Problems solved by technology

However, at present, the overall material of the turning tool is made of materials that meet the above mechanical properties, and the cost is very high. If the metal alloy powder specially used for laser cladding of the turning tool can be provided, then laser cladding can be used to improve the mechanical properties of the turning tool. At the same time, it can also reduce the cost of turning tools

Abstract

The invention discloses cobalt-based metal ceramic alloy powder exclusively used in laser cladding of a turning tool. The cobalt-based metal ceramic alloy powder is composed of the following ingredients in percentage by weight: 11-14% of silicon carbide, 0.1-0.3% of carbon, 5-7% of calcium fluoride, 18-28% of chromium, 2-4% of boron, 0.2-0.4% of vanadium, 5-8% of iron, 4-6% of silicon, 13-16% of molybdenum, and the balance of cobalt. The cobalt-based metal ceramic alloy powder is exclusively used in laser cladding of the turning tool, improves the metal structure density of the turning tool, reduces the defects such as gas pores, cracks and shrinkage cavities of the cladding layer, and improves the wearing resistance, rigidity, heat resistance and strength of the turning tool, and meanwhile, the cost is reduced.

Description

technical field [0001] The invention relates to an alloy powder, in particular to a cobalt-based cermet alloy powder specially used for laser cladding of turning tools. Background technique [0002] Laser has the characteristics of high brightness, high directionality, high monochromaticity and high coherence, and is now being used in more and more fields. Laser cladding is one of the surface treatment technologies. In a nutshell, the principle of laser cladding is to use high-energy laser beams to irradiate the surface of metal materials, the surface of the substrate is melted rapidly, the liquid metal forms a small-scale molten pool, and new powder materials are filled at the same time. , the original metal material is mixed with the added powder to form a new layer of liquid metal. After the laser beam passes through, the liquid metal layer is rapidly cooled to form a solid cladding layer on the metal surface. A turning tool is a tool with one cutting part for turning. ...
