Abstract—

In order to better integrate 316 L stainless steel implants, in this study, hydroxyapatite/chitosan (HA/CS) nanocomposite coatings, barium titanate/chitosan (BT/CS), and hydroxyapatite/barium titanate/chitosan (HA/BT/CS) were applied on the mentioned steel via electrophoretic deposition at 10 V for 150 s. Tri-ethanolamine was used as a dispersant to create a stable suspension. The microstructure, the chemical composition, and the phase structure of materials and coatings were investigated by scanning electron microscopy, energy dispersive X-ray, X-ray diffraction, and Fourier transform infrared spectroscopy. In order to investigate the role of BT in the hardness of the coatings, the obtained hardness of each was compared with each other. To investigate the changes made before and after exposure to the simulated body fluid, the topography and roughness of the surface coatings created were investigated by the atomic force microscopy. The corrosion resistance of the coatings was evaluated by the Auto lab machine and in the simulated body fluid. The results of this study showed that increasing the amount of BT on the HA/CS coating increases hardness and the corrosion resistance of coatings in a simulated body fluid.

316L不锈钢上电泳沉积羟基磷灰石/钛酸钡/壳聚糖纳米复合涂层的腐蚀性能研究

摘要—

为了更好地整合316 L不锈钢植入物，本研究使用了羟基磷灰石/壳聚糖（HA / CS）纳米复合涂层，钛酸钡/壳聚糖（BT / CS）和羟基磷灰石/钛酸钡/壳聚糖（HA / BT / CS）通过10 V的电泳沉积150 s施加于上述钢材上。三乙醇胺用作分散剂以产生稳定的悬浮液。通过扫描电子显微镜，能量色散X射线，X射线衍射和傅里叶变换红外光谱研究了材料和涂层的微观结构，化学成分以及相结构。为了研究BT在涂层硬度中的作用，将每种获得的硬度相互比较。要研究暴露于模拟体液之前和之后的变化，通过原子力显微镜研究所产生的表面涂层的形貌和粗糙度。涂层的耐腐蚀性通过自动实验室机器和模拟体液进行评估。这项研究的结果表明，增加HA / CS涂层上的BT量可以提高模拟体液中涂层的硬度和耐腐蚀性。
