| 제목 | Oxidation and Mechanical Properties of ZrB2-based Mixed Boride |
| 초록 | Transition metal boride characterized by high melting points, high mechanical properties and relatively good oxidation resistance in extreme environments. This family of ceramic materials has come to be known as Ultra High Temperature Ceramics(UHTCs). In this materials family, ZrB2 has the lowest theoretical density, which is combined with high electrical and thermal conductivities. This unique combination of properties makes ZrB2-based ceramics attractive for aerospace and other applications such as high-temperature electrodes, and crucibles for molten metal, hypersonic aerospace vehicles and re-usable atmospheric re-entry vehicles. These days, a matter of common interest in UHTCs is improvement of oxidation resistance by adding SiC. Besides SiC, additives such as MoSi2, ZrSi2 improve the oxidation resistance of diborides either alone or in combination with SiC. In this study, the mechanical and oxidation properties of adding other transition metal boride(TaB2, NbB2) will be discussed. |
