ARTIFICIAL JOINT OF A PROSTHESIS |
摘要 |
Prostheses with artificial joints have only a few metallic and ceramic materials whose compatibility with human or animal tissue has been established. These materials, however, cannot be combined with one another in any manner if a friction pairing occurs as a result, for example, in the case of artificial joints. With artificial joints, joint partners are required to have good mechanical properties as well as tribological properties. According to the invention, a sintered material is thus provided which is comprised of zircon oxide with an addition of 0.1 to 40 wt. % aluminum oxide. This sintered material enables an artificial joint of a prosthesis whose other ceramic materials are comprised of aluminum oxide or zircon oxide with the given proportions of aluminum oxide to be assembled with joint partners. |
