Title (EN) COMPOSITE ARTICLE WITH COOLANT CHANNELS AND TOOL FABRICATION METHOD
(FR) ARTICLE COMPOSITE AVEC DES CANAUX DE RÉFRIGÉRATION ET PROCÉDÉ DE FABRICATION D'OUTILS
Abstract:
(EN) Embodiments of the present invention include composite articles comprising at least a first region and a second region and methods of making such articles. The first region may comprise a first composite material, wherein the first region comprises less than 5 wt. % cubic carbides by weight, and the second region may comprise a second composite material, wherein the second composite material differs from the first composite material in at least one characteristic. The composite article may additionally comprise at least one coolant channel. In certain embodiments, the first and second composite material may individually comprise hard particles in a binder, wherein the hard particles independently comprise at least one of a carbide, a nitride, aboride, a silicide, an oxide, and solid solutions thereof and the binder comprises at least one metal selected from cobalt, nickel, iron and alloys thereof. In specific embodiments, the first composite material and the second composite material may individually comprise metal carbides in a binder, such as a cemented carbide.
(FR) Les modes de réalisation de la présente invention comprennent des articles composites comprenant au moins une première région et une seconde région et des procédés de fabrication de tels articles. La première région peut comprendre un premier matériau composite, laquelle première région comprenant moins de 5 % en poids de carbures cubiques, et la seconde région peut comprendre un second matériau composite, lequel second matériau composite différant du premier matériau composite en ce qui concerne au moins une caractéristique. L'article composite peut en outre comprendre au moins un canal de réfrigération. Dans certains modes de réalisation, les premier et second matériaux composites peuvent individuellement être constitués de particules dures dans un liant, les particules dures comprenant indépendamment au moins un élément parmi un carbure, un nitrure, un borure, un siliciure, un oxyde, et des solutions solides de ceux-ci et le liant comprenant au moins un métal choisi parmi le cobalt, le nickel, le fer et des alliages de ceux-ci. Dans des modes de réalisation spécifiques, le premier matériau composite et le second matériau composite peuvent individuellement être constitués de carbures de métaux dans un liant, tels qu'un carbure cimenté.
