METHOD OF PRODUCTION OF NICKEL AND RHENIUM POWDERS WITH DIFFERENT CONTENT OF COMPONENTS DURING PROCESSING OF RHENIUM CONTAINING HEAT-RESISTING NICKEL ALLOYS

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to the recovery of secondary metal scraps, in particular, to processing of metal scraps of nickel-based rhenium containing heat-resisting alloys. Under method the electro-chemical dissolution of the heat-resisting alloy is performed upon anode polarization by pulse current at constant parameters (current) in nitric electrolyte with further nickel and rhenium extraction at monitored cathode potential. The inert electrode is used as cathode. The soluble alloy is used as anode. Dissolution of the nickel-based rhenium containing heat-resisting alloy is performed at fixed current density, and further extraction of nickel and rhenium is performed at monitored cathode potential.EFFECT: processing of the nickel-based rhenium containing heat-resisting alloys with production of nickel and rhenium powders with different composition of components.5 ex
