摘要
分别将钙、磷离子以110 keV、80 keV的能量和2×1017ion/cm2、1×1017ion/cm2的剂量注入纯钛基体,并与水热处理结合制备钛表面羟基磷灰石(HAp)改性层。为研究预氧化在离子注入与水热处理制备羟基磷灰石活性层中的作用,将预氧化试样与未氧化抛光试样一起进行了钙、磷离子注入和水热处理,并利用SEM进行形貌观察,AES、EDS、XRD和FTIR进行元素及物相结构分析。结果表明,经过预氧化处理的试样表面生成了球状HAp改性层。另外,水热处理温度、压强和钙、磷注入顺序也会对HAp的形成产生影响。
Ion implantation and hydrothermal process were performed to prepare hydroxyapatite (HAp) coatings on pure titanium surface. Both pre-oxidized and un-oxidized titanium samples were implanted with dual calcium and phosphorus ions and then hydrothermal treated in order to evaluate the effect of pre-oxidization on the formation of HAp. SEM was used to observe the morphology and AES, XRD and FTIR analyses were performed to identify the surface elements and structure of various titanium samples. The results show that globular HAp coatings form on the surface of pre-oxidized titanium samples during subsequent hydrothermal treatment. In addition, the formation of HAp coatings is also affected by hydrothermal temperature,pressure,and implantation order of calcium and phosphor.
