FIELD: ceramic welding. SUBSTANCE: particles to be sprayed are fed to hopper 1 and then mixing chamber 3 and inlet zone 6 using slag transporter 2. Nitrogen is fed to chamber 3 through inlet 4. Nitrogen flows down together with the particles through directing cone 11. Oxygen is injected in input zone 6 through nozzle 5 under pressure and exhaust the particles and nitrogen from chamber 3. The gas flow, formed in so manner, is directed to the jet and a surface to be repaired. EFFECT: simplified method. 13 cl, 2 dwg
