Thermal barrier coating compositions, processes for applying same and articles coated with same |
摘要 |
A process of coating an article includes the steps of (1) applying a ceramic based compound to at least one surface of an article to form a layer of ceramic based compound; (2) applying at least one inert compound upon the ceramic based compound layer to form a protective layer, wherein the at least one inert compound is composed of a first inert compound having a cubic crystalline structure of formula (I) A3B2X3O12, or a second inert compound comprising a hexagonal crystalline structure of formula (II) A4B6X6O26, or a mixture of the first inert compound and the second inert compound; (3) optionally drying the coated article; (4) optionally repeating steps (2) and (3); and (5) heat treating the coated article.
