Abstract Scope |
A first-of-a-kind table-top joint simulator was designed and manufactured to better simulate and test volumetric tribo-corrosion of femoral heads. More specifically, the simulator mimics the gait-like motion of the hip joint. Ti6Al4V+ZTA+HA metal matrix composite femoral heads were produced via additive manufacturing. The ability to move into volumetric articulating-based testing has shown promising results for improving these innovative materials. The objective was to address the shortcomings of currently used metallic biomaterials in load-bearing orthopedic devices, where corrosion and wear are of concern. The poster will display the system design, AM-produced femoral heads, and results related to volumetric tribo-corrosion in cell media of Ti6Al4V+ZTA+HA metal matrix composites articulating against medical-grade UHMWPE. |
