Abstract
(EN)
This coated tool comprises a base and a coating layer positioned upon the base. The coating layer comprises: a first layer having a thickness of at least 1 µm and positioned near the base; and a second layer positioned further away from the base than the first layer. The erosion rate A2 of the second layer, obtained by causing a fluid A to collide with the second layer and measuring same, is no more than 0.4 µm/g, said fluid comprising spherical Al2O3 particles having an average particle diameter of 1.1–1.3 µm, dispersed in pure water. The erosion rate A1 in the first layer, obtained by causing the fluid A to collide with the first layer and measuring same, is no more than 1.8 µm/g. 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 revêtu comprenant une base et une couche de revêtement positionnée sur la base. La couche de revêtement comprend : une première couche ayant une épaisseur d'au moins 1 µm et positionnée à proximité de la base; et une seconde couche positionnée plus loin de la base que la première couche. Le taux d'érosion A2 de la seconde couche, obtenu en amenant un fluide A à entrer en collision avec la seconde couche et en mesurant celle-ci, n'est pas supérieur à 0,4 µm/g, ledit fluide comprenant des particules sphériques d'Al 2O3 ayant un diamètre moyen de particule de 1,1 à 1,3 µm, dispersées dans de l'eau pure. Le taux d'érosion A1 dans la première couche, obtenu en amenant le fluide A à entrer en collision avec la première couche et en mesurant celle-ci, n'est pas supérieur à 1,8 µm/g Cet outil de coupe comprend : un support qui s'étend d'une première extrémité à une seconde extrémité et qui a une poche sur le premier côté d'extrémité ; et l'outil revêtu disposé dans la poche.
