AEM characterization of interfacial reactions between Ti-coating and 95% Al2O3-5% silicate ceramics

Journal of Materials Science Aims and scope Submit manuscript

Abstract

Characterization of the interface reaction region of Ti-95% Al2O3 upon exposure to heat treatment at 980 °C has been carried out to investigate changes in microstructure and chemistry of interfacial phases by using energy dispersive X-ray spectroscopy and convergent beam electron diffraction methods. Reactions of titanium-coating with an amorphous grain boundary phase and Al2O3 substrate form suicide layers and columnar Ti3Al grains at the interface respectively.
