| Abstract Scope |
Cost-effective Ti-6Al-4V biomaterial powder with non-spherical morphology is produced by Hydride-Dehydride (HDH) method and processed by laser powder bed fusion (L-PBF) for biomedical implant purposes. It is generally recognized that corrosion behavior is negatively affected by heterogeneous microstructure and defects. Thus, it is needed to conduct a systematic study on the role of processing parameters and post processing heat treatments on microstructure, which can enhance our understanding on possible defect formation in micro and macro scale and their impact on corrosion resistance. Thus, corrosion behavior is investigated in different electrolytes (e.g., dulbecco's modified eagle medium (DMEM) and phosphate buffered saline (PBS)), coupled with optical and scanning electron microscopy observations to understand role of the material’s microstructure and phase formation (such as α, α’, β) on dissolution of alloying elements in contact with cells and physiological solutions present in tissues. Results indicate potential application of non-spherical material for fabrication of bio-implants. |
