Certification of the Powder Materials Produced by Electrodispersion of a Tungsten-Free TN20 Hard Alloy in Alcohol
Based on experimental studies aimed at certifying the powder materials produced by electrodispersion of a TN20 tungsten-free hard alloy in alcohol, we have demonstrated a high efficiency of using electroerosion dispersion, which ensures the production of an alloy powder with a uniform distribution of alloying elements that is suitable for the production of cutting tools at low energy consumption. The carbide powder particles produced by electroerosion dispersion of the TN20 hard alloy waste in alcohol are shown to have spherical and elliptical shapes or exist in the form of agglomerates. The volume average particle diameter is 15.28 μm, carbon is detected on the particle surface, and all other elements (Ti, Ni, Mo) are distributed relatively uniformly. The presence of carbon in a working fluid leads to the formation of TiC, Mo2C, and TiNi2.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
