Obtaining microdispersed iron-nickel powder in the process of electrochemical processing of VNZh type heavy tungsten alloys

Abstract

The process of electrochemical processing of the VNZh type heavy tungsten alloy (wt. %: 80 W, 16 Ni, 4 Fe) under the action of direct and alternating current of industrial frequency in an ammonia-alkaline solution has been investigated. It was found, that the process is accompanied by the transition of tungsten from the alloy to the solution and the formation of a microdispersed powder, based on iron and nickel.
