Comparative Study of Biocompatible Titanium Alloys Containing Non-Toxic Elements for Orthopedic Implants

Titanium alloys, particularly Ti6Al4V, are commonly used in biomedical applications. However, the inclusion of aluminum (Al) and vanadium (V) this alloy can cause cytotoxic effects human body, resulting Alzheimer’s disease cancer. This study compares performance biocompatible alloys containing non-toxic elements, such as tin (Sn) niobium (Nb), which considered safe for implantation. Two sets were selected, Ti5Sn Ti5Sn5Nb, their properties compared to Ti6Al4V. First, prepared using a power metallurgical technique. Then, phase analysis, hardness, wear resistance, strength, corrosion simulated body fluid (SBF) solution characterized. Optical microscopy was microstructure, XRD identify phases, electrochemical testing conducted assess alloys’ anodic cathodic characteristics. Nanoindentation techniques analyze surface characteristics, elastic modulus, nano resistance. The results showed Nb Sn had lower rates SBF Al-containing alloys. Moreover, Nb-containing exhibited highest 72% higher than corrosion-resistant those without or Sn, suggesting they may be ideal orthopedic implants humans.
