Abstract

The invention discloses a carbide-reinforced nickel-based welding wire for laser cladding. The carbide-reinforced nickel-based welding wire comprises a flux core and a welding scale, wherein the flux core is composed of the following components including, by mass, 0.5%-1.0% of C powder, 10.0%-30.0% of Cr powder, 5.0%-10.0% of ferrosilicon powder, 3.0%-9.0% of B powder, 5.0%-10.0% of ZrO2 powder, 1.0%-3.0% of Ce2O3 powder and the balance Ni powder, and the sum of the mass percentages of the components is 100%. The welding wire is specially used for a wire feeding laser cladding system, and a cladding layer using the flux-cored wire is high in hardness and good in wear resistance. The invention further discloses a preparation method of the ZrC and Ce2C3 reinforced nickel-based welding wire for laser cladding.

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to a carbide-reinforced nickel-based welding wire for laser cladding, and also relates to a preparation method of the carbide-reinforced nickel-based welding wire for laser cladding. Background technique [0002] Laser cladding can significantly improve the surface properties of materials, restore the size of workpieces or repair worn materials. It has the characteristics of high efficiency, fast speed, and environmental protection. It is widely used in almost the entire machining industry. Laser cladding materials largely determine the performance of the cladding layer. Laser cladding materials can be divided into powder, wire and rod according to different shapes. Nowadays, almost all powder materials are used for laser cladding. Laser cladding can be divided into prefabricated powder feeding and powder feeding cladding according to different powder feeding methods. The ...
