Morphology and Properties of the Powder Prepared by the Electroerosive Dispersion of Wastes from the Tungstenless TN20 Hard Alloy in Water

Abstract—A powder consisting of mainly spherical particles with an average size of 15.3 μm is prepared by the electrodispersive dispersion of wastes from the tungstenless TN20 hard alloy in water. Elliptic particles and agglomerates are also observed in the powder. The phase composition is presented by titanium oxide Тi₂О₃ (3%), titanium carbide TiС (78%), and intermetallic compound ТiNi₃ (19%). For the chosen parameters of the process, the flow rate of the powder is low because of its high dispersive capacity.
