Abstract

Methods and processes of surface hardening of parts from iron-carbon alloys are analyzed. It is shown that each of the known methods has advantages and disadvantages. A complex process for hardening of parts from iron-carbon alloys is suggested for obtaining the specified combination of properties. In the first stage of the complex treatment the part is subjected to vacuum-plasma sputtering and then to a thermochemical saturation in superheated vapor of aqueous solutions of salts. The coating is formed layer-after-layer, which raises its tribotechnical properties and prolongs the service life of the coated material by a factor of 3 – 4.
