Abstract

The microstructures and the reaction temperatures of Ti-ZrO₂ (CaO stabilized) and TiAl-ZrO₂ (CaO stabilized) systems were researched at different heating rates by SEM and differential thermal analysis (DTA), and the reaction kinetics parameters in the two systems were calculated by means of Kissinger equation. The results show that, with the increase of heating rates, the chemical reactions of the two systems are weakened gradually, and the initial reaction temperatures increase. Compared to Ti-ZrO₂ (CaO stabilized) system, the initial reaction temperature in the TiAl-ZrO₂ (CaO stabilized) system increases about 170°C and the interfacial reaction between Ti and ZrO₂ (CaO stabilized) is weakened. The activation energies of the two systems are 1348 kJ/mol and 1675 kJ/mol, and the reaction orders are 1.51 and 1.59, respectively.
