| Outline of Final Research Achievements |
Ceramic coating layers of amorphous calcium phosphate (ACP) and TiO2 were prepared on Ti, and their antibacterial activities were evaluated. Ag-containing ACP layers fabricated by RF magnetron sputtering exhibited antibacterial activity through the continuous release of Ag ions, caused by the resorbability of ACP. TiO2 layers fabricated by thermal oxidation processes showed photodegradation of organic compounds and antibacterial activity under both UV- and visible-light irradiation. The introduction of Au into TiO2 layers from Ti-Au alloy substrates contributed to the expression of visible-light response. The optimized fabrication processes provided the coating films with both the bone forming ability and antibacterial activity.
