Title
(EN) ABRASIVE ARTICLE HAVING A DIAMOND-LIKE COATING LAYER AND METHOD
(FR) ARTICLE ABRASIF A REVETEMENT DE SIMILI DIAMANT ET PROCEDE ASSOCIE
Abstract
(EN)
An abrasive article having a sheet-like substrate having at least one major surface; an abrasive coating adhered to the at least one major surface of the substrate, wherein the abrasive coating comprises a plurality of abrasive particles and an organic binder medium; and, a hard carbon coating layer comprising a diamond-like carbon film. The hard carbon coating layer in the coated abrasive article can be provided as a top coat or, alternatively, as located between the abrasive coating and a covering layer based on an organic binder layer. The invention also pertains to a method of making such an abrasive article.
(FR)
Article abrasif à revêtement de simili diamant à substrat en feuille présentant au moins une surface principale à laquelle adhère un revêtement abrasif fait d'une multitude de particules abrasives et d'un liant organique, ainsi qu'une couche de carbone dur constituée par une pellicule de carbone simili diamant. La couche de carbone dur de l'article peut être disposée en surface ou bien entre la couche abrasive et une couche de couverture de liant organique. L'invention porte également sur le procédé de fabrication d'un tel article.
