Patent ID: 10882116

Abstract:
A coated cutting tool comprising a substrate and a coating layer formed on the substrate, wherein: the coating layer is laminated in order from the substrate side toward a surface side of the coating layer; and the coating layer comprises an upper layer and a lower layer which satisfy the following conditions that: “at least one of {422} planes of TiCN particles located closest to the surface in the lower layer and at least one of {006} planes of α-type Al2O3 particles located closest to the substrate in the upper layer and immediately above the TiCN particles are substantially parallel to each other, and at least one of {111} planes of the TiCN particles and at least one of {110} planes of the α-type Al2O3 particles are substantially parallel to each other”; and “at least one of {111} planes of TiCN particles located closest to the surface in the lower layer and at least one of {006} planes of α-type Al2O3 particles located closest to the substrate in the upper layer and immediately above the TiCN particles are substantially parallel to each other, and at least one of {422} planes of the TiCN particles and at least one of {110} planes of the α-type Al2O3 particles are substantially parallel to each other.”
