Abstract

The increasing of working resource silicon nitride based materials for fabrication of aerial-abrasive nozzles was considered. The production scheme for fabrication silicon nitride aerial-abrasive nozzles by high-temperature direct extrusion method was presented. The possibility of increasing working resource silicon nitride aerial-abrasive nozzle due to structural strengthening at high-temperature deformation with achievement 20-30 % economy relatively with import analogues was shown.
