摘要
A study on the interaction between TiAl alloy and zirconia was carried out in argon atmosphere. Themicrographic observations of the cross-section perpendicular to the interface were obtained using a scanning electronmicroscope with a dedicated energy dispersive spectrometer (SEM/EDS). The results showed that firstly TiAl alloyspreads on the ceramic surface, and then infiltrates into the pores between ceramic particles accompanied by a chemicalreaction. The whole ceramic mold is broken into tiny blocks. A multiple fission reaction mechanism was developed toexplain the interaction between TiAl alloy and zirconia.
