Sol-gel deposition of hydroxyapatite coatings on porous titanium for biomedical applications

The stress shielding and the poor osseointegration in titanium implants are still problems to be resolved. In this context, this work proposes a balanced solution. Titanium samples were fabricated, with a porosity of 100–200 μm of pore size employing space-holder technique (50 vol% NH4HCO3, 800 MPa at 1250 °C during 2 h under high vacuum conditions), obtaining a good equilibrium between stiffness and mechanical resistance. The porous titanium...
