FIELD: metallurgy.SUBSTANCE: method involves filling of powder to a die, application of static pressure to it and passing of a current pulse through it; during application of pressure and passage of the current pulse, vibration of the die with frequency of 10-10Hz and amplitude of 10-5·10m is performed. At vibration of a ceramic die, interaction of its side surface with specimen material is reduced.EFFECT: increasing durability of a ceramic die; improving removal of a specimen; as a result, items with smooth and even side surface are obtained.1 ex, 1 dwg |
