摘要： A method is provided of producing a hardmetal-bonded metal component with an enhanced bond strength. The method comprises the steps of providing an iron-based metal body, mixing and compressing raw material powder of hardmetal and binder powder containing nickel, silicon and boron into a preform, heating and sintering the preform, and applying heat to the sintered body and the iron-based metal body under a state that the sintered body is brought into contact with the iron-based metal body, to thereby cause the sintered body to be bonded to the iron-based metal body. The sintered body and the iron-based metal body are thermally treated at a temperature of 1,000 to 1,200° C. for 30 or more minutes so that boron present in the sintered body is infiltrated into grain boundaries of the iron-based metal body to form a plurality of boride spikes in a bonding interface.
