    Abstract: Adverse interactions during initial interactions between abradable seal components are minimized by applying a coating of colloidal ceramic particles to the moving seal component. The coating is non wettable by the abradable material and provides lubrication during initial seal operation.

    Abstract: A method of adhering a ceramic facing material to an underlying substrate is disclosed. Substrates to which the concepts apply include unsupported low modulus, porous wire pads as well as low modulus, porous wire pads backed by a solid metallic form. The ceramic application techniques employed are centered around the impregnation of the regions of the pad to be ceramic coated with an underlayment coating, such as MCrAlY material, wherein the designation "M" stands for at least one of the elements from the iron cobalt and nickel group. Deep penetration of the underlayment material into the pad is achieved with a high velocity, spraying process. Ceramic material is applied over the underlayment material by conventional spraying techniques. Articles of manufacture which are suited to fabrication in accordance with the concepts disclosed herein include, but are not limited to, outer air seals, combustion chambers, and airfoils of gas turbine engines.

    Abstract: A protectively coated superalloy has improved oxidation, corrosion, and wear resistance at elevated temperatures. The protective coating is a MCrAlY type alloy having a carbon content of 0.6 to 11 percent and is characterized in a preferred embodiment by having a carbon bearing matrix containing metal carbides of 1-2 microns mean size and chromium carbides of less than 12 microns. The coating is produced in plasma spraying a mixture of MCrAlY and CR3C2 powders to form a coating having both fine carbides and coarser Cr3C2 carbides in an MCrAlY matrix. Heat treatment at 1080 DEG C after coating bonds the substrate and coating and forms further fine carbides.
