The invention belongs to the field of hot spraying, and discloses an arc sprayed cored wire suitable for re-melting. The powder core comprises the components of, by mass, 6-15% of Ni, 5-13% of Cr, 4-8% of Al, 5% of B, 3% of Nb, and 1-3% of mixed rare earth nickel powder. The mixed rare earth nickel powder component is composed of, by mass, 60% of Ni and 40% of mixed RE. The mixed RE is composed of, by mass, 25-28% of La; 48-52% of Ce, 14-17% of Nb, and 4-6% of Pu. The balance of the powder core is Fe. An arc sprayed coating provided by the invention has an average Vickers hardness of 530HV0.1, an average bonding strength of 38MPa, an average porosity of 14.2%, and an oxide content of 8.72%. After a re-melting treatment upon the sprayed coating, an average Vickers hardness of the re-melted layer is improved to 770HV0.1, and the layer substantially forms metallurgical bonding with a substrate. After re-melting treatment, the wire material coating has good wear resistance, erosion resistance, and loading resistance. The cored wire provided by the invention can be used in surface treatments of parts with requirements on high impact resistance, large alternating load, and high bonding strength in the fields of engineering machinery, mining machinery, and automobile industry.
