Thermal barrier coats represent perhaps the most promising and exciting development in superalloy coatings.
Any mechanism by which the temperature limits can be raised by overcoming hot-section material restraints is of significant interest, and thermal barrier coatings offer this potential.
A cooling film ejected on the outer surface of the vane isolates the metal from hot gases in the vicinity, and thermal barrier coating on the vane reduces heat transfer because of its low heat conductivity.
A thermal barrier coating is applied to the inner surface of the metal shrouds.
