Ti3SiC2 artificial bone material and preparation method thereof
The invention relates to a Ti3SiC2 artificial bone material and a preparation method thereof, and the preparation method comprises the following steps: pressing mixed powder of Ti3SiC2 powder and a pore-forming agent under a set pressure to obtain a green body with a set shape; wherein the set pressure ranges from 500 MPa to 700 MPa, and the pressing treatment time ranges from 1 min to 5 min; performing pore-forming treatment on the green body, removing the pore-forming agent, and cooling to obtain a green body subjected to pore-forming treatment; and under the inert atmosphere condition, carrying out high-temperature sintering treatment on the blank subjected to pore-forming treatment, and cooling to obtain the Ti3SiC2 artificial bone material. The Ti3SiC2 artificial bone material disclosed by the invention not only can meet the load-bearing requirement, but also is endowed with excellent mechanical properties, good in-vitro mineralization ability and biocompatibility, so that the bone regeneration performance is improved, and a safe and effective treatment choice is provided for bone defect repair. The Ti3SiC2 artificial bone material disclosed by the invention can be used for bone defect repair of bearing or low-bearing parts.
本发明是关于一种Ti3SiC2人工骨材料及其制备方法，其中，所述制备方法包括如下步骤：在设定压力下，对Ti3SiC2粉体与造孔剂的混合粉末进行压制处理，得到设定形状的生坯；其中，设定压力为500～700MPa，压制处理的时间为1～5min；对生坯进行造孔处理，脱除造孔剂，冷却后得到造孔处理后的坯体；在惰性气氛条件下，对造孔处理后的坯体进行高温烧结处理，冷却后得到Ti3SiC2人工骨材料。本发明的Ti3SiC2人工骨材料，不仅能满足承重需求，还赋予优异的力学性能，良好的体外矿化能力及生物相容性，从而提高骨再生性能，为骨缺损修复提供了安全、有效的治疗选择。本发明的这种Ti3SiC2人工骨材料可用于承重或低承重部位的骨缺损修复。
