This invention provides a composite material that is durable in a hot environment and easily produced. The composite material according to the invention has an overlaid part comprising high-melting-point metal in at least a part on the surface of a low-melting-point alloy member having a melting point of 1600° C. or lower. The overlaid part comprising high-melting-point metal comprises high-melting-point metal particles comprising high-melting-point metal elements having a melting point of 2400° C. or higher scattered therein and comprises the high-melting-point metal elements that account for 50% by mass to 95% by mass thereof.
A composite material comprising an overlaid part comprising a high-melting-point metal in at least a part on the surface of a low-melting-point alloy member having a melting point of 1600° C. or lower, wherein the overlaid part comprising the high-melting-point metal comprises high-melting-point metal particles comprising high-melting-point metal elements having a melting point of 2400° C. or higher scattered therein and comprises the high-melting-point metal elements in a range of 50% by mass to 95% by mass.
A method for producing a composite material comprising a step of forming an overlaid part comprising a high-melting-point metal comprising high-melting-point metal particles comprising high-melting-point metal elements in which the high-melting-point metal particles comprising the high-melting-point metal elements having a melting point of 2400° C. or higher are scattered by feeding starting powders comprising the high-melting-point metal powders having a melting point of 2400° C. or higher to the surface of the low-melting-point alloy member while applying a thermal energy to the surface of a low-melting-point alloy member having a melting point of 1600° C. or lower to melt the low-melting-point alloy member.
