| Zusammenfassung: | Molybdenum disilicide (MoSi2) heating elements are used as standard in large quantities as electrical resistance heating elements for the high temperature range. MoSi2 is an excellent high-temperature material, but is subject to a destructive oxidation reaction, so called pest oxidation, in the temperature range of 350 - 700 °C. This situation requires special protective measures during production. Therefore, currently only very simple shapes, based on extruded round profiles, are offered by the industry. The final product is protected from further oxidation over the entire temperature range by a dense layer of in situ formed SiO2. In order to avoid pest oxidation already during first firing, the addition of glass phase former was investigated. In this way, pest oxidation can be effectively prevented. This approach opens up new possibilities for processing. Examples of the fabrication and high temperature performance of complex shaped heating elements using thermoplastic injection molding or 3D printing as well as use of additively manufactured water soluble sacrificial molds are shown. In parallel, a coupled electrical-thermal-mechanical finite element model was developed to simulate the complex physical behavior in a spatially resolved manner. |
