Abstract

The invention provides a multi-principle element alloy coating for a cutting tool and a preparation method thereof, and belongs to the field of metal materials and preparation thereof. The chemical formula of the multi-principle element alloy is AlxCoCuMnyNiZnz, wherein x is greater than or equal to 0.1 and is less than or equal to 1.3; y is greater than or equal to 0.1 and is less than or equal to 1.3; z is greater than or equal to 0.1 and is less than or equal to 1.3; x / (x+y+z+3) is greater than or equal to 0.02 and is less than 0.30; y / (x+y+z+3) is greater than or equal to 0.02 and is lessthan 0.30; and z / (x+y+z+3) is greater than or equal to 0.02 and is less than 0.30. The components of the multi-principle element high-entropy alloy material prepared by the preparation method are consistent with the raw material components, so that the multi-principle element high-entropy alloy material can be effectively combined with a plurality of substrate materials; the requirements on different tool performance changes can be met by finely adjusting the multi-principle element alloy components and structures according to specific use conditions of a workpiece; the equipment is simple; the production efficiency is high; and the application range is wide.

Description

technical field [0001] The invention relates to the field of metal materials and their preparation, in particular to a multi-principal alloy coating for cutting tools and a preparation method thereof. Background technique [0002] The machinery manufacturing industry is the material basis of national economic and social development, and an important symbol to measure the comprehensive strength of a country. Cutting is an important part of machinery manufacturing. High-speed machining has the characteristics of high production efficiency, high machining accuracy, and good surface quality. It is the development direction of cutting machining technology and can be widely used in automobiles, molds, machine tools and other fields. However, for a long time, Chinese enterprises have mainly purchased equipment, ignoring the research and accumulation of basic theory and processing technology, which has affected the promotion and application of high-speed cutting processing technolo...
