Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants

Advanced Healthcare Materials, EarlyView.
We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.
