TEMPERING METHOD OF HARD ALLOY ON BASIS OF TUNGSTEN CARBIDE

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention relates to powder metallurgy, particularly to tempering method of hard alloys on the basis of tungsten carbide for boring tool. Alloy is heated up to the temperature higher 1100C and cooled in 6-11 % aqueous solution of Breox Thermo A on the basis of ethylene glycol and polypropylene glycol copolymer. ^ EFFECT: method provides increasing of alloy hardening and service durability of the tool. ^ 1 ex
