Effect of Temperature on the Porosity of the Additive Products Made of the Dispersed Wastes of Cobalt–Chromium Alloys

Abstract

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.
