The aim of this paper is to report the use of the anodic bonding technique to bond titanium alloy and two different bioactive glasses aiming the medical application of these biomaterials. Ti alloy and bioactive glasses 52S4.6 and 45S5 were successfully bonded using anodic bonding technique for range of temperature and applied potential. The effects of anodic bonding parameters over the total charge transferred and the bonding time were evaluated. The adhesion of Ti alloy and bioactive glasses was measured by shear test. Due to polishing process, titanium alloy samples shown a slightly rounding and consequently the bonding area was limited to part of the sample area. It was found the temperature and potential have effect with statistical significance over the total transferred charge and the bonding time. The results herein discussed suggest the viability of anodic bonding added to process versatility and material compatibility for the use of bioglass and Ti alloy bonded together on medical application.
