ABSTRACT:
Erosion and abrasion resistant refractory metal carbide articles are provided having multiphase alloy of borides including titanium boride, binder metal boride, and titanium-binder metal-refractory metal borides by diffusion of titanium initially to convert the refractory metal carbide to its constituents which are then reacted with boron, forming a new added surface in replacement of the original article surface, and bridging the original surface locus.
