ABSTRACT:
This invention provides a thermal barrier ceramic coating for application to a metallic article, with the ceramic coating having a formula of NdxZr1-xOywith Z dissolved in, where 0<x<0.5 and 1.75<y<2 and wherein Z is an oxide of a metal selected from the group consisting of Y, Mg, Ca, Hf and mixtures thereof. In one embodiment Nd is added at a level up to 7 mole %. In another embodiment Z is yttrium and is added at a level of at least 6 wt %.
