Hydroxyapatite Formation on Bioactive Glass Coated Titanium

초록

Two different bioactive glasses were coat in a titanium to give it a bioactivity, and then the bonding characteristics between a titanium and a coated layer and the hydroxyapatite formation in a simulated body fluid(SBF) on the coated specimens were studied. Ti₅Si₃ was found at the interface between titanium and glass coat in the groundcoat layer, and this enhanced the titanium-glass bonding. The hydroxyapatite formation was observed only on the covercoat fired under 800℃, which is in an amorphous phase, and was retarded for the sample fired over 850℃, which contains an oxyapatite.
