In this study, the corrosion behavior of turmeric-coated AZ51 alloy is studied in a simulated bodily fluid (SBF) and then correlated using different characterization techniques. Optical microstructures of all the samples reveal the presence of grains of the α-Mg alloy and precipitates of β-Mg17Al12. Two well-defined peaks were obtained from the XRD patterns -Mg and Mg17Al12, correlating with the optical microscopy results. The potentiodynamic polarisation investigation illustrates the corrosion behavior of uncoated (UC) and turmeric-coated magnesium samples dipped for 24 (DC-24), 48 (DC-48), and 96 hours (DC-96). Results confirmed that the DC-48 sample shows the maximum corrosion resistance among all the samples, and the EIS study correlates well with the study. The mineralization study confirms that the DC-48 sample has the maximum corrosion resistance due to the uniformity and compact nature of the coating.
