Bio-tribo-corrosion resistant 3D Printed Composites for Load-bearing Implants
Among load-bearing implants, total hip arthroplasty (THA) is probably the most clinically successful intervention. CoCrMo alloy, a wear resistant material of choice, is typically used in femoral heads for THAs. In vivo life of THAs are often reduced due to debris generation, and Co and Cr metal ion release from modular junctions. Management of taper corrosion from trunnions of CoCrMo head and Ti6Al4V stems remain a serious challenge today. Taper corrosion happens primarily due to mechanically assisted crevice corrosion (MACC) along with fretting and galvanic corrosion, and leads to adverse local tissue reactions (ALTR), an immune- mediated biological reaction due to elevated Co and Cr ions.…
