چکیده
|
Magnesium alloys are increasingly valued for biomedical applications due to their biocompatibility. this study investigates mg-az31b alloy samples treated with quartz and alumina grits (<200 μm) at varied pressures, followed by anodization in an eco-friendly alkaline electrolyte. the results show that increased blasting pressure produces a rougher surface. anodization time significantly affects the thickness of the anodic film, leading to a transition in surface morphology from fine to coarse structures with complete film coverage. characterization by xrd reveals that the anodic film mainly comprises magnesium oxide and hydroxide phases. open circuit potential (ocp) measurements demonstrate enhanced corrosion resistance post-anodization, particularly notable at 40 minutes on alumina-blasted samples. anova confirms that both blasting pressure and anodization time significantly influence coating thickness and ocp, indicating the formation of a dense anodized layer.
