Titanium-based composites with in-situ calcium and phosphor phases were prepared by powder metallurgy processing with titanium and hydroxyapatite (HA) powders. The mixtures were obtained in a friction mill with alcohol for 5 h, dried in a rotating evaporator, pressed at 600 MPa and sintered at 1200...
