METHOD OF PRODUCING NANODISPERSED HARD-ALLOY COMPOSITIONS BASED ON DOUBLE TUNGSTEN CARBIDE AND COBALT Russian patent published in 2009 - IPC C25C5/04 B82B3/00 C01B31/34 

FIELD: chemistry.

SUBSTANCE: invention relates to electrochemical synthesis of refractory tungsten compounds and can be used for producing nanodispersed hard-alloy compositions based on tungsten carbide and cobalt, with high melting points, hardness, strength, elasticity, chemical inertness. A melt, containing, mol %: lithium tungstate 30.0 to 40.0, cobalt tungstate 2.5 to 5.0, lithium carbonate 15.0 to 20.0, sodium tungstate - the rest, undergoes electrolysis in open cells in galvanostatic mode with cathode current density ranging from 2.5 to 7.5 A/cm².

EFFECT: obtaining power with particles size ranging from 50 to 500 nm, doubling rate of synthesis of desired product, simplification of the process.
