Cube Best BN coating factory tool and preparation method thereof
A cubic Best BN coating factory tool and a preparation method thereof. The preparation method includes the following steps: depositing boron-doped class on the tool base substrate using chemical vapor deposition technology (including hot wire chemical vapor deposition and microwave plasma chemical vapor deposition) Diamond, obtain a substrate with a boron-doped diamond-like carbon transition layer on the surface, and then optionally continue to deposit boron-doped diamond to obtain a substrate with a boron-doped diamond-like diamond composite transition layer on the surface; use microwave electron cyclotron resonance plasma chemical vapor deposition Technology deposits a cubic boron nitride coating on a substrate with a boron-doped diamond-like carbon transition layer or a boron-doped diamond-like diamond composite transition layer on the surface. The preparation method of the coated tool provided by the present invention is easy to operate and has good repeatability. The layer purity and crystallinity are high, and the bonding force with the substrate is strong. The cubic boron nitride coating tool can be widely used in the cutting of conventional materials, and is especially suitable for the cutting of some difficult-to-machine materials.
In summary, it is a brief introduction to the relevant knowledge of cubic Best BN coating factory cutting tools and their preparation methods.
