A method for constructing a turbine shroud structure includes providing a metal substrate with a plurality of pegs extending therefrom. A ceramic sealing layer of zirconium oxide with about 20 weight percentage magnesium is applied to the peg-metal substrate structure. Intermediate bonding layers may be applied between the ceramic sealing layer and the peg-metal substrate structure. The ceramic sealing layer is then heat treated to a temperature of 1100 DEG C. to increase the rub wear of the ceramic sealing layer and to reduce the thermal stress therein. |
