Abstract
The aim of this paper is to report the use of the anodic bonding technique to produce a modification to increase the bioactive response on titanium alloy surface by means of the bonding between a bioglass and titanium alloy. Ti alloy and bioactive glasses 52S4.6 and 45S5 were successfully bonded using anodic bonding technique for range of temperature and applied potential.Bioactive glass anodically bonded to Ti alloy results in a strong adhesion. Mechanical detachment can be performed and the fracture occurs in the glass and not at the interface. As a result small bioactive glass particles still bonded to Ti alloy surface spread to the bonding region. Bioactive in-vitro results revealed that after soaking in SBF, the Ti alloy submitted to anodic bonding and that was mechanically separated from bioglass prior to soaking in simulated body fluid solution were covered with a apatite layer in the bonding region indicating that anodic bonding technique is an effective way to produce a bioactive response on Ti alloy surface.
