Development of Highly Heat-Resistant Components of SiC, Especially for Vehicle Gas Turbine Applications

摘要

Given working temperatures in excess of 1000 C, corrosion and oxidation resistance as well as thermoshock resistance requirements are discussed. The improvement of material quality, in particular heat conductance, and of manufacturing technology are described. Prototypes of turbine rotors and rotor blades, combustion chambers, and flame tubes were produced and tested. Promising test results under simulation application conditions are reported.
