采用等离子喷涂技术在Ti6 Al 4V基体上制备了HA-ZrO 2-Ti功能梯度涂层。用X射线衍射仪和扫描电镜结合能谱仪研究了涂层的残余应力和表面形貌。结果表明：（1）FGC涂层的残余应力为72.1Mpa，远低于HA涂层。（2）FGC涂层的表面形貌具有等离子喷涂涂层的特征，由于其梯度涂层与基体的热膨胀相匹配，没有观察到微裂纹。
In the present study, Functionally gradient HA-ZrO2-Ti coatings (FGC) on Ti6Al4V were prepared by the plasma spraying process. The residual stress and surfacial morphology of coating were studied by X-ray diffraction and scanning electron microscopy with an energy dispersive spectroscopy. The results showed that: (1) the residual stress of FGC is 72.1Mpa, much lower than that of single HA coating, (2) The surfacial morphology of the FGC showed typical characteristics of plasma-sprayed coating, no microcracks was observed because of its the thermal expansion matched between the gradient coating and substrate.
