The thermal spraying of metallic coating (zinc, Zn-Al15, etc.) from wire is suitable technique for surface treatment corrosion protection of large structures. This study was carried out to investigate and evaluate the properties of zinc coatings affected by spraying techniques - heated by electrical arc or flame. The panels with different coatings were exposed at atmospheric and accelerated tests. The article gives the overall evaluation of properties of these coatings.Keywords: Thermally sprayed coating, structure, adhesion, corrosion
