Electrochemical and bioactive characteristics of the porous surface formed on Ti-xNb alloys via plasma electrolytic oxidation

This study examined the capability of plasma electrolytic oxidation (PEO) to fabricate an ideal implant porous material for bio-implant applications. For this purpose, the Ti-xNb binary alloys (x = 10, 30, and 50 wt.%) were treated via PEO using a DC power supply at a voltage was fixed to be 280 V for 180 s using an electrolyte composed of calcium acetate and calcium glycerophosphate. The structure of Ti-xNb alloys before PEO was altered from...
