Abstract Scope |
One of the most attractive biomaterials for use in biomedical applications is Ti-Ni alloy. This work aims to produce a new Ti-Ni alloy with enhanced corrosion resistance and good mechanical properties by using the mechanical alloying (MA) method at different times. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and nanoindentation tests were used to examine the structural and mechanical properties. A three-electrode cell in Hank's solution was used to investigate the electrochemical characteristics of Ti-Ni alloys. To assess the corrosion resistance of the alloys, potentiodynamic polarization, open-circuit potential (OCP), and the electrochemical impedance spectroscopy (EIS) technique were utilized. The findings demonstrated that the Ti-Ni alloy's porosity and particle size reduced as milling times increased. Conversely, the microstrain, relative density, hardness, and Young's modulus increased. The electrochemical results confirmed that the Ti-Ni alloy produced at higher milling times exhibits excellent corrosion resistance, making it useful for bone implants. |
