| 20090308733 | Thermal Barrier Coating Compositions, Processes for Applying Same and Articles Coated with Same - A process of coating an article includes the steps of (1) forming a layer of a ceramic based compound on an article; (2) providing a solution containing a metal as a particulate having a diameter of about 10 nanometers to about 1000 nanometers and present in an amount of about 25 percent to about 50 percent by volume of the solution; (3) contacting the ceramic based compound layer with the solution; (4) drying the article; and (5) optionally repeating steps (3) and (4). | 12-17-2009 |
| 20100047075 | Thermal Barrier Coating Compositions, Processes for Applying Same and Articles Coated with Same - A process of coating an article includes the steps of (1) applying a ceramic compound to at least one surface of an article to form a layer of ceramic compound; (2) applying at least one inert compound upon the ceramic 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) A | 02-25-2010 |
| 20100098865 | DURABLE REACTIVE THERMAL BARRIER COATINGS - A turbine engine component is provided which has a substrate and a thermal barrier coating applied over the substrate. The thermal barrier coating comprises at least one layer of a first material selected from the group consisting of a zirconate, a hafnate, a titanate, and mixtures thereof, which first material has been mixed with, and contains, from about 25 to 99 wt % of at least one oxide. The at least one oxide comprises at least one oxide of a material selected from the group consisting of lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, indium, and yttrium. If desired, a metallic bond coat may be present between the substrate and the thermal barrier coating system. A method for forming the thermal barrier coating system of the present invention is described. | 04-22-2010 |
| 20100119718 | Dense protective coatings, methods for their preparation and coated articles - A method for depositing a protective coating on a complex shaped substrate includes the steps of: (1) dipping a complex shaped substrate into a slurry to form a base coat thereon, the slurry comprising an aqueous solution, at least one refractory metal oxide, and at least one transient fluid additive present in an amount of about 0.1 percent to 10 percent by weight of the slurry; (2) curing the dipped substrate; (3) dipping the substrate into a precursor solution to form a top barrier coat thereon; and (4) heat treating the dipped, cured substrate to form a protective coating. | 05-13-2010 |
| 20100136241 | SILICATE RESISTANT THERMAL BARRIER COATING WITH ALTERNATING LAYERS - A thermal barrier coating system for use on a turbine engine component which reduces sand related distress is provided. The coating system comprises at least one first layer of a stabilized material selected from the group consisting of zirconia, hafnia, and titania and at least one second layer containing at least one of oxyapatite and garnet. Where the coating system comprises multiple first layers and multiple second layers, the layers are formed or deposited in an alternating manner. | 06-03-2010 |
| 20100196605 | Yttria-Stabilized Zirconia Coating with a Molten Silicate Resistant Outer Layer - A turbine engine component is provided which has a substrate, a yttria-stabilized zirconia coating applied over the substrate, and a molten silicate resistant outer layer. The molten silicate resistant outer layer is formed from gadolinia or gadolinia-stabilized zirconia. A method for forming the coating system of the present invention is described. | 08-05-2010 |
| 20110086179 | THERMAL BARRIER COATING WITH A PLASMA SPRAY TOP LAYER - A turbine engine component has a substrate, a thermal barrier coating deposited onto the substrate, and a sealing layer of ceramic material on an outer surface of the thermal barrier coating for limiting molten sand penetration. | 04-14-2011 |
| 20110200759 | OXIDATION RESISTANT COATINGS, PROCESSES FOR COATING ARTICLES, AND THEIR COATED ARTICLES - A process for applying an oxidation resistant coating to an article includes the steps of mixing at least about 10% by volume to up to about 99% by volume of a slurry at least one silica based material having a viscosity of about 1×10 | 08-18-2011 |
