| Abstract Scope |
Implant-associated infections often require revision surgery, which is more complex and risky than the initial procedure. Recent advances in antibacterial coatings aim to prevent bacterial colonisation on medical implants. Our study investigates the use of molybdenum (Mo), a promising biocompatible and biodegradable material, in combination with silver (Ag) to combat bacterial infection. Using physical vapour deposition, we have systematically investigated a wide compositional range with a gradient of approximately 40 at% of each element. The study includes high-throughput characterisation of Mo-Ag alloys to assess phase composition, mechanical properties, corrosion behaviour and antibacterial efficacy. Electrochemical tests revealed the presence of microgalvanic couplings in the Mo-Ag film, which enhance the release of Mo ions. The synergy between biologically advantageous Mo and controlled Ag ion release indicates significant potential for biomedical applications of sputter-deposited Mo-Ag films. Our findings highlight regions with effective antibacterial properties and high hardness, essential for implant coating durability. |
