Abstract: In one aspect, cobalt-based alloys are described herein comprising composition and microstructure permitting a balance of hardness, toughness and wear resistance desirable for wood cutting applications. A cobalt-based alloy comprises a chromium rich carbide phase in an amount of 15-30 volume percent, a tungsten-rich phase in an amount of 9-15 volume percent and a balance of cobalt-rich solid solution matrix comprising nickel, chromium, vanadium and tungsten.

Abstract: Cobalt-based alloy compositions are described herein having properties compatible with thermal spray and sintering techniques. Such alloy compositions can provide claddings to a variety of metallic substrates having complex geometries, wherein the claddings exhibit desirable density, hardness, wear resistance and corrosion resistance. Briefly, an alloy composition described herein comprises 15-25 wt. % chromium, 15-20 wt. % molybdenum, 0-15 wt. % tungsten, 10-20 wt. % nickel, 2.5-3.5 wt. % boron, 2.5-4.5 wt. % silicon, 1-2 wt. % carbon and the balance cobalt, wherein a ratio of boron to silicon (B/Si) in the alloy composition ranges from 0.5 to 1.0.

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.
