ABSTRACT:
A joint prosthesis having two mutually articulating components that are made of a metal alloy. One of the components is made of an alloy having a low carbon content (0.03 to 0.10 wt. %) and the other component is made of an alloy having a high carbon content (0.18 to 0.35 wt. %). The articulating components may be, for example, a hip head prosthesis and an acetabular cup prosthesis.
