摘要:
采取凝胶注模工艺层层沉积制备梯度氧化铝/氧化锆多孔陶瓷,研究了层状多孔氧化铝/氧化锆陶瓷的抗热震行为.研究结果表明,同单层多孔陶瓷相比,层状多孔陶瓷表现出更加优良的抗热震性能.临界抗热震温差由气孔率为32%的单层结构的300℃上升到层状结构的500℃,且层状结构多孔陶瓷在温差高达1 100℃淬火后剩余强度为30 MPa,而单层陶瓷在温差800℃淬火后仅为20 MPa.
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.
