SOLUTION: The coated cutting tool comprises a cemented carbide body coated with α-Al 2 O 3 of (006) orientation. The cemented carbide body contains metal forming 4.5-6.5 wt.% of Co and 3-10 wt.% of cubic carbide. A value S is 0.77-0.92 and coercive force is 10-20 kA/m. Thickness of α-Al 2 O 3 layer is within a range of 7-12 μm, and the layer is composed of columnar crystal grains having a ratio of length/width within a range of 2-12 and formed on an MTCVD Ti(C, N) layer having thickness of 4-12 μm by evaporation. An Alumina layer is oriented (006). In the tool with black and shining appearance, the alumina layer becomes the uppermost layer and Ra is made to be less than 1 μm by wet blasting.

Abstract: PROBLEM TO BE SOLVED: To disclose a cutting tool insert coated with α-Al 2 O 3 combining cemented carbide accompanied with a binder phase enrichment surface area and a texture-processed α-Al 2 O 3 layer. SOLUTION: The α-Al 2 O 3 layer has a thickness in a range of 2 to 9 μm and is formed of columnar grains having a length/width ratio of 2 to 12. This is characterized by strong (104) growth texture and low strength of (012), (110) and (113) diffraction peaks. The texture-processed α-Al 2 O 3 is preferably coated on an MTCVDTi (C, N) layer having a thickness of 2 to 10 μm. When an alumina layer is the uppermost layer, a shiny black appearance can be given to a tool by wet-blasting the alumina layer to an Ra value of less than 1 μm. COPYRIGHT: (C)2009,JPO&INPIT
