Abstract

This paper reports for the first time the use of field-assisted sealing for bioactive implant coating applications. Field-assisted sealing (anodic bonding) of bioactive glass particles to bioinert glass enamel coating of titanium implant was investigated. Biocompatible titanium oxide interlayer was fabricated by deep thermal oxidation of 80 nm thick Ti thin film previously vacuum evaporated onto polished bioactive glass surface. Bioactive glass particle was anodically bonded via the interlayer to polished surface of bioinert glass enamel coating vacuum deposited onto Ti plate at 860°C. A total of 20 min preheating time with constant temperature increase rate, 5 min bonding time, and 100 V DC voltage were applied during field-assisted bond formation at 530°C in air.
