Electron Beam Melting with Titanium Alloy for Orthopaedic Applications

点击翻译按钮获取中文摘要

Ti-6Al-4V is a commonly used high specification metal alloy due to its high specific strength, corrosion resistance and good biocompatibility. This combination of properties makes it high in demand in the medical industry for maxillofacial and musculoskeletal implants, where the need to withstand repeated loading is essential for product function.However, the fatigue strength is detrimentally affected by porosity found within products. This project will analyse variables associated with the Electron Beam Melting powder bed additive manufacture process and relate these to porosity. The aim is to establish knowledge on the sources of porosity which can be implemented within a quality system to avoid the creation of porosity, allowing the creation of repeatable properties from batch to batch, establishing a standardised process for high performance functional implants.
