Development of High-Flexural-Strength Titanium/Hydroxyapatite Biocomposites via Cold Spray Deposition with Titanium and Niobium Bond Coats

Achieving rapid, scalable fabrication of bone implants with a high flexural strength remains a major challenge. The persistent issues are mainly attributed to the incompatibility of the biomaterials (e.g., titanium (Ti) and niobium (Nb)) with the processing methods. The implants fabricated from solu...
