ABSTRACT: Ti coated superhard abrasive (diamond and CBN) micro-powder can be produced industrially by vacuum

Slow vapor deposition technology. The finest Ti coated superhard abrasive micro-powder can be W5, featuring strong chemical bond between the coating and abrasive grain, homogeneous coating and no claster. Such coated micro-powedr have wide application field in making precision polishing tools and polycrystalline superhard composites.
