FIELD: metallurgy.
SUBSTANCE: hardening superhard nanosized particles and plasticiser substances are introduced successively in plasticiser solution. Excess amount of solvent is evaporated from obtained suspension at temperature some 30-50°C lower than that plasticiser decomposition so that its amount relative plasticiser substances does not exceed 10%.Thereafter, plasticiser is introduced in hard alloy powder mix. Mixing of superhard nanosized particles with solvent and evaporation of excess amount of solvent from suspension are conducted in cavitation field of ultrasound.
EFFECT: homogeneous charge and uniform wear of tool female die.
