| Abstract: | Ti-ZrO 2 functionally gradient materials (FGM) were prepared using powder metallurgical technique. The gradient distribution of chemical composition, the interfacial microstructure between layers and the bonding states of phases between Ti and ZrO 2 were investigated by means of XRD, SEM, EDS and TEM. Experimental results show that the microstructure of Ti-ZrO 2 FGM exhibit a transition from titanium particles dispersion in zirconia matrix to an inverse dispersion of zirconia in titanium with increase of Ti content. There are no reaction product in the Ti/ZrO 2 interface, and the bonding state between Ti and ZrO 2 was physical in the composite. The phase composition of the composite are mainly titanium and tetragonal zirconia with a few monoclinic zirconia. |
