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 h

The nitriding of a grade 45 carbon steel with a zinc-filled coating (ZFC), which was preliminary formed by cold galvanizing, is considered. The microstructure and the chemical and phase compositions of the modified layer are studied experimentally. I

Chemicothermal treatment of steel is considered: specifically, diffusional zinc coating in a nitrogen-bearing medium; and nitriding of a preformed zinc-filled coating. The structure of the modified layers is investigated. Their microhardness and wear
