A coating material, particularly a thermal barrier coating, for a component intended for use in a hostile environment, such as the superalloy turbine, combustor and augmentor components of a gas turbine engine. The coating material is zirconia that is stabilized with yttria and to which an oxide additive of niobia or titania is alloyed to reduce and stabilize the thermal conductivity of the coating.

Un material de capa, particularmente una capa termal de la barrera, porque un componente pensó para el uso en un ambiente hostil, tal como los componentes superalloy de la turbina, del combustor y del aumentador de un motor de turbina de gas. El material de capa es el zirconia a que se estabiliza con yttria y a cuál se alea un añadido del óxido del niobia o del titania para reducir y para estabilizar la conductividad termal de la capa.
