Title:
METHOD FOR OBTAINING ELECTRODE MATERIAL FOR ELECTROSPARK ALLOYING
Document Type and Number:
WIPO Patent Application WO/1991/009979
Kind Code:
A1
Abstract:
The method provides for initiating a burning reaction in an exothermic mixture with the following composition in per cent by weight: a transition metal 32-86, carbon and/or boron 4-28, modifying addition 1-10, compacting the solid products of the burning reaction by their extrusion at a deformation rate of 0.9-0.995 within a temperature range of 1800-1000 �C with subsequent conditioning of the extruded material at a temperature of 500-50 �C in a vacuum or inert medium for 0.1-15 minutes.
