| Abstract Scope |
Biomedical high-entropy alloys (Bio-HEAs) have gained attention for the manufacture of biomedical implants due to their unique combination of crystalline structures, low elastic modulus, and superior mechanical strength. However, the surface of metallic biomaterials still needs to be improved to become more friendly for the biological environment and cell growth. In this context, this study aimed to functionalize the surface of a novel Bio-HEA by micro-arc oxidation (MAO). The ingots were produced by arc melting and then subjected to MAO treatment at 300 V and 2.5 A, for 1 to 9 minutes, in a Ca-, P-, and Mg-rich electrolyte. The treated samples exhibited a porous surface with micrometer-scale thickness and were enriched with both alloying and electrolyte elements. These features, along with a hydrophilic surface and enhanced corrosion resistance, indicate promising characteristics for potential use in biomedical applications.
