1. A wear resistant device comprising:
a substrate comprised of a first metallic material; and a wear resistant layer disposed on the substrate, the wear resistant layer being comprised of a matrix of a second, different metallic material extending continuously between a first surface at the substrate and a second, opposite surface, particulates dispersed throughout the matrix, and a boron material distributed exclusively within a surface zone of the matrix extending from the second surface to a location intermediate of the second surface and the first surface, the particulates being selected front the group consisting of oxide particulates, carbide particulates and combinations thereof, the carbide particulates being selected from a group consisting of silicon carbide, chromium carbide, diamond, and combinations thereof, and the second metallic material being selected from a group consisting of cobalt, nickel, cobalt-phosphorus, nickel-phosphorous, nickel-tungsten, and combinations thereof.
