Abstract: For car parts working in conditions of wear process, sign-variable loadings, heats, speeds and pressure, and also aggressive corrosion environments, properties of a superficial layer have great value. In many cases the most widespread decision of the given problem appears set of a strong constructional material proof to temperature, deterioration, corrosion on working surfaces. The zinc coverings possess that specified properties. The received zinc layer consists of two zones: zones of zinc layers (chemical compounds of zinc and iron) and a transitive zone (a firm solution of zinc in iron). Zinc-plating to steel in conditions SHS promotes reception on its surface high quality diffusion coverings. Hardening of superficial layers carbonaceous steels method SHS allows to receive one thing – and the biphasic zinc coverings alloyed by chrome and aluminum, with corrosion stability 40 % above, than after zinc-plating a standard method.
