| description | Biomedical applications, such as artificial implants, are very significant for the disabled due to their usage in orthopedics. Nevertheless, available materials in such applications have insufficient mechanical and tribological properties. The current study investigated the mechanical and tribological properties of a biomedical metallic material, magnesium (Mg), after incorporating titanium dioxide nanofibers (TiO<sub>2</sub>) with different loading fractions. The TiO<sub>2</sub> nanofibers were synthesized using the electrospinning technique. The ball-milling technique was utilized to ensure the homogenous distribution of TiO<sub>2</sub> nanofibers inside the Mg matrix. Then, samples of the mixed powder with different loading fractions of TiO<sub>2</sub> nanofibers, 0, 1, 3, 5, and 10 wt.%, were fabricated using a high-frequency induction heat sintering technique. The physicomechanical and tribological properties of the produced Mg/TiO<sub>2</sub> nanocomposites were evaluated experimentally. Results showed an enhancement in mechanical properties and wear resistance accompanied by an increase in the weight fraction of TiO<sub>2</sub> nanofibers up to 5%. A finite element model was built to assess the load-carrying capacity of the Mg/TiO<sub>2</sub> composite to estimate different contact stresses during the frictional process. The finite element results showed an agreement with the experimental results. |
