Notes:
A comparative study was presented to demonstrate the clear influence of the different bufferlayer (TiN and TiO2) on the HA film. In this study, magnetron sputtering was applied for differentfilm deposition. Nano-indentation was used to examine the mechanical properties of the HA film onboth TiN and TiO2 buffer layers. It is found that HA film on TiN buffer layer is harder and the HAfilm on TiO2 buffers is more rigid. Further more, the simulated body fluid (SBF) soaking test wasselected to investigate the properties of the HA/TiN and HA/TiO2 films in the physiological media.The obvious delamination was observed on the surface of HA film on TiN buffer layer, while thesurface morphology of HA film on TiO2 buffer layer remained nearly unchanged. The resultindicated that TiO2 buffer layer shows a better interfacial bonding to the HA film
