Abstract

The invention belongs to the technical field of mechanical cutting tool manufacture, and in particular, relates to a micro-texture ZrVSiN self-adaptive coated cutting tool and a preparation process thereof. A basal body material of the cutting tool is ceramics or a hard alloy, and a micro-texture is processed on a basal body of a front tool face of the cutting tool; coating layers on the surface of the cutting tool is provided with a ZrVSiN self-adaptive coating layer and a Zr transition layer from top to bottom. The application of the ZrVSiN self-adaptive coating layer can make a layer of VO2, V2O3, V2O5 and other vanadium oxide products having a lubrication effect formed on the surface of the cutting tool through a reaction of V in a cutting process with oxygen in air, and a glaze layer with V2O5 glass phase is produced in quantity along with rising of the temperature, so that the friction of a tool-chip contact area is reduced; V2O5 is a liquid phase when the temperature is 500 DEG C or more, the micro-texture can store the V2O5 liquid-phase lubricant, and loss of the vanadium oxide products having the lubrication effect is prevented. The cutting tool can be widely applied in dry cutting and cutting processing of hard-to-process materials.

Description

[0001] 1. Technical Field [0002] The invention belongs to the technical field of mechanical cutting tool manufacturing, and particularly relates to a ZrVSiN adaptive coating tool and a preparation process thereof. [0003] 2. Background technology [0004] With the rise of green manufacturing technology, people have gradually realized that dry cutting can improve the working environment of workers, and because the use of cutting fluid is discarded, the use cost of cutting fluid and the cost of waste liquid treatment are greatly reduced. In the dry cutting process, the cutting tool does not have the cooling and lubrication of the cutting fluid, and the processing conditions are bad, which causes severe tool wear and reduced tool life. Therefore, in order to meet the requirements of dry cutting, it is necessary to design an adaptive tool to improve the working conditions of the tool in the process of machining the workpiece. [0005] Surface texture technology is an effective method t...
