| Abstract Scope |
Ti-Ni alloy is one of the most appealing biomaterials used in biomedical applications. The objective of this research is to create a novel Ti-Ni alloy with improved corrosion resistance using mechanical alloying (MA) at various times. The phases' compositions, microstructure, and hardness were investigated using XRD, SEM/EDS, and Vickers microhardness analyses, respectively. Furthermore, the electrochemical properties of Ti-Ni alloys were studied using a three-electrode cell in Hank's solution. Open-circuit potential (OCP), potentiodynamic polarization, and the electrochemical impedance spectroscopy (EIS) technique were employed to evaluate the corrosion resistance of the studied Ti-Ni alloys. The results showed that; the particle size and porosity of the binary Ti-Ni alloy decreased with increased milling times. Whereas, the microstrain, relative density, hardness, and Young’s modulus were increased as the grinding time increased. The electrochemical results confirmed that the material produced at higher milling time exhibited excellent corrosion resistance which makes them useful for bone implants. |
