Resumen:
Anodizing is one alternative, but many of the protocols used included hazardous compounds (e.g. chromates or fluorides) or high current densities. In the present study AZ91D Mg alloy was anodized with an environmentally-friendly low cost process, with the aim of controlling hydrogen evolution generating a potential material for orthopaedic devices. Surface was studied by Raman Spectroscopy, SEM, and roughness was assessed using a profilometer.Electrochemical tests (polarization curves and EIS) were conducted in simulated body fluid at 37° C. The influence of the anodizing on the cellular adhesion and viability was assessed using primary culture bovine embryonic fibroblasts (BEFs) and the pre-osteoblastic cell line MC3T3-E1, respectively. Anodized samples showed low hydrogen evolution and improvement of cell adhesion and viability.
