  • Application of diffusion hardened material
    Patent number: 9681955
    Abstract: An implant having components comprising an oxidized zirconium bearing surface adapted to decrease pain, lower friction, and minimize wear when coupled with natural femoral articular cartilage. The implant components also provide for reduced backside wear effects in fixed and mobile implants. The implant components further provide for more ideal wear coupling between components in mobile bearing implants.

  • Ceramic metal composite for orthopaedic implants
    Patent number: 9107980
    Abstract: The invention relates to an orthopaedic implant made of a ceramic metal composite. The composite includes one phase that is a biocompatible metal or metal alloy and a second phase of ceramic particles examples of which include carbides, nitrides and/or oxides. In some embodiments, the implant comprises a homogeneous ceramic layer as part of a multilayered composition. In some embodiments, the multilayered composition comprises a homogeneous metal layer.
