This study investigates the biomechanical behavior and corrosion resistance of Ti6Al4V screws coated with hexagonal boron nitride (hBN) and hydroxyapatite (HA) for femoral neck fracture fixation using a triangular configuration under axial loading. Utilizing 3D modeling software (Geomagic Studio and SolidWorks) and numerical analysis with AnsysWorkbench, the screws were designed and analyzed. The study aimed to determine the biomechanical effects and corrosion relationships of Ti6Al4V coated with hBN and HA. Comparative analysis revealed that Ti6Al4V-HA exhibited higher gap (0.036427), penetration (0.0028631), and sliding distance values (0.0024398) compared to Ti6Al4V-hBN (gap: 0.036196, penetration: 0.0028579, sliding distance: 0.0024300), indicating greater reactivity and corrosion potential. Conversely, Ti6Al4V-hBN demonstrated superior corrosion resistance. The findings suggest that hBN-coated Ti6Al4V screws provide improved stability and reduced stress concentration, which are critical for successful fracture fixation. Additionally, hBN coating effectively reduced the corrosion rate of Ti6Al4V in simulated body fluids, enhancing implant longevity and patient safety. However, further in vivo studies are necessary to validate these findings and assess long-term performance and biocompatibility. The study underscores the need to consider multiple factors in implant material selection to gain a comprehensive understanding of corrosion behavior. Overall, this research lays the groundwork for future advancements in orthopedic implant technology and has the potential to improve patient outcomes in fracture management.
