FIELD: process engineering.
SUBSTANCE: invention can be used for production of abrasive materials. In compliance with this invention, abrasive particles represent shaped abrasive particles with inclined sidewall. Every shaped abrasive particle contains aluminium alpha-oxide and gas first and second faces separated by thickness t. Said shaped abrasive particles feature forming slope angle α between second face and inclined sidewall making 95-130 degrees or inclined sidewall with radius R between first and second faces. Radius R makes 0.5-2 if thickness t. Abrasive material with coating comprises bottom adhesive layer on the substrate first smooth surface, shaped abrasive particles making the abrasive layer and top adhesive layer. Most shaped abrasive particles are secured to bottom adhesive layer by inclined sidewall and feature orientation angle β equal to 50-85 degrees. Abrasive layer consists of shaped abrasive particles by at least 5% by weight.
EFFECT: higher efficiency of cutting.
