摘要 目的:研制口腔修复用钛锆铌锡(Ti-12.5Zr-3Nb-2.5Sn)合金,并评价合金铸造加工性能。方法:制备Ti-Zr-Nb-Sn合金,采用国产LZ5型离心铸钛机铸造试样,测试合金的铸流率,铸造反应层和线收缩率。结果:400℃时铸造,合金铸流率为100%,铸造线收缩率,表面反应层满足修复支架的铸造要求。结论:Ti-12.5Zr-3Nb-2.5Sn合金具有良好铸造加工性能,可满足口腔修复材料的临床应用要求。 Objective： A new titanium alloy（Ti-12.5Zr-3Nb-2.5Sn） was developed to meet the needs of clinical requirements for medical titanium alloys and casting performance of Ti-12.5Zr-3Nb-2.5Sn alloy.Methods： Samples of a newly developed Ti-Zr-Nb-Sn alloy were prepared.Samples were casted by LZ5-centrifugal casting machine.Casting temperature of the titanium alloy and the casting flow rate were detected.Casting reaction layer and linear shrinkage were evaluated.Results： The casting flow rate was 100% when the alloy were casted at 400℃.Linear shrinkage and the surface reaction layer met the demands.Conclusions： Ti-12.5Zr-3Nb-2.5Sn alloy,as a dental restoration material,was proved to possess favorable mechanical and casting performance properties.
