Research Abstract

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.
