Biomaterials which me used in orthopaedic surgery, introduce the problem of their behaviour in body. When they me metallic it can happen a metal release. Ti6A14V titanium alloy is used for its good mechanical properties and its corrosion resistance. The use of coating makes it possible to improve its performance. I studied two glasses coatings referred BVA and BVH. The characterisation in vivo and in vitro was performed with several techniques of analysis: electronic microscopies and nuclear methods (PIXE, ...). The BVA glass proved to be bioactive. It is transformed into a silicon gel with incorporation of proterns and trace elements (Zn and Sr), after 3 months of implantation. This gel disappears gradually and is replaced by neoformed bon...
