Composite Refractory Felt/Ceramic Material
Abstract
Ceramic protective coatings on combustor liners adhere better. Report discloses results of recent combustor-liner research where thick yttria stabilized zirconia ceramic was plasma-sprayed on BRUNSBOND substrates and exposed to nearly stoichiometric combustion. Combustor screening tests exposed 30 test specimens to nearly-stoichiometric flame temperatures of 3,450 degrees F (2,170 K) for 4 cycles. After completion of screening tests, all 30 specimens showed no visible evidence of discoloration or failure. There were no mudflat cracks, felt/ceramic, or backing/felt separations on any panels.
