Effect of oxidation heat treatment on the microstructure, corrosion, adhesion, and biocompatibility of a biomedical TiZrNb medium-entropy alloy

Key Points

• Corrosion resistance was significantly improved after oxidation heat treatment, suggesting better longevity in biomedical use.
• Biocompatibility tests indicate that the treated TiZrNb alloy has enhanced compatibility with biological environments, ensuring safer applications.
• Heat treatment modified the microstructure of the medium-entropy alloy, potentially influencing its mechanical properties and performance.
• Adhesion strength was notably higher post-treatment, emphasizing the importance of oxidation in material preparation for biomedical devices.
