文摘
- •
Hydroxyapatite (HA) powders in three particle size groups (< 1 μm, 1–10 μm, 100–200 μm) were synthesized.
- •
Nine iron-hydroxyapatite composites (HA content = 2.5, 5, 10 wt%) were fabricated via the powder metallurgy process.
- •
Tensile strength and ductility of the composites decreased with increasing HA content and decreasing HA particle size.
- •
In vitro corrosion rates of the composites increased with increasing HA content and decreasing HA particle size.
