Study demonstrates enhanced mechanical properties and bioactivity of cerium-integrated hydroxyapatite coatings, suggesting their potential in orthopaedic implants.
Key Points
The HAP-CNT-0.8Ce variant showed a maximum hardness of 354 HV and an adhesion strength of 52 MPa, demonstrating superior mechanical properties.
With a Ca/P atomic ratio of 1.56 and reduced bacterial viability of 67.5% for E. coli, the coatings also exhibited noteworthy antibacterial activity.
Sustained ion release in simulated body fluid led to enhanced biomineralization, validating the biofunctionality of these advanced coatings.
Implementing cerium integration within hydroxyapatite coatings presents promising implications for strengthening orthopaedic implants and improving osseointegration.
