Abstract

Titanium and its alloys are widely used as bone implants due to their superb properties, such as very good biocompatibility, excellent corrosion resistance and a relatively low elastic modulus. However, bonding between a bone tissue and an implant occurs via titanium oxide created on the surface of Ti, which is a long-lasting process. Therefore, creating an implantable surface with a porous TiO2 layer directly on the Ti substrate seems to be a good solution. Moreover, nanostructured titanium oxide layers may be also used as reservoirs ...
