Corrosion of additively manufactured Ti alloys

点击翻译按钮获取中文摘要

project will look into corrosion of additively manufactured titanium alloys for biomedical applications. This is in collaboration with Oxmet Technologies, and will investigate the corrosion mechanisms caused by body fluids on additively manufactured (AM) Ti-6Al-4V and other alloys used in orthopaedic implants. Additive manufacturing of implant materials offers unique opportunities such as manipulation of AM lattices to maximise bone regrowth and porosity control for stiffness matching between bone and implant material. A combination of modelling and experiments will be performed throughout the duration of this project. Modelling will focus on finite element analysis and the effect of different AM lattices and parameters on the extent of corrosion. Experiments will be conducted to verify these models. Corrosion wear, corrosion fatigue and in-situ corrosion experiments using simulated body fluid solutions will be conducted to better understand the degradation mechanisms of these implant materials.
