Publication number: 20090075024Abstract: A method for producing a ceramic thermal barrier coating on a component part for use in compressor and turbine components by a vapor depositing process, and a ceramic thermal barrier coating, is disclosed. The method includes: a) provision of a ceramic vapor for depositing on the component part; b) depositing of the ceramic vapor on the component part to form a thermal barrier coating having a columnar structure, the columns being oriented substantially perpendicular to a surface of the component part; and c) varying of at least one method parameter during method step b) such that the resultant thermal barrier coating has columns of alternating decreasing and increasing diameters. The ceramic thermal barrier coating has a columnar structure and the columns are oriented substantially perpendicular to a surface of the corresponding part. The columns have alternately decreasing and increasing diameters.Type: ApplicationFiled: March 2, 2007Publication date: March 19, 2009Applicant: MTU Aero Engines GmbHInventor: Thomas Cosack

Publication number: 20070125639Abstract: A method and apparatus for producing a protective layer to prevent oxidation and/or corrosion for components, in particular for components of a gas turbine, are disclosed. In the method a component having a substrate surface and a substrate composition are provided. Then a coating material is supplied, where the coating material contains at least platinum and aluminum. Then the coating material consisting of at least platinum and aluminum is deposited on the component to be coated in a PVD process (Physical Vapor Deposition Process). Platinum and aluminum are deposited jointly with a single PVD process on the component to be coated.Type: ApplicationFiled: November 4, 2004Publication date: June 7, 2007Applicant: MTU Aero Engines GmbHInventors: Thomas Cosack, Wolfgang Eichmann

Patent number: 6440499Abstract: A method for producing a corrosion-resistant and an oxidation-resistant coating on a component in which a slurry is formed by mixing a binder solution with (1) a base powder selected from the group consisting of (a) MCrAlY wherein M is Ni or Co or both, (b) NiCrAl and (c) mixtures of (a) and (b) with (2) an added powder of Al, Pt, Pd, Si or mixtures thereof, each of the said powders having a grain size between 5 and 120 &mgr;m. The slurry is applied onto a component made of a superalloy based on nickel or cobalt. The slurry is hardened on the component to form a hardened slurry coating by heating the slurry to a temperature between room temperature and 450° C., and the hardened slurry coating is heated, to produce diffusion thereof into the component, at a temperature between 750° C. and 1250° C.Type: GrantFiled: September 8, 2000Date of Patent: August 27, 2002Assignee: MTU Aero Engines GmbHInventors: Gerhard Wydra, Thomas Cosack, Wolfgang Hinreiner
