Abstract

The invention discloses a cobalt based metal powder. The metal powder is prepared from, by weight, 13-15% of tungsten carbide, 0.2-0.4% of carbon, 2-4% of calcium fluoride, 2-4% of silicon nitride, 18-23% of chromium, 2-4% of boron, 0.2-0.4% of vanadium, 5-8% of iron, 4-6% of silicon, 9-12% of molybdenum, 1.2-1.6% of manganese, and the balance cobalt. The cobalt based metal powder can be sufficiently fused with a lathe tool base material, the ingredients can be evenly distributed into a cladding layer, ultrahigh hardness ceramic granules are adopted for improving the harness of a lathe tool, in addition, some micro elements are selected for improving the corrosion resistance, strength and heat resistance of the lathe tool, and therefore the cobalt based metal powder is used for performinglaser fusion covering on the lathe tool, and the cost is lowered while the mechanical performance of the surface of the lathe tool can be improved.

Description

technical field [0001] The invention relates to the technical field of metal powders, in particular to a cobalt-based metal powder. Background technique [0002] Laser has the characteristics of high brightness, high directivity, 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, and the liquid metal forms a small-scale molten pool, and at the same time, new powder materials are filled. , 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 cools rapidly, thus forming a solid cladding layer on the metal surface. A turning tool is a tool with one cutting part for turning. During work, the contact turnin...
