FIELD: chemical heat treatment of blanks and tools; mechanical engineering.
SUBSTANCE: proposed method includes placing solid ground agent into furnace, heating the furnace, introducing fluidizing gas, placing articles to be treated in furnace at fluidized layer made from complex component consisting of catalyst and neutral material; volume ratio of catalyst and neutral material ranges from 1:3 to 1:7.Use may be made of synthetic corundum at diameter of particles of 0.4-1.0 mm.
EFFECT: reduced consumption of expensive catalyst; low cost of process.
