Abstract Hydroxyapatite/titanium (HA/Ti) porous biocomposite scaffolds were prepared via a powder metallurgical method using NH 4 HCO 3 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 NH 4 HCO 3 dosage. When the NH 4 HCO 3 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.
