Abstract Scope |
The 3D-printed beta-Ti alloy (Ti-1553) exhibits exceptional mechanical strength and superior corrosion resistance, particularly in biocompatible applications. However, concerns arise regarding the alloy's tendency to release metal ions and debris over time, especially due to corrosion, which poses potential toxicity risks to health. To address this, the present research focuses on refining the corrosion resistance properties under wet conditions by meticulously adjusting the process parameters in the Laser Powder Bed Fusion (LPBF) process, such as build orientations. By altering the printing orientations (0, 35, 45 and 90 Degrees), a set of components of such alloys are efficiently fabricated. A comprehensive testing is carried out in a sodium chloride-based electrolytic solution to assess corrosion behaviours, alongside the investigation of metallic ion emission under diverse conditions and subsequent microstructural changes. This study aims to advance the biocompatibility and performance of printed beta-Ti alloys in extreme wet conditions. |
