Abstract Scope |
Despite the numerous advantages of magnesium and its alloys, their rapid degradation rate in physiological environments limits their utilization in diverse biomedical applications, such as bone implants. The goal of this study is to study some of the most promising coatings and provide a comparative assessment of their corrosion, morphological, and biological properties. The coatings in this study were created on the surface of a ZK60 magnesium alloy using the plasma electrolyte oxidation (PEO), sol-gel, and polymer dip coating processes. The PEO/Sol-gel composite coating demonstrated the highest in-vitro corrosion resistance, surpassing the other coating groups. The addition of GO layered particles to the PEO coating electrolyte improved corrosion resistance and biocompatibility. The PEO/PCL composite coating exhibited the greatest biocompatibility, evidenced by the highest cell viability and a hydrophilic surface. This study underscores the feasibility of producing biocompatible Mg-based implants with controlled corrosion properties through the application of diverse composite coatings. |
