction analysis and SEM, was used in the work. Corrosion resistance of diffusional zinc coatings obtained by nanogalvanizing is determined by the composition, texture and thickness of the coating.
