Abstract
The method relates to inorganic chemistry. Pursuant to the method, a powder mixture comprising a transition metal, a nonmetal, an inert filler and an activator is prepared; a workpiece to be coated is embedded in the powder mixture and this is placed, integrally with the workpiece, into an oxygen-free medium for a subsequent heat treatment which is accomplished by a locally-initiated combustion of the powder mixture.
