Title (EN) ABRASIVE AND WEAR RESISTANT MATERIAL
(FR) MATERIAU RESISTANT A L'USURE ET A L'ABRASION
Abstract: front page image
(EN)An abrasive and wear resistant material comprises a mass of carbide particles, a mass of cubic boron nitride particles, and a bonding metal or alloy, bonded into a coherent, sintered form. The cubic boron nitride particle content of the material is from 10% to 18% inclusive by weight, the particle size of the cubic boron nitride is less than 20 micron or less, and the material is substantially free of hexagonal boron nitride. The abrasive material is of particular use in tool components or inserts for application in the abrading of wood and other lignocellulosic materials.
(FR)L'invention concerne un matériau résistant à l'usure et à l'abrasion comprenant une masse de particules de carbure, une masse de particules de nitrure de bore cubique, et un métal ou un alliage de liaison, liés en une forme cohérente frittée. Le contenu en particules de nitrure de bore cubique du matériau est compris entre 10 et 18 % en poids, la taille particulaire du nitrure de bore cubique est inférieure à 20 microns, et le matériau est pratiquement exempt de nitrure de bore hexagonal. Le matériau abrasif est particulièrement utile pour des éléments ou pour des pièces rapportées servant à l'abrasion du bois et à l'abrasion d'autres matières ligneuses.
