摘要： A method and apparatus for forming a multilayer thermal barrier coating such that the coating is composed of substantially homogeneous layers of different ceramic materials. The method entails supporting an article within a coating apparatus and in proximity to ceramic ingots of the different ceramic materials, and then simultaneously directing electron beams at both ingots so as to maintain a portion of each ingot in a molten state. According to a particular aspect of this invention, vapors of both ceramic materials coexist within the coating apparatus, yet each ceramic material is sequentially deposited onto the article by sequentially interrupting exposure of surfaces of the article to the vapors, such that the vapors form homogeneous successive layers on the surface. Exposure of the article to one or more of the vapors can be interrupted with a baffle, such that the vapor of only one of the ceramic ingots is directly deposited on a given surface of the article at any instant. The baffle can be employed in conjunction with the article being rotated at a constant or variable speed, and/or being translated above the members within the vessel to alter the relative thicknesses of the ceramic and an intermediate layer that is formed between adjacent layers and is composed of a mixture of the ceramic materials.
摘要翻译：一种用于形成多层热障涂层的方法和装置，使得涂层由不同陶瓷材料的基本均匀的层组成。该方法需要在涂覆装置内并且靠近不同陶瓷材料的陶瓷锭支撑制品，然后同时引导两个锭子处的电子束，以便将每个锭的一部分保持在熔融状态。根据本发明的特定方面，两种陶瓷材料的蒸汽在涂覆设备中共存，但是每个陶瓷材料通过依次地将制品的表面暴露于蒸气而顺序地沉积到制品上，使得蒸气形成均匀的连续表面上的层。物品暴露于一个或多个蒸气可能会被挡板中断，使得只有一个陶瓷锭的蒸汽在任何时刻直接沉积在物品的给定表面上。挡板可以与制品以恒定或可变速度一起旋转和/或在容器内的构件上方平移以改变陶瓷和相邻层之间形成的中间层的相对厚度，并且是由陶瓷材料的混合物组成。

摘要： A thermal barrier coating adapted to be formed on an article subjected to a hostile thermal environment while subjected to erosion by particles and debris, as is the case with turbine, combustor and augmentor components of a gas turbine engine. The thermal barrier coating is composed of a metallic bond layer deposited on the surface of the article, a ceramic layer overlaying the bond layer, and an erosion-resistant composition dispersed within or overlaying the ceramic layer. The bond layer serves to tenaciously adhere the thermal insulating ceramic layer to the article, while the erosion-resistant composition renders the ceramic layer more resistant to erosion. The erosion-resistant composition is either alumina (Al.sub.2 O.sub.3) or silicon carbide (SiC), while a preferred ceramic layer is yttria-stabilized zirconia (YSZ) deposited by a physical vapor deposition technique to have a columnar grain structure.

摘要： A bond-coated substrate is protected with an alpha alumina layer. The alpha alumina layer may be deposited as a relatively thick layer directly onto the bond-coated substrate. In this embodiment, no further ceramic layer overlies the alpha alumina layer. Other ceramics may be mixed into the alpha alumina layer, however. In another embodiment, a layer of a ceramic other than alpha alumina is deposited over the bond-coated substrate, and an alpha alumina layer is deposited over the ceramic layer.

摘要： A thermal insulating ceramic layer for use on metal alloy components exposed to hostile thermal and chemical environment, such as a gas turbine engine used to generate electricity. The preferred thermal barrier layer is formed using dense vertical cracking and formed of zirconia that is partially stabilized by yttria in a preferred amount of less than 4 weight percent and about 1 weight percent Hafnia. The ceramic layer is optimized to protect the underlying superalloy component from erosion, chipping, and handling, while reducing the cost of the protective layer. An alternative method of preparing the thermal barrier coating uses electron beam physical vapor deposition.

摘要： An article having a substrate is protected by a thermal barrier coating system. An interfacial layer contacts the upper surface of the substrate. The interfacial layer may comprise a bond coat only, or a bond coat and an overlay coat. The interfacial layer has on its upper surface a preselected, controllable pattern of three-dimensional features, such as grooves in a parallel array or in two angularly offset arrays. The features are formed by an ablation process using an ultraviolet laser such as an excimer laser. A ceramic thermal barrier coating is deposited over the pattern of features on the upper surface of the interfacial layer.

摘要： A method for producing a thermal barrier coating system on an article that will be subjected to a hostile environment. The thermal barrier coating system is composed of a metallic bond coat and a ceramic thermal barrier coating having a columnar grain structure. The method generally entails forming the bond coat on the surface of a component, and then grit blasting the bond coat with an abrasive media having a particle size of greater than 80 mesh. The component is then supported within a coating chamber containing at least two ingots of the desired ceramic material. An absolute pressure of greater than 0.014 mbar is established within the chamber containing oxygen and an inert gas. Thereafter, the ceramic ingots are vaporized with an electron beam such that the vapor deposits on the surface of the component to form a layer of the ceramic material on the surface.

摘要： A thermal insulating ceramic layer for use in a thermal barrier coating system on a component designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The ceramic layer is formed of zirconia stabilized by yttria and characterized by a columnar grain structure in which a monoclinic phase is present. To attain the monoclinic phase, the ceramic layer contains less than six weight percent yttria, with about two to five weight percent yttria being preferred. The ceramic layer is preferably part of a thermal barrier coating system that includes a substrate and a bond coat adhering the ceramic layer to the substrate. To obtain the desired columnar grain structure, the ceramic layer is deposited by a PVD technique, preferably EBPVD.

摘要： Evaporated ceramic coatings are prepared by furnishing an ingot of a ceramic material, treating the ingot to reduce sources of gas within the ingot, and evaporating the ceramic material in the ingot by melting the surface of the ingot with an intense heat source. The evaporated ceramic is deposited upon a substrate as the ceramic coating. The reduced gas content of the ingot decreases the incidence of spitting and eruptions from the molten surface of the ingot, thereby improving the quality of the deposited coating, and facilitating increases in evaporation rates and coatings process production rates.

摘要： A method is provided for physical vapor deposition of ceramic thermal barrier coatings and articles made therefrom Impurity levels in conventional yttria stabilized zirconia source materials have caused undesired spitting (eruptions) due to a combined effect of various impurities thereby requiring relatively low evaporation rates to control the level of spitting during the process. The present method provides a high purity source material having a purity index sufficiently low to result in reduced spitting in the vapor deposition process and to permit in evaporation rates. Reducing the density of the source material has also been found to reduce spitting. The method permits higher processing rates and/or reduced levels of spitting.
