Abstract

Magnesium (Mg) alloys have garnered considerable interest as biodegradable materials for bone fixation implants. In this study, AZ31B Mg alloy substrates were grit-blasted with quartz and alumina particles at varying pressures and subsequently coated with hydroxyapatite via electrodeposition for different durations. Scanning electron microscopy was employed to examine the surface morphology of the hydroxyapatite layer, while potentiodynamic polarization and electrochemical impedance spectroscopy were conducted to assess the layer's nature, coverage, and effectiveness in a simulated body fluid. The findings indicate that longer deposition times led to increased surface coverage. Notably, a capacitive hydroxyapatite layer with a dense inner structure and complete surface coverage was achieved after 40 minutes of deposition on quartz- and alumina-blasted samples at a blasting pressure of 1000 kPa. The findings of this study aid in developing biocompatible coatings on magnesium alloys for bone fixation implants.
