Abstract: front page image
(EN)The invention provides abrasive articles (30) comprising: a backing (32) having a first major surface and a second major surface; and an abrasive coating (37) consisting essentially of: a hardened binder coating having a first surface adhered to the flexible backing (32) and a second structured surface comprising a plurality of precisely-shaped protrusions; and a diamond-like carbon coating superposed and adhered to at least a portion of the structured surface of the hardened binder coating. Also reported is a method of mechanically treating a rigid disk or a rigid disk substrate (12) using the abrasive articles (30) of the present invention.
(FR)La présente invention concerne des articles abrasifs comprenant: (a) un support présentant une surface principale et une surface secondaire, et (b) un revêtement abrasif composé essentiellement: (i) d'un revêtement de liaison durci présentant une première surface collée au support souple et une seconde surface structurée présentant une pluralité de protubérances taillées avec précision; et (ii) d'un revêtement de carbone de type diamant superposé et collé à au moins une partie de la surface structurée du revêtement de liaison durci. La présente invention concerne également un procédé permettant de traiter mécaniquement un disque dur ou un substrat de disque dur à l'aide des articles abrasifs décrits dans cette invention.
