摘要

摘要在本研究中，研究了涂有姜黄的AZ51合金在模拟体液（SBF）中的腐蚀行为，然后使用不同的表征技术进行了关联。所有样品的光学微观结构表明，存在α-Mg合金晶粒和β-Mg17Al12沉淀。从XRD图谱中获得了两个明确的峰——Mg和Mg17Al12，与光学显微镜结果相关。动电位极化研究说明了未涂覆（UC）和涂有姜黄的镁样品浸渍24小时（DC-24）、48小时（DC-48）和96小时（DC-96）的腐蚀行为。结果证实，DC-48样品在所有样品中表现出最大的耐腐蚀性，EIS研究与该研究密切相关。矿化研究证实，由于涂层的均匀性和致密性，DC-48样品具有最大的耐腐蚀性。

Evaluation of corrosion behaviour of turmeric-coated AZ51 alloy in simulated body fluid for biomedical applications

ABSTRACT 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.
