摘要

In order to address the requirement for better implant integration and decreased bacterial colonization, this study investigates the biocompatibility of multi-bio covered laser-textured Ti- 6 Al- 4 V alloy for orthopedic implants. Surface changes are required for conventional titanium implants due to issues with bacterial adherence, osseointegration, and biocompatibility. Ti- 6 Al- 4 V was electrochemically coated with a multi-bio coating (Chitosan + HA + ZnO + TiO₂) and laser-textured with micro-dimple patterns using a 60 W fiber laser to improve implant performance. Energy Dispersive Spectroscopy, 3D optical profilometry, contact angle measurements, and microscopic cell adhesion evaluations were used to investigate the laser-textured surfaces. The outcomes verified the successful creation of micro-dimples at different distances (100, 150, and 200 µm) and the presence of essential components. Better cell adherence was seen on the textured surface with a 100 µm dimple distance, while microscopy examination showed enhanced biocompatibility in multi-bio coated materials. The sample with the best osseointegration exhibited the strongest cell adhesion (182.6 ± 29.98), the highest coating thickness (46.8 µm), and the highest contact angle (70.826°). According to this study, laser texturing combined with multi-bio coatings significantly improves the biological performance of Ti- 6 Al- 4 V implants, making them a good alternative for orthopedic applications.
