摘要:
A wear-resistant article that includes a substrate that presents a surface. The substrate has a bulk region and a surface region beginning at and extending inward from the surface toward the bulk region. There is a diffusion barrier layer on at least a portion of the surface of the substrate wherein the diffusion barrier layer is a nickel-based alloy. There is a wear-resistant cladding layer on the diffusion barrier layer wherein the wear-resistant layer contains boron. The surface region of the substrate contains no boron that has been diffused from the wear-resistant cladding layer.
