Problems solved by technology

[0008] To sum up, it can be concluded from the prior art that a coating containing Ti, Al, Si, N and other elements can be prepared by doping silicon into fcc-AlTiN by PVD method, but since the Al content cannot exceed 67%, thus limiting the improvement of the coating's oxidation resistance and wear resistance
High-aluminum fcc-AlTiN coatings can be prepared by CVD, but because the coating is a metastable phase structure, it is prone to strip decomposition under long-term high-temperature cutting to form hcp-AlTiN, resulting in a decrease in coating hardness and wear resistance decreased sex

Abstract

The present invention discloses a cutting tool and its manufacturing method, including a single layer or multi -layer coating on the base and coating on the base. x SI y TI 1‑x‑y ) N coating, wheren, x ≥ 0.70, 0 <y ≤0.1.The invention cutting tool is coated (AL x SI y TI 1‑x‑y ) N coating, while ensuring the high aluminum of coating, due to the incident of SI elements, the amorphous parcel nanocrystalline structure is formed, the coating tissue is refined, the high temperature hardness of the coating is improved, and the coating antioxidant is not reduced.At the same time, the wear resistance of the coating is improved.

Description

technical field [0001] The invention belongs to the field of material processing, and in particular relates to a cutting tool and a manufacturing method thereof. Background technique [0002] The modern manufacturing industry is developing in the direction of high efficiency and environmental protection. With the increasing proportion of high-speed and dry cutting, the performance requirements of cutting tools are also getting higher and higher. Today, the performance of traditional carbide cutting tools can no longer adapt to high-speed, dry cutting. Therefore, various technologies for coating cemented carbide tools to improve their cutting performance have been developed one after another. In order to meet the needs of high-speed and dry machining and achieve better performance, the composition of the coating is becoming more and more complex, and the structure of the coating has also developed from a simple single coating to a variety of complex structures. [0003] For...
