Embodiment Construction

[0038] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments, wherein the methods are conventional methods unless otherwise specified, and the raw materials can be obtained from open commercial channels unless otherwise specified.

[0039] When multi-arc ion plating technology is used to prepare multi-dimensional gradient coatings on WC-TiC-Co hard alloy tools, the multi-dimensional gradient coatings are divided into Ti-Zr-N coatings, Ti-Zr transition layers and interface Three parts of the transition layer; among them, the Ti-Zr-N coating includes inner, middle and outer layers, and the Ti-Zr transition layer includes inner, middle and outer layers. The distribution of different deposition layers on the tool substrate is detailed in figure 2 ;

Abstract

The invention relates to a preparation method of a multi-dimensional gradient coating layer on a surface of a cutter, and belongs to the technical field of metal cutting and cutter coating. The multi-dimensional gradient coating layer adopts the same coating material system; and components and performances of each deposition layer are controlled through controlling process parameters of the deposition process, so that the components and the mechanical performances of each deposition layer can realize continuous transition from inner layer to outer layer, the mutation of interface element components, physical performances and mechanical performances is prevented, the stress concentration caused by mismatch on interfaces is effectively relieved, and the coating reliability in the use processis improved. The outermost layer of the multi-dimensional gradient coating layer prepared by the method is high in hardness, so that the surface wear resistance can be effectively improved; the interfaces of internal deposition layers are high in bonding strength to effectively improve the coating capacity of resisting such destructions and failures as stripping / layered stripping; and the methodcan be widely applied to the coating treatment field of cutting tools and wear resisting surfaces.
