评估了钛等离子喷涂（TPS）和氧化锆（ZrO2）涂层钛（Ti）基材对等离子喷涂羟基磷灰石（HA）涂层的粘合性、成分和结构性能的影响。使用 X 射线衍射、傅里叶变换红外 (FTIR) 光谱、扫描电子显微镜、能量色散光谱、表面粗糙度和粘合强度来表征涂层。所有 HA 涂层均观察到磷灰石型和 α-磷酸三钙相。在 FTIR 分析过程中，所有 HA 涂层均观察到由于缺乏 960 cm−1 峰而导致的结构变化。涂层表面显得粗糙且熔化，表面粗糙度与起始粉末的尺寸相关。没有观察到 Ti 和 TPS 涂层 Ti 基材上 HA 的 Ca/P 比存在显着差异。然而，ZrO2 涂覆的 Ti 基底上 HA 的 Ca/P 比显着增加。除 TPS 涂层钛基材界面上的 HA 涂层外，所有涂层和基材之间的界面均观察到致密且紧密结合。然而，与 Ti 基材上的 HA 相比，HA 和 Ti 基材之间的中间 TPS 或 ZrO2 层导致粘合强度较低。 © 2003 Wiley periodicals, Inc.

The effect of titanium plasma‐sprayed (TPS) and zirconia (ZrO2)‐coated titanium (Ti) substrates on the adhesive, compositional, and structural properties of plasma‐sprayed hydroxyapatite (HA) coatings were evaluated. X‐ray diffraction, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy, energy dispersive spectroscopy, surface roughness, and adhesive strength were used to characterize the coatings. Apatite‐type and α‐tricalcium phosphate phases were observed for all HA coatings. A structural change due to the absence of a 960 cm−1peak during FTIR analysis was observed for all HA coatings. The coating surfaces appeared rough and melted, with surface roughness correlating to the size of the starting powder. No significant difference in the Ca/P ratio of HA on Ti and TPS‐coated Ti substrates was observed. However, the Ca/P ratio of HA on ZrO2‐coated Ti substrate was significantly increased. Interfaces between all coatings and substrates were observed to be dense and tightly bound, except for HA coatings on TPS‐coated Ti substrate interface. However, an intermediate TPS or ZrO2layer between the HA and Ti substrate resulted in a lower adhesive strength as compared to HA on Ti substrate. © 2003 Wiley Periodicals, Inc.
