Abstract

This work investigates the development of polymer-based bio-composite-coated layers on a Ti-6Al-4V substrate via electrostatic spray deposition. The coatings were created using varying compositions, including (Pure PLA, 3, 6, and 9) wt.% of silver(Ag) combined with (100,97, 94, and 91) wt.% of PLA powder. Additionally, similar percentages of zirconium oxide (ZrO2) were mixed with (3 and 6) wt.% of silver powder(97 and 94)wt.% of Polylactic acid (PLA) powder. The surface morphology of the coated layers was analyzed using FTIR and SEM/EDS techniques, ion-releasethese show the release of Ti, Al, and V ions decreased, representing a significant enhancement in the alloy's corrosion resistance because of Ti6Al4V alloy is protected from environment and biological factors by the coating layers, antibacterial test demonstrated that the coating layer was effectively uniform and free of cracks. The assessment of scratch hardness was taken to calculate the coating's adherence. The samples exhibited a protective layer, suggesting the establishment of a healthy, durable bond between the surrounding bone tissues and the implant surface, and favorable wetting properties especially, coatings containing Ag (9 wt.%) with an absorption rate of around 62.836% and ZrO2/Ag (3:6wt.%) with an absorption rate of approximately 55.719% proved superior absorption in comparing with the coatings made with pure PLA (74.049%), also inhibited bacterial growth.
