Abstract:

Cobalt Chrome material, CoCr, has been used for orthopaedic implants and joint replacement for many years with great success. This alloy has been qualified for use in the body and is used in applications where wear resistance and mechanical properties are of great importance. As a result, these components are usually thermally processed using Hot Isostatic Pressing (HIP).Recently, focus has shifted away from the use of Cobalt in the body due to sustainability and cancer concerns, and as a result, other materials are being reviewed and applied for future products. As part of this, existing alloys are being considered, with innovative heat treatments to improve wear resistance.This paper will present an overview of the ongoing challenges along with options for tailored HIP cycles that can improve wear resistance of Titanium alloys.
