Abstract:
1. 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, wherein the alloy has an atomic % ratio of (Cr+Mo+Nb)/Co of at least 0.59; wherein the implant component body has a mixed face-centered cubic (FCC) and hexagonal close-packed (HCP) 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 wherein the implant component body has a Rockwell C hardness of greater than 35; and wherein the implant component is a component of an implant for repair or replacement of a component of a knee, hip, shoulder, elbow, wrist, ankle, finger, toe or spine.
