Article Preview

Three mole percent Y2O3 doped tetragonal polycrystals (TZP) and stainless steel functionally graded materials (FGMs) were fabricated by slip casting. The optimal conditions for control of interfacial cracks by adjusting shrinkage of each component and temperature gradient were investigated. Experimental results showed that sintering shrinkage mismatch of adjacent intermediate interlayer could cause interface cracks, as well as speedy temperature dropping rate in the cooling process. Based on suitable adjusting of sintering shrinkage and controlling of cooling rate, a satisfying interfacial microstructure without apparent cracks for FGM of 3Y-TZP/SUS with three intermediate layers was obtained.
