Summary: | The present disclosure discloses a high-entropy alloy powder for laser cladding and a use method thereof. The alloy powder is CoCrFeMnNiCx, and x has a value of 0.1-0.15. The specific method includes: subjecting a 45 steel substrate to surface pretreatment, mixing the weighed CoCrFeMnNi high-entropy alloy powder with different content of a nano-C powder uniformly and pre-placed on the pre-treated substrate surface to form a prefabricated layer, then placing the prefabricated layer at 80-90° C. for constant temperature treatment for 8-12 h, and under a protective atmosphere, subjecting the cladding powder to laser cladding on the surface of the 45 steel. The method of the present disclosure prepares a CoCrFeMnNiCx high-entropy alloy coating with performance superior to the CoCrFeMnNi high-entropy alloy coating. |
