Summary
Experimental and analytical studies of plasma-sprayed ZrO2-Y2O3 thick, thermoprotective-seal materials over NiCrAlY bond coats indicate the need for material to have both compliance and sufficient strength to function successfully as a thick, thermo-protective-seal material. Fibrous materials may satisfy many of these requirements. A preliminary analysis of a 25-mm cylindrical SiO2-fiber material and a 12-mm cylindrical ZrO2-fiber material indicated significant radial temperature gradients, a relatively cool interface, and generally acceptable stresses over the initial portion of the thermal cycle. Subsequent testing of these fiber-like materials in a Mach-0.3 Jet A fuel/air burner flame confirmed these results.
