Mechanical and chemical characterization of biomaterials
Abstract
The properties of titan-aluminum materials for medical implantation are analysed. With the help different fatigue testing equipment high-cycle endurance tests are performed. This is done with regard to breaking strength and surface resistance, the latter of which is of interest with respect to long-time bio-compatibility of prosthetic implants (e.g. teeth, hips). Special interest is put into the electrochemical behaviour of metal-metal systems, e.g. the combination of a titan-aluminium stem with a chrome-cobalt joint in prosthetic hips. Aim of the project is the development of techniques to produce Titan prosthetic implants with optimised bio-compatibility and lifetime. In particular, the corrosion behaviour and and debris resistance with respect to different surface treatment is investigated.
