Description

Abstract: To protect parts and structures operating in corrosive environments, zinc coatings obtained under SHS conditions are widely used. However, an objective assessment of the quality of zinc coatings is difficult. In this paper, a new method for controlling zinc coatings is proposed – an effective benchmark (ECP-Zn) that takes into account operational properties, microstructure, phase composition, thickness of zinc coating. ECP-Zn was determined for zinc coatings obtained under SHS conditions, which was compared with hot dip galvanizing, electroplating, and thermal diffusion zinc coatings. Zinc coatings including a G-phase with a continuous cubic lattice, a δ-phase (FeZn7) with a hexagonal lattice, zinc oxides, and also a ξ – phase (FeZn13) were compared.
