Powder Metallurgy and Metal Ceramics Aims and scope

Abstract

The velocity and temperature of particles resulting from the electrospark erosion of the anode are assessed. A mathematical model is developed to describe the mechanical interaction of particles with the substrate. The deformation and heat exchange between the substrate and copper and tungsten carbide particles with different initial temperature and velocity are calculated. Data on the final deformation, crystallization and cooling time of the particles, and the probability of their adhesion with the substrate are obtained.
