TiAl基合金与陶瓷界面反应的研究
摘要
借助电子探针微区分析仪、维氏显微硬度计、光学和电子显微镜对TiAl合金与Al2 O3
ZrO2 以及经CaO稳定的ZrO2 3种陶瓷型壳的界面反应进行了研究分析。结果表明
这 3种材料的化学稳定性依次升高
而经CaO稳定的ZrO2 型壳与TiAl反应层的厚度仅为 5 0 μm
故可望用作钛铝合金精密铸造型壳面层材料
Abstract
Interface reactions of TiAl alloy with three varieties of ceramic shell molds
including Al 2O 3
ZrO 2
ZrO 2 stabilized with CaO
were examined by EPMA
Vicker microhardness meter
optical microscope and SEM. The results showed that the chemical stability of these materials increased in the above sequence. The thickness of interface reactive layer between ZrO 2 stabilized with CaO and TiAl was merely 50 μm
so it can be applied to face coating materials in investment casting for TiAl alloy.
