Abstract
Three mole percent Y 2O 3 doped tetragonal zirconia polycrystals (TZP) and stainless steel 304 (SUS) functionally graded materials (FGM) were fabricated by slip casting. To overcome the problems of the gypsum mold (GM) in the slip casting process, an alumina mold (AM) was prepared and its properties investigated after controlling the microstructure and the sintering conditions. The optimal conditions for the dispersion of monophase and binary-phase slurries were investigated. According to these results, eleven layer TZP/SUS-FGM were fabricated with a GM and an AM. The specimens, using an AM, showed no contamination on the surface, easier thickness control of each layer and resulted in higher productivity. Especially, no symptoms of degradation were observed in the SUS made by AM. Therefore, it is more desirable to use a porous AM than a GM in the fabrication of TZP/SUS-FGM by the slip casting process.
