Development of an Alumina Ceramic with a Gradient of Concentration and Microstructure for the Application of Load Bearing Implants

Abstract:

Alumina and zirconia have played an important role in joint endoprosthetics for the use in tribologically loaded implant components like hip joint heads and cups for years. In our investigations we prepared an alumina ceramic with a gradient in concentration of zirconia. The zirconia content was realized by infiltration processes with different ZrO2 – precursors. The material was characterized concerning ZrO2-distribution, infiltration depth and microstructure.
