ABSTRACT:
In a method of joining a metal matrix composite (cermet) or ceramic tool material 1 to a metallic holder 2 by diffusion bonding through an intermediate metallic layer, the tool material 1 includes at least one carbide, nitride or boride in the matrix. In one example, the tool material includes titanium carbide and titanium nitride in the metal matrix. The intermediate metallic layer is chosen from a group consisting of nickel, titanium and tungsten. The tool holder metal 2 is a ferrous alloy. The intermediate metallic layer is placed between the tool material and the metallic holder, and heat and pressure are applied for a controlled period to diffusion bond the tool material to the metallic holder. Articles made by the method include a blank holder, a punch, a die and various wear surfaces of a continuous extrusion apparatus.
