Corrosion of additively manufactured Ti alloys

该项目将研究生物医学应用中添加制造的钛合金的腐蚀。这是与Oxmet Technologies合作开展的，将研究体液对添加制造的(AM)Ti-6Al-4V和其他用于骨科植入物的合金造成的腐蚀机制。种植体材料的添加制造提供了独特的机会，例如操纵AM晶格以最大限度地促进骨再生，并控制孔隙率以实现骨与种植材料之间的硬度匹配。在整个项目期间，将进行建模和实验相结合的工作。建模将侧重于有限元分析以及不同AM格子和参数对腐蚀程度的影响。将进行实验来验证这些模型。将使用模拟体液溶液进行腐蚀磨损、腐蚀疲劳和现场腐蚀实验，以更好地了解这些植入材料的降解机制。

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.
