Abstract: A surgical implant component comprising an implant component body manufactured from a Co-based substrate alloy comprising Co, Cr, Mo, Si, and C, and a coating on a bone-ingrowth surface of the component body manufactured from a Co-based coating alloy comprising Co, Cr, Mo, Si, C and B. The coating is a network of fused particles of the Co-based coating alloy with spherical particles, irregular aspherical particles, and between about 35 and about 70 volume % porosity. A method of manufacturing the foregoing surgical implant component.

Abstract: A surgical implant component comprising an implant component body manufactured from an alloy comprising from about 23 to about 33 wt % Cr, from about 8 to about 20 wt % Mo, from about 0.05 to about 1.5 wt % Si, from about 0.35 to about 3.5 wt % C, from about 40 to about 60 wt % Co, and incidental impurities. The implant component alloy has an atomic % ratio of (Cr+Mo+Nb)/Co of at least 0.59, a matrix metallurgical microstructure comprising between about 45% and about 85% by volume face-centered cubic structure, and between about 15% and about 55% by volume hexagonal close-packed structure; and a Rockwell C hardness of greater than 35. A method for manufacturing a surgical implant component body for a surgical implant by a manufacturing method selected from the group consisting of casting, forging, and powder metallurgy pressing-plus-sintering from an alloy.

Abstract: Forming a wear- and corrosion-resistant coating on an industrial component such as a chemical processing or nuclear power valve component by applying a cobalt-based dilution buffer layer to an iron-based substrate by slurry coating, and then applying by welding a cobalt-based build-up layer over the cobalt-based dilution buffer layer. An industrial component having a dilution buffer layer and a welding build-up layer thereover.
