FIELD: process engineering.
SUBSTANCE: invention relates to grinding and may be used for production of abrasive tools, for example, grinding wheels. Abrasive article comprises substrate, mid layer arranged above the latter, abrasive particles with ply of coating located over abrasive particles bonded with mid layer to make the area of metallic bond between said ply of coating and mid ply. Bonding layer is located over abrasive particles and mid ply. Said area of metallic bond comprises the area of diffusion bond with mutual diffusion zone for at least one chemical particles of coating ply and other chemical particles of mid ply.
EFFECT: longer life.
