(FR) OUTIL DE COUPE ENROBÉ ET SON PROCESSUS DE FABRICATION
Abstract:
(EN) The Invention relates to a coated cutting tool and to a process for manufacturing a coated cutting tool consisting of a substrate and a single-layer or multi-layer hard material coating, the substrate being selected from cemented carbide, cermet, ceramics, cubic boron nitride (cBN), polycrystalline diamond (PCD) or high-speed steel (HSS), and the hard coating comprising at least one layer of AlaCrbMecOdNe, wherein a, b, c, d, and e are atomic ratios, and wherein a + b + c + d + e = 1, a, b, d and e each are > 0, c = 0 or c > 0, a ≥ b, c / (a + b + c) ≤ 0.1, preferably ≤ 0.05, 0.1 ≤ d / (d + e) ≤ 0.5, wherein Me is at least one element selected from the group consisting of Ti, Zr, Ta, Nb, Hf, Si, and V, and wherein the AlaCrbMecOdNe layer is deposited by an arc vapor deposition process (Arc-PVD) using targets containing Al and Cr with an Al:Cr atomic ratio in the range of 95:5 to 50:50, and wherein - the reaction gas mixture contains O2 gas and N2 gas, wherein optionally a portion or all of the O2 gas and a portion of the N2 gas is replaced by a nitrogen and oxygen containing gas, selected from nitrous oxide, N2O, nitric oxide, NO, nitrogen dioxide, NO2, and dinitrogen tetroxide, N2O4, - the reaction gas mixture optionally contains one or more inert gases, - the total gas pressure is within the range from 7 Pa to 20 Pa, - the O2 partial pressure is from 0.001 Pa to 0.1 Pa, - 0.002 ≤ (flow rate (O2) / flow rate (N2) ≤ 0.02, - (flow rate (O2) + flow rate (N2)) / flow rate (inert gas) ≥ 4.
(FR) L'invention concerne un outil de coupe enrobé et un processus de fabrication d'un outil de coupe enrobé comprenant un substrat et un revêtement en matériau dur monocouche ou multicouche, le substrat étant sélectionné parmi le carbure cémenté, le cermet, les céramiques, le nitrure de bore cubique (cBN), le diamant polycrystallin (PCD) ou l'acier à coupe rapide (HSS), et le revêtement dur comprenant au moins une couche de AlaCrbMecOdNe, où a, b, c, d, et e sont des rapports atomiques, et où a + b + c + d + e = 1, a, b, d et e sont chacun > 0, c = 0 ou c > 0, a ≥ b, c/(a + b + c) ≤ 0,1, de préférence ≤ 0,05, 0,1 ≤ d/(d + e) ≤ 0,5, où Me est au moins un élément sélectionné dans le groupe constitué par Ti, Zr, Ta, Nb, Hf, Si, et V, et où la couche AlaCrbMecOdNe est déposée par un processus de dépôt en phase vapeur par arc (Arc-PVD) à l'aide de cibles contenant Al et Cr avec un rapport atomique Al:Cr dans la plage de 95:5 à 50:50, et où - le mélange de gaz de réaction contient de l'O2 gazeux et du N2 gazeux, où éventuellement une partie ou tout l'O2 gazeux et une partie du N2 gazeux sont remplacés par du gaz contenant de l'azote et de l'oxygène, choisi parmi l'oxyde nitreux, N2O, l'oxyde nitrique, NO, le dioxyde d'azote, NO2, et le tétroxyde de diazote, N2O4, - le mélange de gaz de réaction contient éventuellement un ou plusieurs gaz inertes, - la pression gazeuse totale est dans la plage de 7 Pa à 20 Pa, - la pression partielle d'O2 est de 0,001 Pa à 0,1 Pa, - 0,002 ≤ (débit (O2)/débit (N2) ≤ 0,02, - (débit (O2) + débit (N2))/débit (gaz inerte) ≥ 4.
