In the present study,swine thighbone samples with different water contents were prepared through process of dehydration.The influence of water content on the biotribological behavior of the bone tissue was studied with nanoindentation test,reciprocating sliding test and impact wear test.It is shown that the water contents had significant influence on the mechanical properties and biotribological behavior of the swine thighbone samples.In this experiment condition,with decreasing water content,the hardness and elastic modulus of the swine thighbone samples increased,while the tribological properties significantly decreased.The viscoelasticity of bone tissue decreased with decreasing water content,which mainly resulted in different wear mechanisms of the bone tissue samples under applied loading.
在本研究中，通过脱水处理制备了具有不同含水量的猪大腿骨样本。采用纳米压痕试验、往复滑动试验和冲击磨损试验研究了含水量对骨组织生物摩擦学行为的影响。结果表明，含水量对猪大腿骨样本的力学性能和生物摩擦学行为有显著影响。在本实验条件下，随着含水量的降低，猪大腿骨样本的硬度和弹性模量增加，而摩擦学性能显著降低。骨组织的粘弹性随含水量的降低而降低，这主要导致了骨组织样本在加载下的不同磨损机制。
