Example Embodiment
[0047] Example 1:
[0048] Kind of like figure 1 The cutting tool with improved coating structure of the present invention shown includes a substrate A1 and a coating 2 at least partially covered on the substrate A1. The coating 2 includes at least an inner layer B21, a transition layer C22, and an outer layer from the inside to the outside. D23.
[0049] among them:
[0050] The inner layer B21 is mainly composed of MT-TiCN material with a thickness of 6μm;
[0051] The outer layer D23 is mainly composed of α-Al 2 O 3 Material composition, thickness d=4μm, outer layer D23 is an ultra-fine crystal oxide coating, outer layer D is α-Al 2 O 3 The average grain size S is 0.46μm;
[0052] The transition layer C22 includes transition layer C1 221 and transition layer C2 222 from outside to inside:
[0053] The transition layer C1 221 is mainly composed of titanium carbonitride TiC x1 N y1 O z1 Composition (specifically TiC 0.5 O 0.5 ), x1, y1, and z1 respectively represent TiC x1 N y1 O z1 Th...
Example Embodiment
[0066] Example 2:
[0067] Kind of like figure 1 The cutting tool with improved coating structure of the present invention shown has the same coating structure, composition and micro composition as the cutting tool in Example 1, except that the outer layer α-Al 2 O 3 It is slightly different from Example 1. In this embodiment, the thickness d of the outer layer D is 2 μm, and the average grain size S is 0.4 μm. The preparation method of this embodiment 2 is basically the same as that of embodiment 1, and only needs to be adapted to the process parameters.
