Improvements of mechanical and anticorrosive properties, as well as superior osseointegration of the hydroxyapatite coated titanium alloy were reported in the last years by the addition of different elements (Si or Ti) into hydroxyapatite structure. The aim of this work was to prepare and to investigate the hydroxyapatite (HAP) coatings enriched with SiC in order to enhance the mechanical properties of HAP films. The coatings were deposited on Ti6Al4V alloy substrates by co-sputtering of HAP and SiC targets, using a magnetron sputtering system. The films were characterized in terms of elemental and phase composition, chemical binding, morphology and mechanical properties by EDS, XRD, FTIR, SEM, AFM, and nanoindentation. Overall, improved mechanical properties were found by adding SiC to the basic HAP structure.
近年来，通过向羟基磷灰石结构中添加不同元素（硅或钛），羟基磷灰石涂层钛合金的机械性能和抗腐蚀性能得到了改善，并且其骨整合性也更优异。本研究的目的是制备并研究富含碳化硅的羟基磷灰石（HAP）涂层，以提高HAP薄膜的机械性能。采用磁控溅射系统，通过共溅射HAP靶材和碳化硅靶材，将涂层沉积在Ti6Al4V合金基体上。利用能谱仪（EDS）、X射线衍射仪（XRD）、傅里叶变换红外光谱仪（FTIR）、扫描电子显微镜（SEM）、原子力显微镜（AFM）和纳米压痕技术，对薄膜的元素和相组成、化学结合、形貌及机械性能进行了表征。总体而言，在基本的HAP结构中添加碳化硅后，机械性能得到了改善。
