Influence of the properties of working liquid on the size characteristics of powders obtained under the conditions of electroerosion metallurgy of the wastes of TN20 tungsten-free hard alloy
On the basis of the results of experimental studies aimed at the investigation of the influence of dielectric permittivity of a working liquid on the size characteristics of powders obtained under the conditions of electroerosion metallurgy of the wastes of TN20 tungsten-free hard alloy, it was discovered that the higher dielectric permittivity of water leads to a greater loss of the pulse energy required for its breakdown than in the case of breakdown in ethanol and the formation of powder characterized by a smaller average size of particles, namely, 14.3 and 28.4 μm, respectively. The results of conducted experimental studies enable us to solve the problem of recycling of the wastes of tungsten-free hard alloys and their subsequent utilization, thus reducing the cost of production of cutting tools.
