Abstract
At Eindhoven Universitu of technology a composite metal-ceramic material is being developed. It will serve as a protective confinement for a combustion heated Thermionic Energy Converter (TEC). This protective confinement of 'hot shell' consists of a composite W-TiN-SiC layer structure. The outer coating of SiC is to protect the TEC against the high temperature (1700°C) combustion atmosphere. The inner layer of tungsten serves as an emitter for the TEC. The intermediate TiN layer functions as a diffusion barrier preventing the tungsten from reacting with the SiC. The composite material is vacuum tight and thermal batigue resistant. The CVS-SiC can give adequate corrosion resistance while the tungsten is Cs-resistant and is a good thermionic emitter.
