纯钛表面仿生矿化性能优化的研究

Study of Optimizing the Biomimetic Minerialization Properties on Pure Titanium Surface

采用不同的碱液处理浓度和处理时间在80℃下处理纯钛的表面并在模拟体液(SBF)中进行仿生矿化。结果表明随着碱液处理浓度和处理时间的增加,纯钛表面在模拟体液中仿生矿化的能力增强。碱液处理的浓度是影响纯钛表面仿生矿化能力的主要因素。经10M/L的碱液处理48h后,纯钛表面生成的是具有(002)和(004)晶体取向的类骨磷灰石(HCA),HCA晶粒生长较大,相互连接形成空间紧凑的结构。

Pure titanium surfaces were treated by alkali solution with different contents and time at 80℃ and subsequently exposed to simulated body fluid for biomimetic minerialization, Increasing the content and time of alkali treatment increased the ability of biomimetic minerialization on pure titanium surfaces, The content of the alkali treatment is the main factor that affects the ability of biomimetic minerialization on pure titanium surfaces. Preferential orientations bone-like apatite （HCA） along the （002） and （004） plane were formed on the pure titanium surface after 10M/L alkali treatment in 48h, The HCA crystalline particles, which are large scales and interconnection, formed the spacial compact structure.
