熔盐电解清洁冶金制备含高熔点金属组分植入材料的相关研究

With the mankind entered the aging is accelerating, unpredictable large disasters( such as the Wenchuan earthquake )happened by accident, which increasing demand for medical implant materials. But in all materials, metal materials in the clinical application of the earliest is also the most widely used. Wherein the titanium alloy material (Ta,Nb,Zr) has a high melting point, high density, good workability, corrosion resistance, weldability and low plastic / brittle transition temperature and excellent performance has been widely used in biomedical metallic implant materials. In many preparation methods, although the FFC method as well as the derivative of CAC ( computer aided control ) method has made some achievements in the progress of clean metallurgy industrialization, however, to find a more suitable and broad is a common goal for the development direction of this field researchers. In this application, the team plans to apply this method in the preparation of a series of titanium ( Ta, Nb, Zr ) of alloy matrix biomedical materials. This project is based on the previous research results through the prepared products under different conditions which was analyzed and the mechanism of the reaction of reduction process, and continue to compared and summarized on the reaction energy consumption, current efficiency and material properties, so as to optimize the reaction conditions.

随着人类进入高龄化的步伐不断加快、大型不可预知的灾难的发生（如汶川地震）等，使得医用植入材料的需求不断增加。而在所有材料中，金属材料在临床上应用得最早同时也是最广泛的。其中钛（钽、铌、锆）合金材料具有熔点高、密度高、良好的可加工性、耐腐蚀性、可焊性以及低的塑/脆转化温度等优良的性能被广泛应用于医用金属植入材料中。在众多制备方法中，虽然FFC方法以及衍生而来的CAC（计算机辅助控制）法在清洁冶金工业化进展上取得了一定的成就，然而寻找更合适和广阔的发展方向是本领域研究者们共同的目标。在此，申请人团队计划将该方法应用于制备上述一系列钛（钽、铌、锆）基生物医用材料合金的研究。本项目旨在根据前一阶段研究成果的基础上通过对不同条件下制备的产物进行分析并探究该反应还原过程的机理，并对反应能耗和电流效率以及产品材料各种性能进行对比和总结，从而对反应条件进行优化。

随着人类社会进入高龄化步伐的加快以及不可知灾难的发生，人体金属植入材料的发展显得越来越重要。人体关节作为一种植入材料必须要满足以下几个条件：生物相容性、生物力学相容性和生物结合性。本项目将已有熔盐电解固态混合氧化物制备合金的方法应用于制备人工植入材料系列的研究，特别是目前热门的钛基合金的制备，首先通过恒槽压电解制备了一系列不同的产物并分析探讨了其材料成型的机理。将筛选的产物进行后处理以后，通过生物分析、材料分析等手段研究了所制备产物的性能，并根据结果对FFC在此领域的发展以及存在的问题进行了研究和探讨。
