摘要
To improve the osseointegration and biological performance of biomedical titanium, hydroxyapatite (HA) was coated onto chemically modified titanium (Ti) using a novel and fast biomimetic route which incorporated supersaturated calcification solutions (SCS). As a result, it is possible to obtain HA coatings on both acid and base chemically-modified titanium surfaces within 2 h using SCS. After coating, acid etched and heat treated Ti exhibited a fine and homogenous coating of hydroxyapatite crystals that did not change morphology after 4 h. Alkaline-modified Ti showed a denser and thicker nano-sized hydroxyapatite layer (particle size about 100 nm) at 2 h due to the presence of hydrogen sodium titanate. Therefore, no heat treatment was necessary to induce HA precipitation.
