Abstract: PURPOSE: A cemented carbide-steel assembly and a method for manufacturing the same are provided to prevent delamination or cracking on the boundary surface between a steel layer and a cemented carbide layer by bonding the steel layer and the cemented carbide layer with superior bonding strength. CONSTITUTION: A method for manufacturing a cemented carbide-steel assembly is as follows. A sintering apparatus having a mold and a punch part which applies current and pressure to a material put in the mold is prepared. A raw material is put in the mold of the sintering apparatus so that a compound sintered layer(30), which is formed of compound powder including cemented carbide powder and steel powder, is formed between a cemented carbide layer(10) and a steel layer(20). Current and pressure are added to the raw material to generate spark plasma, thereby sintering the raw material.
