Development of functionally grated biomaterial by Spark Plasma Sintering and application to crown restoration

采用放电等离子烧结法制备了钛瓷功能梯度材料，并对其力学性能进行了测试。制备了分级分级的功能梯度材料，并通过径向拉伸试验测试了其力学性能。结果表明，按生产说明书烧制的瓷器，其价值约为瓷器的两倍。超过一半的试件在瓷器部分出现部分断裂，其他的不能识别瓷器的剥离。从这些结果来看，功能梯度材料的力学性能的改善是通过其组成的梯度来实现的。

Ti-porcelain functionally graded material(FGM) was produced by Spark Plasma Sintering and examined its mechanical property. FGM which consists of graded in stages was produced and its mechanical property was measured by diametral tensile test. The result showed value about two times higher than that of porcelain by firing according to manufacture instruction. And, more than half of the test specimens showed the partial fracture at the part of porcelain, and others were not recognized delamination of the porcelain. From these results, improvement of mechanical property of FGM was recognized by its compositionally graded.
