Abstract

L'invention porte sur un insert de carbure cémenté revêtu (outil de coupe) de fraisage humide ou à sec de la fonte, des aciers, et des aciers inoxydables, dans des applications requérant la ténacité et la résistance à l'usure. Un tel insert présente un corps de carbure cémenté comportant 10-15 % en poids de Co, 0.1-4 % en poids de carbures cubiques de Ti, Nb et Ta et le reliquat de WC, sa coercivité (Hc) étant de 10-19 kA/m, et la phase de liant alliée à du W correspondant à une valeur de S comprise entre 0,81 et 0,95. Le revêtement comprend une première couche intérieure de TiCxNyOz où 0,7 ≤ x+y+z ≤ 1, à grains équiaxés et d'une épaisseur totale de < 1 μm; une couche de TiCxNyOz où 0,7 ≤ x+y+z ≤ 1, à grains en colonnes et d'une épaisseur de 4 à 8 μm; et une couche de Al2O3 consistant en une phase alpha d'une épaisseur de 3,5 à 7 μm, fortement texturée dans la direction (1014). L'invention porte également sur une méthode d'élaboration d'inserts de carbure cémenté utilisant la technique MTCVD de dépôt de couches de grains en colonne.
