| Abstract: | Hydroxyapatite/titanium (HA/Ti) porous biocomposite scaffolds were prepared via a powder metallurgical method using NH4HCO3 as the pore-forming agent. The scaffolds induced HA formation and showed high bioactivity, and their porosity and compressive strength could be regulated by changing the NH4HCO3 dosage. When the NH4HCO3 dosage was 40.0%, the porosity was 67.0 ± 0.8%, and compressive strength was 19.0 ± 0.6 MPa, indicating the corresponding scaffold was an ideal choice for spongy bone repair. |
