초록

In one aspect, the present invention provides coated cutting tools comprising a PcBN substrate wherein a layer of single phase α-alumina is deposited by chemical vapor deposition directly on one or more surfaces of the substrate.

대표청구항 ▼

1. A coated cutting tool comprising: a substrate comprising greater than 80% weight percent polycrystalline cubic boron nitride (PcBN); anda coating adhered to the substrate, the coating comprising a layer of single phase α-Al2O3 deposited by chemical vapor deposition directly on a surface of the substrate, wherein the coating has a critical load (Lc) of greater than 65 N. 2. The coated cutting tool of claim 1, wherein the substrate comprises at least 90 weight percent PcBN. 3. The coated cutting tool of claim 1, wherein the layer of single phase α-Al2O3 has a thickness of at least about 2 μm. 4. The coated cutting tool of claim 1, wherein the layer of single phase α-Al2O3 has a thickness ranging from about 2 μm to about 20 μm. 5. The coated cutting tool of claim 1, wherein the layer of single phase α-Al2O3 has an average grain size ranging from about 0.2 μm to about 5 μm. 6. The coated cutting tool of claim 1, wherein the layer of single phase α-Al2O3 has an average grain size ranging from about 0.5 μm to about 2 μm. 7. The coated cutting tool of claim 1, wherein grains at the surface of the single phase α-Al2O3 layer display a polyhedral morphology. 8. The coated cutting tool of claim 1, wherein grains at the surface of the single phase α-Al2O3 layer have an aspect ratio greater than about 2 in a plane arallel to the surface. 9. The coated cutting tool of claim 1, wherein the coating has a critical load (Lc) greater than 70 N. 10. The coated cutting tool of claim 1, wherein the coating further comprises a layer of MOxCyNz deposited by chemical vapor deposition over the single phase α-Al2O3 layer, wherein M is a metal selected from the group consisting of metallic elements of Groups IVB, VB and VIB of the Periodic Table and x+y+z=1. 11. The coated cutting tool of claim 1, wherein the coating has a nanohardness of at least about 23 GPa. 12.

A coated cutting tool comprising: a substrate comprising greater than 80% weight percent polycrystalline cubic boron nitride (PcBN); anda coating adhered to the substrate, the coating comprising a layer of single phase α-Al2O3 deposited by chemical vapor deposition directly on a surface of the substrate, wherein grains at the surface of the single phase α-Al2O3 have an aspect ratio of at least 5 in a plane parallel to the surface. 15. The coated cutting tool of claim 14, wherein the aspect ratio is at least 10. 16. The coated cutting tool of claim 14, wherein the coating has a critical load (Lc) greater than 70 N. 17. The coated cutting tool of claim 14, wherein the coating has a thickness of 2-20 μm. 18. The coated cutting tool of claim 14, wherein the coating has a nanohardness of at least about 23 GPa. 19. The coated cutting tool of claim 14, wherein the coating has a modulus of at least about 380 GPa. 20. The coated cutting tool of claim 14, wherein the coating further comprises a layer of MOxCyNz deposited by chemical vapor deposition over the single phase α-Al2O3 layer, wherein M is a metal selected from the group consisting of metallic elements of Groups IVB, VB and VIB of the Periodic Table and x+y+z=1.
