Summary

The durability of alumina enhanced thermal barrier (AETB) tile has been found unacceptable with regard to meeting long-term performance requirements under use conditions. A tetra-ethyl-ortho-silicate (TEOS)-coated AETB tile's integrity and properties may degrade under some chemical, physical, and thermal environments. A dust erosion apparatus (DEA) was used to address the physical degradation of several AETB tile concepts. These concepts looked at the durability of the bare AETB tile, TEOS-coated AETB tile, an aluminosilicate-coated AETB tile, and an aluminosilicate-coated TEOS-coated AETB tile. Results of this investigation, as well as its test parameters, will be discussed.
