Title (EN) TAP DRILL WITH ENHANCED PERFORMANCE
(FR) TARAUD À PERFORMANCES AMÉLIORÉES
Abstract:
(EN) The present invention relates to a tap drill comprising a substrate and a coating, wherein the coating is deposited on at least a portion of the substrate comprising the head of the drill, the coating comprising a first layer deposited directly on the substrate and a second layer deposited atop the first layer, wherein the first layer is a wear resistant layer of (Al,Cr)N deposited by Hi PIMS and the second layer is a friction reduction layer, wherein the second layer is a metal carbide layer or a metal-carbide comprising layer deposited by using a physical vapor deposition (PVD) process of the type magnetron sputtering, preferably of the type HiPIMS.
(FR) La présente invention concerne un taraud comprenant un substrat et un revêtement, le revêtement étant déposé sur au moins une partie du substrat comprenant la tête du foret, le revêtement comprenant une première couche déposée directement sur le substrat et une seconde couche déposée au-dessus de la première couche, la première couche étant une couche résistante à l'usure de (Al,Cr)N déposée par HiPIMS et la seconde couche étant une couche de réduction de frottement, la seconde couche étant une couche de carbure métallique ou une couche comprenant du carbure métallique déposée en utilisant un procédé de dépôt physique en phase vapeur (PVD), du type à pulvérisation cathodique magnétron, de préférence du type HiPIMS.
