  • Electrochemical analysis in simulated body fluid (SBF).
  • Corrosive wear testing using pin-on-disk geometry against zirconia in SBF.
  • Osteoblast cell culture studies to evaluate cell adhesion, viability, and proliferation.

    • Main Results:

    • Laser nitriding significantly enhanced osseointegration, corrosion resistance, and tribological properties of Ti-6Al-4V.
    • Electrochemical analysis confirmed improved corrosion resistance in SBF.
    • Corrosive wear tests demonstrated superior performance of the nitrided surface.
    • Osteoblast cells exhibited high viability and adhesion; proliferation was observed at specific laser energy densities (1.89 and 2.12 × 10^6 J/m^2), while lower energy (1.70 × 10^6 J/m^2) inhibited it.

    Conclusions:

    • Laser nitriding is an effective surface treatment for improving the biomedical performance of Ti-6Al-4V implants.
    • The enhanced properties suggest improved implant integration and durability in vivo.
    • Optimized laser nitriding parameters are critical for promoting favorable cellular responses and proliferation.
