摘要: 采用复合电沉积和电泳沉积两步法在钛基体上制备了Co-YSZ/HAp纳米复合涂层, 与只采用电泳沉积法在钛基体上制备纳米HAp单一涂层进行了比较研究.采用场发射扫描电镜、X 射线衍射和能量散射谱对复合涂层的微观形貌, 纳米HAp外层表面形貌, 晶相, 复合涂层的断面形貌及元素组成分布进行分析研究. 通过粘结-拉伸实验测定了涂层与基体的结合强度, 结果表明, Co-YSZ/HAp 纳米复合涂层与钛基体的结合强度明显高于纳米HAp 单一涂层与钛基体的结合强度, 说明复合涂层具有更好的力学性能.

Abstract: Co-YSZ/HAp nano-composite coating and nano-HAp single coating were deposited on Ti substrate using the combination of electrocodeposition and electrophoretic deposition, and electrophoretic depositions, respectively.Surface and cross section morphologies of the coatings were observed by scanning electron microscope. Element distribution and crystal phase of the coatings were analyzed by energy dispersive spectrum and X-ray diffraction. The adhesive strength of the coating and Ti substrate was determined by shear strength testing. The results indicate that the adhesive strength of Co-YSZ/HAp nano-composite coating and Ti substrate is higher than that of nano-HAp single coating and Ti substrate. It shows that Co-YSZ as an interlayer reduces the mismatch of the thermal expansion coefficients between HAp and titaniumand Co-YSZ/HAp nano-composite coating has better mechanical properties.
