Abstract:
Lam ina ted po rous A l2O3 /ZrO2 ceram ics was successfu lly prepared by ge lcasting using laye r-by- layer techn ique. Therm al shock resistance of these lam inated porous ceram ics w as investigated. The resu lts show that the layered porous ceram ics takes on a h igh therm a l shock resistance compared tom ono lith ic porous ce ram ics though they hav e sim -i lar po rosity. The cr itica l difference tem perature ( ΔTc ) and residua l streng th improve from about 300℃and 20M Pa ( ΔT = 800℃ for mono lithic ceram ics w ith 32% po ros ity to 500℃ and 30MPa ( Δ T = 1 100℃ for layered porous ceramics.
