Title (EN) DURABLE THERMAL BARRIER COATING HAVING LOW THERMAL CONDUCTIVITY
(FR) REVÊTEMENT DE PROTECTION THERMIQUE LONGUE DURÉE À FAIBLE CONDUCTIVITÉ THERMIQUE
Abstract: front page image
(EN)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 6wt%.
(FR)Cette invention permet l’élaboration d’un revêtement de protection thermique en céramique destiné aux articles métalliques, et dont la formule est NdxZr1-xOy avec Z passé en solution, où l’on considère que 0<x<0,5 et que 1,75<y<2 et dans laquelle Z est un oxyde de métal sélectionné dans un ensemble comprenant Y, Mg, Ca, Hf ainsi que leurs mélanges. Dans une variante de la formule, Nd est intégré selon un pourcentage moléculaire pouvant aller jusqu’à 7. Dans une autre, Z est constitué d’yttrium et représente au moins 6% de la masse.
