Summary

The tesidual stresses in a ceramic sheet material used for turbine blade tip gas-path seals have been estimated. These stresses result from the plasma-spraying process which leaves the surface of the sheet in tension. To determine the properties of plasma-sprayed ZrO2-Y2O3 sheet material, its load-deflection characteristics were measured. Estimates of the mechanical properties for sheet materials were found to differ from those reported for plasma-sprayed bulk materials.
