For the purpose of investigating ultra-high temperature oxidation, a novel induction heating facility has been established. The oxidation kinetics of several typical ultra-high temperature materials (UHTMs), including two graphite-based composites (C/C and ZrB2/C) and two ternary Zr-Al-C ceramics (Zr2Al3C4 and Zr2[Al(Si)]4C5), were tested by utilizing this facility. It has been identified that the tested cylindrical samples with dimensions of Φ 20？mm × 20？mm can be oxidized uniformly. The maximum temperature of 2450°C can be achieved on graphite-based composites, and the oxygen partial pressure can be controlled in the range of 102–105？Pa. This novel technique exhibits many advantages, such as an extremely high heating rate of about 20°C/s, easy controlling of temperature and gas pressure, low energy consumption, low cost, and high efficiency. Therefore, it provides a potential way for profoundly investigating the ultra-high temperature oxidation behaviors of UHTMs. |
