Title: (EN) Coated abrasive alumina particles, manufacture and use
Abstract:
(EN) Abrasive particles comprising a core of alumina-based mineral coated by cathodic arc deposition with a metal boride, carbide, or nitride refractory material are provided. The core can be fused alumina or an alumina-based ceramic. Improved abrasive products having at least a portion of their conventional abrasive particles replaced with the coated abrasive particles are also provided.
