Abstract
A method to form a composite wear resistant die face of titanium carbide, tungsten carbide/cobalt alloy or similar material having a metal backing which is readily bondable to a substrate. Since sintered powdered metallurgy wear resistant materials are difficult to solder or braze directly to a die by conventional methods, a steel backed composite is formed by hot isostatic pressing of the wear resistant material to both sides of a steel substrate and this composite is cut through the middle of the steel blank to formed separate steel backed wear resistant die facing plates, especially useful for pelletizers.
