Technical Field
The invention relates to the technical field of metal powder, in particular to cobalt-based metal powder.
Background
Laser has the characteristics of high brightness, high directivity, high monochromaticity and high coherence, is being used in more and more fields at present, and laser cladding is one of surface treatment technologies. In summary, the principle of laser cladding is that a high-energy laser beam is used to irradiate the surface of a metal material, the surface of a substrate is rapidly melted, the liquid metal forms a small-scale molten pool, and a new powder material is filled into the molten pool, wherein the original metal material and the added powder are mixed with each other to form a new liquid metal layer. After the laser beam passes through, the liquid metal layer is rapidly cooled, thereby forming a solid cladding layer on the metal surface. A turning tool is a tool for turning having a cutting portion. When the lathe tool works, the contact turning between the lathe tool and a workpiece generates a large amount of heat. Therefore, the turning tool has a high requirement on the material of the turning tool, and the turning tool specifically comprises the following components: 1) high hardness and good wear resistance: 2) good heat resistance: 3) high strength.
