    • A method of 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 is particularly suited for completely removing a thermal insulating ceramic layer of thermal barrier coating system that includes a metallic bond coat, such as a diffusion aluminide or MCrAlY coating, between the surface of the component and the ceramic layer, while leaving the bond coat substantially undamaged. Furthermore, the method of this invention includes a technique by which ceramic material within cooling holes in the component can be removed without damaging the underlying bond coat. The process steps generally include removing the ceramic layer from the surface of the component by subjecting the ceramic layer to a caustic solution at an elevated temperature and pressure, and then removing ceramic material from the cooling hole by carefully directing a high-velocity fluid stream into the cooling hole. According to this invention, the high-velocity fluid stream is able to overcome the compressive stresses that otherwise anchor the ceramic in the cooling hole, yet does not remove or damage the bond coat underlying the ceramic.
    • 在设计用于恶劣热环境中的部件(例如燃气涡轮发动机的涡轮机,燃烧器和增压器部件)上修复热障涂层的方法。 该方法特别适于完全去除在元件表面和陶瓷层之间包括金属粘合涂层(例如扩散铝化物或MCrAlY涂层)的热障涂层系统的绝热陶瓷层,同时留下粘合涂层 基本没有损坏。 此外,本发明的方法包括可以除去组件内的冷却孔内的陶瓷材料而不损坏下面的粘合涂层的技术。 工艺步骤通常包括通过在升高的温度和压力下对陶瓷层进行苛性碱溶液从部件的表面除去陶瓷层,然后通过小心地将高速流体流引导到冷却孔中,从陶瓷材料中除去陶瓷材料 冷却孔。 根据本发明,高速流体流能够克服否则将陶瓷固定在冷却孔中的压缩应力,但是不会去除或损坏陶瓷下面的粘合涂层。

    • An environmental resistant spot type coating is provided on a selected, discrete surface area of a high temperature operating article, by applying to the area a layer of at least one of the elements selected from Pt, Rh and Pd, and preferably Pt, to a thickness of about 0.0002" to less than 0.0006" and an average distribution of at least about 0.07 grams per square inch. The layer is heated at about 1800-2050.degree. F. for about 1/2-4 hours to diffuse the element with the surface area. Then the layer is aluminided to provide an average total coating thickness of about 0.001-0.005". The article provided includes an environmental resistant additive coating diffused with the selected discrete area. The coating comprises an outer portion of at least about 17 wt. % of the selected element, and an aluminide of the surface area or substrate. In one form, the outer portion is a two phase outer portion: a first phase of an aluminide of the selected element at a content of at least about 40 wt. % interspersed with a second phase comprising an aluminide in which Al is at least about 20 wt. %. Between the outer portion and the surface area is an inner portion which is a diffusion zone comprising diffused selected element along with an aluminide and/or elements diffused from the surface area.
