A method of cleaning a component within a turbine that includes disassembling the turbine engine to provide a flow path to an interior passageway of the component from an access point. The component has coked hydrocarbons formed thereon. The method further includes discharging a flow of cleaning solution towards the interior passageway from the access point, wherein the cleaning solution is configured to remove the coked hydrocarbons from the component.

Methods of cleaning a component within a turbine engine

A coating including a plurality of indicator oxide nanoparticles, a binder, and a wetting agent. A sulfidation corrosion mitigation coating including: a sulfidation corrosion mitigation material, a binder, and a plurality of indicator oxide nanoparticles. An article including a metal alloy substrate having the sulfidation corrosion mitigation coating thereon is also provided. The sulfidation corrosion mitigation coating can include a first indicator layer containing indicator oxide nanoparticles disposed on the surface of the metal alloy substrate. Methods for inspection of an article having a coating containing a plurality of indicator oxide nanoparticles is also provided.

Inspectable coatings and methods for using

In one embodiment, a method of manufacturing a metal part using a laser or electron beam during a powder bed additive manufacturing process includes melting each of a number of layers of metal powder of the metal part with an effective amount of energy using the laser or electron beam to form the metal part such that at least one or more portions of the metal part have a critical amount of residual strain. The method also includes performing a heat treatment on the metal part that transforms the residual strain into substantially distributed coincidence site lattice (CSL) grain boundaries, low angle grain boundaries, or both in the metal part.
