| Abstract Scope |
Metallic implants are essential in medicine, targeting bone regeneration, reducing corrosion, controlling ion release, and preventing infections. The rise in antibiotic resistance calls for new antimicrobial coatings. This research examines the effects of PEO + PCL hybrid coatings on titanium to boost its resistance to wear and corrosion while adding antibacterial properties. Titanium (TiGr2) underwent plasma electrolytic oxidation (PEO), followed by applying a bioabsorbable polymer (PCL) layer containing Vancomycin. The coatings were analyzed using SEM/EDS, XRD, and wettability tests. Tribocorrosion assessments were conducted in artificial saliva with a ball-on-plane sliding mechanism, linked to a potentiostat. Additionally, the coatings' antibacterial efficacy was evaluated. Results showed that PEO+PCL+Vanco coatings significantly enhanced tribocorrosion resistance and effectively combated S. aureus and P. aeruginosa. This improvement in both durability and antibacterial performance suggests these coatings could lead to advanced implant surfaces, offering better clinical outcomes. |
