<p class="AMSmaintext"><span lang="EN-US">The new method for hardening ready-made steels, hard alloys and diamond tools is developed: low-temperature process for producing thin-film solid lubricant coatings by hydro chemical treatment in specially prepared aqueous media of nanosized hard refractory compounds and subsequent tempering. The main advantages of the method over known processes are presented. The principles for dispersion of refractory materials are formulated. The structure and properties of the obtained coatings are examined. <br /></span></p>

The new surface hardening methods for hard alloys are developed: (1) high-temperature process for producing multicomponent carbide coatings by thermochemical heat treatment of hard alloys at 1050 °C and (2) low-temperature process for producing thin-film coatings by chemical treatment of hard alloys in specially prepared aqueous suspensions of nanosized hard refractory compounds and subsequent tempering (minimal temperature is 130°C). The structure and properties of the obtained coatings are examined. The coatings permit improving substantially the service life of cutting tools.
