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.

采用火花等离子烧结技术制备了钛瓷功能梯度材料（FGM）并测试了其力学性能。制备了分级分级的FGM，并通过径向拉伸试验测定了其力学性能。结果表明，其价值比按照制造说明烧制的瓷器的价值高出约两倍。并且，超过一半的测试样品显示瓷体部分出现局部断裂，而其他样品则未发现瓷体分层。从这些结果来看，FGM 的机械性能的改善是通过其成分分级得到认可的。
