本研究的目的有两个。首先，提供了一种来源于牛骨的纳米羟基磷灰石（BHA），作为HA的原料和天然来源，并获得烧结BHA陶瓷的力学和摩擦学性能。其次，通过将纳米尺寸的BHA作为骨相容性纳米填料，评价了市售骨水泥的机械和摩擦学性能。为了实现这两个目标，烧结BHA陶瓷和纳米复合水泥的力学和摩擦学性能进行了测试，采用纳米压痕和纳米划痕实验。结果表明，以天然牛骨为原料可以制备出结晶度高、力学性能和摩擦学性能良好的单相纳米羟基磷灰石。此外，它被发现，纳米复合材料与10重量%的BHA表现出良好的机械和摩擦学性能的改善与其他检查PMMA/BHA纳米复合材料相比。(C)2015 Elsevier Ltd和Techna Group S.r.l.

The aim of this study is twofold. Firstly, it provides a nano-sized hydroxyapatite derived from bovine bone (BHA), as a raw material and natural source of HA, and to obtain the mechanical and tribological properties of sintered BHA ceramic. Secondly, it evaluates the mechanical and tribological properties of a commercially available bone cement by incorporating nano-sized BHA as a bone compatible nano-filler. In order to achieve these two goals, the mechanical and tribological properties of sintered BHA ceramic and nano-composite cements were measured using nano-indentation and nano-scratch experiments. The results indicated that the nano-hydroxyapatite of single phase with high crystallinity and appropriate mechanical and tribological properties could be produced from the natural bovine bone. Moreover, it was found that the nano-composite with 10 wt% BHA exhibited a good improvement in mechanical and tribological properties in comparison with other examined PMMA/BHA nano-composites.
