The hydrocarbon coated Ni-based alloy powder comprises components, by weight percentage, 0.1%-1% of hydrocarbon and 99%-99.9% of Ni-based alloy powder. The preparation method includes steps of A, mixing the proportional hydrocarbon and boiled purified water in a container until the hydrocarbon is pasty; B, mixing the pasty hydrocarbon with Ni-based alloy powder and stirring the same sufficiently; C, drying the mixed powder in an oven at the temperature ranging from 70 DEG C to 100 DEG C, breaking the dried mixed powder, filtering the same with a sieve of 80 meshes, and thereby obtaining the hydrocarbon coated Ni-based alloy powder.

Description

technical field [0001] The invention relates to the technical field of cermet powder processing, in particular to a hydrocarbon-coated cermet powder for laser processing and thermal spraying and a preparation method thereof. Background technique [0002] Laser material processing is a new processing method using high-energy laser beams, and it is a contemporary advanced material processing method. Laser processing has many obvious advantages over conventional processing methods, and its application range is also very wide, such as: laser cladding, laser surface alloying, etc. Laser cladding refers to the surface coating method that not only changes the microstructure of the surface layer of the material but also changes its composition by adding metal elements or alloys while melting the local surface of the material with a high-energy laser beam. Cladding also has the unique ability to directly manufacture metal parts quickly and flexibly. Laser surface alloying is the us...
