Publication number: 20080152802Abstract: A method for cleaning, method and device for the application of a protective medium to a turbine blade, and a method for placing cooling bores in a turbine blade is disclosed. For this purpose, hot supercritical carbon dioxide is used as a tempering and/or cleaning medium and compressed and decompressed one or more successive times. The cleaning medium is decompressed to a pressure at which the gas assumes a volume that is a multiple of the volume of the compressed cleaning medium in the pressure tank. In so doing, it is possible to remove particulate and other impurities, even from recesses, blind holes, or open hollow spaces.Type: ApplicationFiled: January 30, 2007Publication date: June 26, 2008Applicant: MTU Aero Engines GmbHInventors: Erwin Bayer, Max Niegl, Detlev Schuenke, Michael Unger, Karsten Loehr
