Abstract
(EN)
This coated tool comprises a base and a coating layer positioned upon the base. The coating layer has: a first layer positioned in the vicinity of the base and having a thickness of at least 1 µm; and a second layer in contact with the first layer, positioned further away from the base than the first layer, and including a plurality of Al2O3 particles. The difference (A2 – A1) between an erosion rate A2 in the second layer and an erosion rate A1 in the first layer is 0.60 to –0.30 µm/g, said erosion rates being obtained by causing a fluid A to collide with each layer, said fluid A comprising 3% by mass of spherical Al2O3 particles having an average particle diameter of 1.1–1.3 µm, dispersed in pure water. This cutting tool comprises: a holder extending from a first end towards a second end and having a pocket on the first end side; and the coated tool positioned in the pocket.

L'invention concerne un outil à revêtement comprenant une base et une couche de revêtement positionnée sur la base. La couche de revêtement comprend : une première couche positionnée au voisinage de la base et ayant une épaisseur d'au moins 1 µm, et une seconde couche en contact avec la première couche, positionnée plus loin de la base que la première couche, et comprenant une pluralité de particules d'Al 2O3. La différence (A2 – A1) entre un taux d'érosion A2 dans la seconde couche et un taux d'érosion A1 dans la première couche est de 0,60 à – 0,30 µm/g, lesdits taux d'érosion étant obtenus en amenant un fluide A à entrer en collision avec chaque couche, ledit fluide A comprenant 3 % en masse de particules sphériques d'Al 2O3 ayant un diamètre moyen de particules de 1,1 à 1,3 µm, dispersées dans de l'eau pure. Cet outil de coupe comprend : un support qui s'étend d'une première extrémité vers une seconde extrémité et qui a une poche sur le premier côté d'extrémité ; et l'outil revêtu est placé dans la poche.
