A method is proposed to improve the service properties of the zinc coatings on steels formed by cold galvanizing in order to increase their reliability and durability. As a result of annealing a zinc coating in an ammonia medium, the formation of a hardened modified layer due to diffusion processes in both a steel substrate and a zinc coating is experimentally established. The structure of the hardened layer provides an increase in the wear resistance of the nitrided zinc coating and an increase in the adhesion of the coating to the substrate. The corrosion resistance of the nitrided zinc coatings in various media, namely, a saline solution, a weakly acidic medium, seawater, and salt fog, is shown to increase due to a combination of cathodic and barrier protection mechanisms.
