FIELD: process engineering.
SUBSTANCE: invention relates to grinding and may be used for production of abrasive tools, for example, grinding wheels. Abrasive article comprises abrasive body with abrasive grains in binder. Abrasive body comprises the region of passivation including spinel material that covers at least 60% of abrasive grains. Note here that said spinel material can be arranged at interface between abrasive grains and binder matrix.
EFFECT: decreased dissolution and destruction of abrasive grains in forming of abrasive article.
