| Research Abstract |
In order to establish quantitative estimation technology to measure oxidation rates of high temperature materials, this study has clarified that it is required to determine partial pressure of oxygen on the surface of the materials PO2-s. To demonstrate this assertion, procedures to determine PO2-ss in thermo-balances have developed for the active and passive oxidation behaviors of SiC, which has been used in reusable spaces vehicles. Next, oxidation behaviors of ZrB2-SiC were examined.
