Abstract
Surface of an implant plays a key role in determining the performance as several events are associated with the surface. Modifying the surface with a bioactive coating or/and mechanical treatment can profoundly affect the success of the implant.
Highlights
Biomedical implants are used clinically to replace, support, or enhance non-functional tissues and organs owing to disease, trauma, or congenital defects
2.1 Fe-based Degradable Alloys Owing to its superior mechanical properties, such as high strength and high ductility, Fe-based biodegradable metal alloys have been studied as potential degradable implants such as stents in earlier times 32
Similar results were reported for ZK60 Mg alloys with a 50% increase in corrosion resistance when modified by laser shock peening (LSP) compared to the untreated sample 234
Summary
Biomedical implants are used clinically to replace, support, or enhance non-functional tissues and organs owing to disease, trauma, or congenital defects. Vanadia coating deposited on Mg alloy was prepared by dip-coating and micro-arc oxidation to improve the corrosion and wear resistance All these observations from several studies demonstrate the potential of vanadia as a surface coating material for implants to improve the corrosion resistance and antibacterial property toward minimizing implant-associated infections and facilitate healing by controlling the release of hydrogen gas in the process of corrosion. Numerous studies have reported using iron oxide particle's magnetic hypothermia to eradicate bacterial infection 112, 113 These various properties of iron oxide can be utilized to develop drug/biomolecule eluting coatings on degradable implant surfaces to enhance the bioactivity of the materials. Two or more deposition strategies are being used in more recent times, mainly for Mg and its alloys
