METHOD OF MAKING ABRASIVE TOOL FROM SUPERHARD MATERIALS Russian patent published in 2012 - IPC B24D18/00 B24D3/06 B23K35/24 

FIELD: process engineering.

SUBSTANCE: invention relates to abrasion and may be used in production of abrasive tool from diamond and boron nitride on metal binder. Particles of superhard materials and composite solder are applied on substrate surface. Said solder includes fusible matrix, refractory filler, and binder. Fusible matrix represents powders of Ag, Sn, Al or allows containing said metals. Substrate with said applied particles and solder are annealed in protective atmosphere or in vacuum at temperature of mutual diffusion of fusible matrix and refractory filler components to produce structural components with fusion temperature exceeding that of annealing. Fusible matrix components doe not, in fact, evaporate in annealing.

EFFECT: high strength, durability and wear resistance.
