摘要： Methods and systems for in situ cleaning of internal cooling circuits of a turbine engine with detergent that provide cleaning a turbine engine that includes circumferentially arranged internal impingement cooling circuits that each include a baffle plate configured to air cool a respective surface or component of the turbine engine. Detergent is introduced through the outer wall and proximate to a back side of a baffle plate such that the detergent passes through at least aperture in the baffle plate and acts at least upon the surface or component that the baffle plate is configured to cool. The detergent may also act on the front side of the baffle plate that is proximate to the surface or component.

摘要： The present disclosure provides methods and systems for in situ cleaning of hot gas flowpath components of a turbine engine that form portions of a hot gas flowpath extending through the turbine. The hot gas flowpath components may include a layer of accumulated contaminants on first portions thereof that form a respective portion of the hot gas flowpath. The first portions may include a thermal battier coating (TBC), and the layer of accumulated contaminants may overlie the TBC and at least partially infiltrate into the TBC. The accumulated contaminants may include CaO—MgO—Al2O3-SiO2 (CMAS) partial melt. The methods may include introducing an acid-including detergent into the hot gas flowpath of the turbine engine and onto the hot gas flowpath components to clean the accumulated contaminants from the first surfaces of the components.

摘要： The present disclosure relates to a titanium-containing article casting mold composition comprising calcium aluminate and an X-ray or Neutron-ray detectable element. Furthermore, present embodiments teach a method for detecting sub-surface ceramic inclusions in a titanium or titanium alloy casting by combining calcium aluminate, an element more radiographically dense than the calcium aluminate, and a liquid to form a slurry; forming a mold having the calcium aluminate and the radiographically dense element from the slurry; introducing a titanium aluminide-containing metal to the radiographically dense element-bearing mold; solidifying said titanium aluminide-containing metal to form an article in the mold; removing the solidified titanium aluminide-containing metal article from said mold; subjecting the solidified titanium aluminide-containing article to radiographic inspection to provide a radiograph; and examining said radiograph for the presence of the radiographically dense element on or in the article.
