Title (EN) COATED ABRASIVE ALUMINA PARTICLES, MANUFACTURE AND USE
(FR) PARTICULES D'ALUMINE ABRASIVES ET ENROBEES, FABRICATION ET UTILISATION
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.
(FR) On décrit des particules abrasives comportant un noyau de minéral à base d'alumine revêtu par le dépôt à arc cathodique d'un matériau réfractaire de borure, de carbure ou de nitrure métallique. Le noyau peut être constitué d'électro-corindon ou d'une céramique à base d'alumine. On décrit également des produits abrasifs améliorés dont au moins une partie des particules abrasives traditionnelles sont remplacées par lesdites particules abrasives précitées.
