| 摘 要： | 本文采用化学沉淀法制备了羟基磷灰石(HAP)纳米粉体,利用铁粉和铝粉经过高能机械球磨和热处理工艺制备了金属间化合物Fe3Al粉体;将制备的HAP粉体为基体按质量百分含量加入4;的Fe3Al粉体,经过球磨分散得到复合粉体,然后经过冷压成型和160MPa冷等静压成型及1200℃真空无压烧结,得到羟基磷灰石与金属间化合物Fe3Al的生物复合材料.通过XRD、SEM等测试方法揭示了材料的相组成及微观结构,研究结果表明:采用化学沉淀法制备的羟基磷灰石粉体粒径在100纳米以内,结晶度高、粒度均匀,纯度高;Fe3Al质量含量为4;的Fe3Al/HAP生物复合材料HAP的基本晶体结构没有因为Fe3Al的加入而发生变化,其抗弯强度为89.6MPa,较纯羟基磷灰石陶瓷有了较大的提高,证明Fe3Al增强HAP是有效的.

| Abstract: | In this paper the authors mainly studied the preparation and properties of Fe3Al/HAP bioceramics composite.Ball milling technology are used for the mixing of hydroxyapatite and Fe3Al powder.Firstly,powder mixture are moulded by chill-pressing and isostatic cool pressing,followed in vacuum sintering.The phase and microstructure of bioceramics was studied by XRD and SEM.The bending strength of composite is improved when Fe3Al was added to hydroxyapatite.The study showed the bioceramics had good mechanical properties.The composites were new biomaterials with excellent prospects. |
