Oxidation behavior of AlN–SiC–TiB2 ceramics synthesized by SHS–HIP
چکیده انگلیسی

The present study aims to investigate the oxidation behavior of AlN–SiC–TiB2 composites, synthesized by self-propagating high-temperature synthesis (SHS) and hot isostatic pressing (HIP). Oxidation experiments are carried out in the temperature range from 900 °C to 1400 °C for 1–16 h under air atmosphere. The evaluation of the oxidation kinetics and the modification of the microstructure on the exposed surfaces are investigated. The weight gain per unit surface area as a function of time increased parabolically with the oxidation time from 900 °C to 1400 °C and it is accelerated sharply when the temperature is raised up to 1400 °C. The oxidation products on the sample surfaces are mainly constituted of crystalline mullite and titanium oxide.
