Alumina (Al 2 O 3 ) bearings in total hip arthroplasty lead to low wear rates, but catastrophic failure of Al 2 O 3 femoral heads, while rare, remains a concern. In the present work, a composite of Al 2 O 3 and niobium (Nb) was tested in vitro for potential use as an alternative femoral head materia
