J191033 Creation and evaluation of functionally gradient material by powder molding method

Abstract

Functionally Gradient Material, FGM is a composite constituted by two components, characterized by a compositional gradient from one component to the other. The strength and functional properties of FGM differ from simple bonded dissimilar material between two different components. In the present study, FGM based on Ni and Zr02 were manufactured by powder molding method and the Vickers hardness tests were carried out. The creep tests were also carried out at about 2100K using the plasma jet equipment. It was shown that Vickers hardness and creep rupture life of Ni Zr02 FGM increase with increasing the sintering time during manufacturing process of this FGM.
