摘要： A method of manufacturing a component from a nickel-based superalloy comprises the steps of: providing a vacuum induction casting furnace; positioning a component mould onto a chill plate within the furnace; casting a component blank; peening the surface of the component blank; applying a surface modification technique to the surface of the component blank; solution heat treating the component blank at or above the γ′-solvus temperature for the superalloy; and precipitation heat treating the component blank.

摘要： A coated article and method for producing the coated article are described. The article is coated with a system which provides protection against oxidation and corrosion and which significantly reduces the substrate temperature. An MCrAlY layer is applied to the article to be protected and a columnar grain ceramic is applied by vapor deposition to the MCrAlY coated article. An alumina layer which exists between the MCrAlY layer and the columnar ceramic layer provides for the adherence of the columnar layer to the MCrAlY layer. An important feature of the invention is that the interface between the MCrAlY layer and the alumina layer has a low surface roughness and this greatly improves the columnar ceramic layer adherence.

摘要： A method of polishing a metallic workpiece includes: mounting the workpiece in a hopper; loading the hopper with a polishing media comprising, by weight percent, more than 98% metallic chips, less than 2% liquid, and less than 0.05% abrasive; and oscillating the hopper for a run time, thereby generating a flow of the polishing media over the workpiece, until a predetermined surface finish is achieved on the workpiece.

摘要： An article may include a substrate defining a surface imperfection and a coating deposited over the substrate. The coating does not substantially reproduce the surface imperfection, and the coating comprises mullite and at least one rare earth silicate, rare earth oxide, alumina, boron oxide, alkali metal oxide, alkali earth metal oxide, silicon, barium strontium aluminosilicate, barium aluminosilicate, strontium aluminosilicate, calcium aluminosilicate, magnesium aluminosilicate, or lithium aluminosilicate. In some examples, the coating may be a first coating deposited from a slurry over the substrate, and a second coating may be deposited over the first coating. In other examples, a first coating that substantially reproduces the surface imperfection may be deposited over the substrate, and the coating that does not substantially reproduce the surface imperfection may be deposited over the first coating.

摘要： A method of polishing an outer surface of a ceramic coated gas turbine engine component includes applying a rotating diamond brush to the outer surface. The brush is configured to achieve a uniform finish of 150 microinches RA or less over the surface. The brush contains diamond impregnated bristles, and is affixed to a rotary head of a robotic arm. A force sensing controller limits brush forces against the component. The component disclosed is a hot section turbine vane designed for directional control of high temperature, high-pressure combustion gases, but the method may be applied to other components utilized in similar aerospace applications. The polished coating provides an improved thermal barrier for maintaining structural integrity of the component in environments having temperatures ranging up to 2,000 degrees Celsius. The method limits abrasive removal of ceramic material to only 0.0005 to 0.00075 inch, and saves time and expense over past practices.
