Abstract

Magnesium (Mg) alloys as biodegradable materials, are attracting significant importance for implant applications due to their suitability as biodegradable material. In the present research, An AZ31B Magnesium alloy was grit blasted with quartz and alumina particles with different blasting pressures and anodized in KOH solution for different durations to develop an anodized film on the different substrates. The surface morphology of the anodization layer was analyzed by scanning electron microscopy. The nature, coverage, and effectiveness of the anodized layer were investigated with potentiodynamic polarization (PD) scans and electrochemical impedance spectroscopy (EIS) in a simulated body fluid (SBF) solution. The results show an increase in surface coverage with an increase in anodization time. It is also revealed that a capacitive anodized layer with a dense inner layer having full coverage was obtained at 40 minutes anodization time for quartz and alumina blasted samples at 1000 kPa blasting pressure. The outcomes of this study help in developing a protective anodized film on the surface of Mg alloys for bone fixation implants.
