“…One way of combining the positive properties of both materials are mixed-oxide ceramics (ATZ, ZTA). Another way is the so-called gradient ceramic, which shows a defined gradient of concentration and properties within the ceramic implant [1,2,3,4,5]. So it is closed to provide the tribologically stressed parts (e.g.…”

Abstract. A new ceramic material for orthopaedic applications was investigated. Therefore a gradient ceramic was prepared with a zirconia gradient within an alumina matrix by an infiltration process. This material was characterized regarding its microstructure, stress distribution inside the ceramic, zirconia phase analysis and strength. It could be shown that the flexural strength of the new ceramic is twice as high as of pure alumina ceramic. By this and the low monoclinic zirconia content this material offers a potential for its use in high load bearing implants like hip heads for joint endoprostheses.

“…A way of combining the positive properties of Al 2 O 3 (wear resistance, hydrothermal stability, hardness) with those of ZrO 2 (strength, fracture toughness) are the mixed-oxide ceramics (ATZ, ZTA). Another way of making implants with favourable wear characteristics and strengths are materials with defined concentration and property gradients [1,2,3,4]. So it is reasonable to provide the tribologically stressed parts with a high Al 2 O 3 content and the parts that are exposed to high mechanical strain with a high ZrO 2 content.…”

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.
