Abstract

In order to clearly understand the details of ZrO2 formation during ablation, high intensity continuous laser was chosen to irradiate ZrB2/SiC. The results reveal that there are two different modes of ZrO2 formation depending on whether liquid SiO2 is present. When liquid SiO2 is present, ZrO2 generated by the oxidation of ZrB2 is firstly dissolved into SiO2. Then, ZrO2 will precipitate again, the temperature will decrease and the SiO2 will evaporate. Otherwise, the ZrB2 will be oxidized to ZrO2 directly. View Full-Text
