摘要
选择纯单斜氧化锆(m-ZrO2)、含3%(mol)Y2O3部分稳定氧化锆(3Y-PSZ)和含12%(mol)CeO2部分稳定氧化锆(12Ce-PSZ),添加30%(?)金属Mo,采用粉末冶金方法制备了相对密度大于95%的致密金属陶瓷试样,将金属陶瓷于1600℃下在IF钢液和Al2O3-CaO-MgO预熔渣中静态侵蚀4 h.结果表明,金属陶瓷在不同介质中的侵蚀行为与陶瓷基体相关,纯m-ZrO2基体金属陶瓷抗钢液侵蚀性能较好,3Y-PSZ基体金属陶瓷抗熔渣侵蚀性能较好.钢液对金属陶瓷的侵蚀主要是形成铁钼金属间化合物,熔渣的侵蚀主要是陶瓷基体与渣中CaO反应生成CaZrO3.
Three ceramics, pure monolithic zirconia（m-ZrO2）, 3%（mol） Y2O3 doped partially stabilized zirconia（3Y-PSZ） and 12%（mol） CeO2 doped PSZ（12Ce-PSZ）, were chosen for preparing three cermets by adding 30%（？） Mo. The relative density of the cermets was over 95%. Their static corrosion tests were conducted in a tube furnace at 1600℃ for 4 h in molten IF steel and Al2O3-CaO-MgO slag respectively, and their corrosion behaviors observed. The results show that the cermet with pure m-ZrO2 has better corrosion resistance to liquid steel while the cermet with 3Y-PSZ has better corrosion resistance to molten slag. The corrosion of cermet by liquid steel is mainly involved with formation of intermetallic compounds between Fe and Mo, and the corrosion of cermet by molten slag mainly with the reaction of ZrO2 and CaO in slag for formation of CaZrO3.
