FIELD: electron-beam surfacing of flat and cylindrical surfaces, possibly manufacture of new parts and restoration of worn surfaces of parts operating at condition of intensified abrasive wear in combination with impact loads.
SUBSTANCE: in order to enlarge manufacturing possibilities of method, on surface of welded-on article melting zone by means of electron beam is created. Powder composition material for surfacing is fed to melting zone. Surfaced article is moved and powder material for surfacing is fed normally relative to motion direction of article. As coating is applied unfocused electron beam is used for acting upon surface of said coating without supply of material for surfacing. It provides separation of dispersed particles of strengthener from solid solution and formation of multimodal structure of surfacing along its whole thickness.
EFFECT: enlarged manufacturing possibilities of method.
