Micro-arc oxidation of Ti6Al4V and Ti6Al7Nb alloys for biomedical applications

Materials Characterization, 2011
Abstract In the present study, the in-vitro biological responses of two competitive titanium alloys (Ti6Al4V and Ti6Al7Nb) were investigated after modifying their surfaces by the micro-arc oxidation (MAO) process conducted in a (CH3COO)2Ca·H2O and Na3PO4 containing electrolyte under identical electrical parameters and exposure time. After the process,
