Abstract: A method for applying an abrasive comprises: applying, to a substrate, the integral combination of: a self-braze material; an abrasive; and a matrix in which the abrasive is at least partially embedded; and heating to cause the self-braze material to braze to the substrate. The heating leaves at least a portion of the self-braze material with a composition comprising, in weight percent: cobalt 2.5-13.5; chromium 12-27; aluminum 5-7; yttrium 0.0-1.0; hafnium 0.0-1.0; silicon 1.0-3.0; tantalum 0.0-4.5; tungsten 0.0-6.5; rhenium 0.0-2.0; molybdenum 0.1-1.0; and the balance nickel.

Abstract: An abrasive sheath for application to a component surface is disclosed. The abrasive sheath may comprise a metallic layer and an abrasive layer plated on a surface of the metallic layer. The abrasive layer may include a metal matrix and abrasive particles protruding from the matrix. An exposed surface of the metallic layer of the abrasive sheath may be joinable to the component surface by a heat treatment.

Abstract: A method of stripping an engine component may comprise applying an acidic gel solvent to a coating of a surface of the engine component, leaving the acidic gel solvent on the surface of the engine component for a predetermined duration, and removing the acidic gel solvent from the surface of the engine component. The method may further include mixing an acid with a gelling agent to form the acidic gel solvent. The acid may comprise hydrochloric acid. The gelling agent may comprise a cellulosic material. The gelling agent may comprise a carbohydrate. The method may further include rinsing the acidic gel solvent from the surface of the engine component. The coating may comprise at least one of a diffusion coating or an overlay coating.
