Conclusions A study was made of the effect of composition, structure, and properties of tungsten carbide pseudoalloys on processing parameters in electric-spark machining. WC-base pseudo-alloys exhibit adequate ductility under operating conditions: Their tough-to-brittle transition takes place at subzero temperatures. This markedly increases the erosion resistance of the pseudoalloys compared with pure tungsten carbide. The structure of a heterogeneous composite promotes selective evaporation of its low-melting-point constituent, which increases the rate of material removal in the electric-spark machining of refractory metals and VK20 hard metal. The introduction of an addition of low work function intensifies removal of material in electric-spark machining.
