摘　　要：采用Ａｒ＋离子束溅射沉积技术在钛基体上沉积羟基磷灰石薄膜涂层，Ａｒ＋离子束的能量分别为０．９ｋｅＶ、１．２ｋｅＶ和１．５ｋｅＶ。利用Ｘ射线衍射（ＸＲＤ）、扫描电镜（ＳＥＭ）、透射电镜（ＴＥＭ）和红外光谱（ＦＴＩＲ）等检测方法，对制备的羟基磷灰石薄膜涂层进行了表征。Ｘ射线衍射和透射电镜结果表明该薄膜涂层为非晶态；红外光谱中无羟基（ＯＨ－）特征峰存在，ＣＯ＝３根吸收峰的出现说明制备过程中会引入ＣＯ＝３根；扫描电镜观察结果显示出制备的羟基磷灰石薄膜涂层致密、均匀；划痕实验结果表明涂层与钛基体间的结合紧密。以上结果表明，离子束溅射沉积技术可以用于沉积羟基磷灰石薄膜涂层钛种植材料。Ar+ ion beam sputter deposition was used to produce thin hydroxyapatite (HA) coating on polished titanium substrate.In this study,the HA ceramic target was sputtered by an argon-ion beam with an energy of 0.9keV,1.2keV and 1.5keV,respectively.X-ray diffraction (XRD),scanning electron microscopy (SEM),transmission electron microscopy (TEM),and Fourier transform infrared (FTIR) spectroscopy were used to characterize the as-sputtered coatings.XRD analysis and TEM observation revealed that the as-sputtered coating was amorphous.No distinct hydroxyl band was observed in the typical FTIR transmission spectra,and new absorption bands were determined for CO3,which was brought about during the deposition process.SEM observation results indicated that the as-sputtered coatings were uniform and dense.Preliminary scratch measurements suggested a strongly bonded HA coating on the titanium substrate.It was concluded form this study that ion beam deposition technique could be used to produce thin calcium phosphat
