20090255828 | Device and Method for Removing Surface Areas of a Component - Apparatus and process for removing surface regions of a component. The prior art involves removing surface regions of a metallic component by means of electrochemical processes. The electrochemical process is accelerated by the use of a current pulse generator. | 10-15-2009 |
20100129544 | Polymer-Based Ceramic Coatings for Protecting Surfaces Against Fluoride Ions During a Cleaning Process - A process for the gentle cleaning of partially corroded or oxidized surfaces with fluoride ions is provided. The parts of the surface which are not corroded or oxidized are coated with polymer-based ceramics before the start of the cleaning process. The coating process includes applying a precursor of the polymer-based ceramic and then ceramicizing the precursor. | 05-27-2010 |
20100212541 | Material Composition for Producing a Coating for a Component made from a Metallic Base Material, and Coated Metallic Component - The invention relates to a material composition that is used for producing a coating for a component, especially a turbine component, which is made of a metallic basic material, i.e. a metal or a metal alloy. Said material composition comprises a matrix material for forming a basic coating matrix and at least one filler for adjusting desired coating proportions or coating characteristics. The matrix material can be provided especially with basic glass ceramic properties. The inventive material composition is characterized in that the matrix material and/or the filler contains nanoparticles | 08-26-2010 |
20110259363 | PROCESS FOR REMOVING A COATING FROM SURFACES OF COMPONENTS USING ONLY HYDROCHLORIC ACID - The removal of a coating from components after they have been used is often achieved using various acid baths and salt melts. A coating removal process that includes only using hydrochloric acid is provided. The duration of the process in which the coating is treated with the hydrochloric acids has a duration of between 2 and 2.5 hours. The process includes treated the coating with the hydrochloric acid at least twice. | 10-27-2011 |
20140234662 | LAYER SYSTEM HAVING A TWO-PLY METAL LAYER - Known protective layers having high Cr content and additional silicon form brittle phases, which additionally become brittle under the effect of carbon during use. The protective layer according to the invention comprises a two-part metal layer, which contains tantalum on the outside. | 08-21-2014 |
20140342186 | LAYER SYSTEM WITH DOUBLE MCRALX METALLIC LAYER - Known protective coatings with a high Cr-content and silicon as an additive have brittle phases which become additionally brittle under the influence of carbon during use. The protective coating herein has a double metallic layer that only contains tantalum on the outside contents of the layers. | 11-20-2014 |
