Summary

The effect of the salt deposits on the mechanical strength of Nicalon fiber-reinforced calcium aluminosilicate was examined. Tensile test on specimens exposed to sodium sulfate at 900°C were conducted. Results of these tests were compared to the baseline mechanical properties of the as-received, and uncoated specimens. Degradation mechanisms from the salt deposits which were investigated using SEM and x-ray analysis, are also discussed.
