The additive articles made from the powders fabricated by electric discharge dispersion of the wastes of cobalt–chromium alloys are studied. These articles are shown to have a fine-grained structure without inclusions and discontinuities, and their porosity decreases with increasing fusion temperature. An increase in the fusion temperature 120°C in the temperature range under study is found to decrease the porosity of the articles by a factor of 4.5.
