GEL SOLVENT AND METHOD OF REMOVING DIFFUSION AND OVERLAY COATINGS IN GAS TURBINE ENGINES |
| 摘要 |
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. |
