Effect of Torsion on the Corrosion Resistance of Nanotubular Anodized Spiral Plates for Femoral Fracture Fixation

Year: 2024

Type: article

Abstract: The long-term performance of nanotubular anodized spiral plates used for femoral fracture fixation depends on their corrosion resistance in physiological environments. This study investigates the impact of torsion on the corrosion resistance of these implants. Torsion was found to significantly alter the implant's surface properties, affecting its electrochemical behaviour and corrosion resistance. While torsion increased the corrosion potential and electrochemical activity, it compromised the passive oxide layer, leading to reduced corrosion resistance. Electrochemical impedance spectroscopy (EIS) revealed increased solution resistance and decreased polarization resistance post-torsion. These findings provide important insights for designing more durable biomedical implants.
