Certification of the Powder Materials Produced by Electrodispersion of a Tungsten-Free TN20 Hard Alloy in Alcohol
摘要
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.
