Application of self-propagating high-temperature synthesis and mechanoactivating treatment for producing multi-component composite alloying materials

摘要

The work is devoted to the important problem of producing new class powdered materials by mechanically activated self-propagating high-temperature synthesis (SHS). Mechanical activation and SHS technologies are discussed; the method of producing powder mixture for the powder electrode core (wire) is discussed. It was established that introducing hard particles (carbides) into the surface layer by means of arc surfacing with SHS-powdered electrodes increases the wear resistance of the welded layer.
