Abstract

The effect of transition metals Cr, Co, and Ni on the structure, thermal conductivity, and strength characteristics of WC-Cu composites with a copper mesh structure has been studied. It is shown that WC70Cu30 composites doped with Co or Cr have high thermal conductivity, hardness, and wear resistance. The method of synthesizing composites differs from the existing ones by the absence of precursor stages of the formation of a rigid frame of refractory particles, as well as the activation of physico-chemical processes in a melt with refractory particles by precrystallization low-frequency vibration (80 Hz, amplitude 0.5 mm, 10 min).
