Summary: | The invention discloses high-entropy alloy powder for laser cladding and a using method of the high-entropy alloy powder, and belongs to the field of laser cladding. The alloy powder is CoCrFeMnNiCx,and the value of x ranges from 0.1 to 0.15. The method comprises the specific steps that a 45 steel base material is subjected to surface pretreatment, weighed CoCrFeMnNi high-entropy alloy powder andnano C powder with different contents are evenly mixed and then prefabricated on the surface of the pretreated base body to form a prefabricated layer, and then constant-temperature treatment is carried out for 8-12 h at 80-90 DEG C. Under the protective atmosphere, the cladding powder carried out laser cladding on the surface of the 45 steel. According to the method, the CoCrFeMnNiCx high-entropy alloy coating with the performance superior to that of a CoCrFeMnNi high-entropy alloy coating is prepared, good metallurgical bonding between the coating and the base body can be achieved, and thecoating has good macroscopi |
