摘要：
A joint prosthesis comprises a first component having a bearing surface and a second component having a bearing surface arranged to articulate with the bearing surface of the first component, said bearing surfaces of the first and the second component thus forming a bearing couple. The bearing surfaces consist of a silicon carbide whisker reinforced alumina. Thus, a bearing couple with low wear, low friction and high hardness is provided.
