FIELD: technological processes.
SUBSTANCE: invention relates to spark plasma sintering of composite powders under pressure. Device comprises matrix and installed inside it with formation of sintering zone and possibility of forming in it of pressing force working elements, made with possibility of connection to power supply with passage of electric current through composite powder. Matrix and said working elements are made from sintered tungsten carbide powder.
EFFECT: eliminating contamination of manufactured articles with carbon admixture, as well as improving mechanical strength of the device.
