文摘
- •
All manufactured alloys are biocompatible and promote strong cell adhesion.
- •
The elastic modulus of all evaluated alloys is lower than 85 GPa.
- •
Fe and Si additions increase microhardness, yield stress and ultimate strength.
- •
Fe and Si additions promote the osteogenic differentiation (collagen I production).
- •
TNZT–2Fe–0.5Si alloy proves the best mechanical and biological properties.
