COMPOUND FOR PLASMA-JET-POWDER HARD-FACING OF ABRASION-RESISTANT FINISH ON MACHINE ELEMENTS CONTAINING TUNGSTEN CARBIDE AND TITANIUM CARBIDE POWDER Russian patent published in 2009 - IPC B23K35/32 C23C4/04 

FIELD: mechanical engineering.

SUBSTANCE: invention may be used for creation of abrasion-resistant finish on machine elements subjected to intensive wearing in conditions of mass, serial and single-piece production. The compound uses tungsten carbide and titanium carbide powder created in the process of electrical discharge dispersion of wastes of T15K6 grade hard alloy in kerosene. Average particle size is 35-40 mcm. Powders produced of wastes of T15K6 grade hard alloy are not contaminated with products of chipper mechanical parts wear, significantly cheaper than commercially available ones, and have competitive mechanical-and-physical properties. In their structure these powders contain highly-rigid phases - α-WC, W₂C and TiC carbides - the harness of which is higher than abrasive hardness.

EFFECT: simultaneously, disposal problem for wastes of T15K6 grade hard alloy is solved.
