Abstract

In this study, AZ31B Magnesium alloy samples were grit blasted with quartz and alumina particles at 1000 kPa blasting pressure to achieve sample roughness. The blasted samples were anodized and electrodeposited HA-coated for 40 minutes to improve the corrosion resistance and biocompatibility. The coating characteristics and composition of the coatings were studied by scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analysis respectively. The thickness of the coatings was measured using optical microscope. The corrosion behavior of the coatings was determined by open circuit potential (OCP) in a simulated body fluid (SBF) solution. The biocompatibility of the coatings was analyzed by bio-assessment using MTT assay. The results revealed that the electrodeposition of HA coating on alumina blasted samples results in best surface morphology, yielding lowest corrosion rate and best biocompatibility with a cell viability about 80% even after 7 days treatment.
