ABSTRACT:
A wear-resistant annular insert which may be used as a wire drawing die, includes an annular exterior layer and an annular interior layer, containing diamond or cubic boron nitride crystals, bonded to the interior of the annular exterior layer by a .beta.-silicon carbide and silicon matrix. The insert is formed by preparing a first dispersion of carbon fiber, carbon black and filler in a temporary binder such as paraffin, and preparing a second mixture of the crystal material and carbon black in the temporary binder. The first and second mixtures are compressed in a mold such that the first and second mixtures form the exterior and interior layers, respectively. The layers are then heated to allow for the removal of the temporary binder and the infiltration of liquefied silicon. The layers are then sintered to produce the annular insert.
