X-Ray Studies of the Powders Produced by Electrodispersion of the Waste of a Tungsten-Free TN20 Hard Alloy
摘要
Abstract
X-ray studies are performed to study the powders fabricated by electrodispersion of the waste of a TN20 tungsten-free hard alloy (TFHA) in various working fluids. The electrodispersion of the TN20 TFHA waste in alcohol is shown to ensure the supply of active carbon to a reaction zone at temperatures initiating the formation of carbide phases and the presence of free carbon on the surface, and the electrodispersion of the TN20 TFHA waste in water promotes the formation of oxide phases and the presence of oxygen on the surface.
