    • A chemical composition and method for repairing a thermal barrier coating on a component designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The method repairs a thermal barrier coating on a component that has suffered localized damage to the thermal barrier coating. After cleaning the surface area of the component exposed by the localized spallation, a paste-like mixture of a ceramic composition comprising ceramic powders and nano-sized ceramic materials in a binder is applied to the surface area of the component, and is optionally smoothed using mechanical means. The composition is then allowed to dry and cure to form a dried coating having polymeric characteristics. Upon subsequent heating, the dried coating reacts to produce a glassy ceramic repair coating. Due to the thixotropic properties of the coating composition upon application to a component, the repair method can be performed in-situ while the component remains installed in its operating environment.
    • 用于修复设计用于恶劣热环境的部件上的热障涂层的化学组成和方法,例如燃气涡轮发动机的涡轮机,燃烧器和增压器部件。 该方法修复已经对热障涂层局部损坏的部件上的热障涂层。 在清洁通过局部剥离暴露的部件的表面积之后,将包含陶瓷粉末和纳米尺寸陶瓷材料的陶瓷组合物的粘合剂的糊状混合物施加到部件的表面区域,并且可选地使用 机械手段。 然后将组合物干燥并固化以形成具有聚合特性的干燥涂层。 随后加热,干燥的涂层反应生成玻璃状陶瓷修补涂层。 由于涂料组合物在施用于组分时的触变性能,可以在组分保持安装在其操作环境中时原位进行修复方法。

    • A thermal coating includes a substrate, a first coating layer, and a second coating layer. The substrate is selected from the group consisting of superalloys and ceramic matrix composites. The first coating layer comprises an alumina powder, a silica binder, and at least one additive selected from either a first group or a second group. The second coating layer comprises at least one of zinc titanate or cerium oxide. A method for applying a thermal coating system includes spraying a bond coat mixture onto a substrate using a liquid electrostatic sprayer. The bond coat mixture comprises an alumina powder, a silica binder, and at least one additive selected from either a first group or a second group. The method further includes applying a top coat mixture onto the bond coat mixture, wherein the top coat mixture comprises at least one of zinc titanate or cerium oxide.
