Problems solved by technology
[0003] The distributor is the core equipment of the copper smelting industry. It was mostly imported from abroad before. There is no alloy powder for laser cladding of the copper smelting distributor in China. The alloy powder usually used is not suitable for the copper smelting distributor because it needs high wear resistance. Heat and Corrosion Resistance

A disclosed laser cladding powder applied to copper smelting distributor is composed of the following chemical compositions in percent: 2.5% of C, 22% of Cr, 2% of Nb, 3.5% of Mo, 2.5% of B, 2% of Si, and the balance Fe. A preparation method of the powder comprises putting the raw materials with the above ratio in a vacuum environment, melting, performing water atomization processing, screening, and controlling the granularity to be 150-53 mu m. The laser cladding powder helps to improve the plasticity and the toughness of a cladding layer, also reduce the thermal expansion coefficient of the cladding layer, reduce residual stress and eliminate stress concentration, thereby eliminating cracks and shrinkage porosity.
Description
technical field [0001] The invention relates to an alloy powder, in particular to a laser cladding powder for a copper smelting distributor. Background technique [0002] Laser cladding is one of the surface treatment technologies. The principle of laser cladding is to use a high-energy laser beam to irradiate the surface of the metal material, the surface of the substrate is rapidly melted, the liquid metal forms a molten pool, and the metal powder material is added at the same time. The metal powders fuse with each other 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. With the continuous improvement of laser power and stability, it has been rapidly promoted and applied. Laser cladding technology can be widely used in aviation, mining, metallurgy, petrochemical and other fields. [0003] The distributor is the core equipment of the copper smelting indu...
