20080277288 | Method For Removing A Coating From A Component - Method for removing coatings which have been applied to components such as turbine blades. After the end of the product life cycle of the turbine blades has been reached, these coatings can be removed to reuse the turbine blades after recoating. The coating, containing in particular chromium oxide compounds is removed via a stripping bath by adding alkanolamine compounds or salts containing such compounds as the inhibitor. These compounds advantageously prevent new chromium oxide compounds from being produced during the stripping of the turbine blades or the chromium oxide compounds present in the coating are removed effectively, so that the chromium oxide compounds cannot have an adverse influence on the removal rate of the stripping process. Advantageously reduced treatment times can thereby be achieved for the stripping process. By adding 2% triethanolamine, the treatment time in hydrochloric acid for example can be reduced to below one hour. | 11-13-2008 |

20090202732 | Method for Producing Ceramic Layers - The invention relates to a method for producing ceramic layers by spraying. A cold gas spraying method is used to produce polymer ceramics from pre-ceramic polymers. According to said method, a cold gas stream, to which particles of the pre-ceramic polymers are added via a conduit, is generated by a spray gun. The energy for creating a layer on a substrate is produced by injecting a powerful kinetic energy into the cold gas stream, thus preventing or significantly restricting the thermal heating of the cold gas stream. This permits the heat-sensitive pre-ceramic polymers to be spray-applied as a coating on a substrate using a cold gas spraying method. Polymer ceramics can thus be used in an economic method for the rapid production of layers with a relatively large thickness. The invention allows for example armoured layers, thermal protection layers and other functional layers to be produced. | 08-13-2009 |
20090223538 | Method for Cleaning a Workpiece With the Aid of Halogen Ions - The invention relates to a method for cleaning turbine blades, for example, in a cleaning chamber into which a process gas containing especially fluoride ions is introduced.

The spectrometric measurement can be evaluated in an evaluation unit, the cleaning process being stopped via signal line in case of a characteristic change of the spectrum. Also disclosed is a cleaning device comprising an analysis apparatus with a sample chamber and a plasma generator, an interface being provided for evaluating the result of the analysis. | 09-10-2009 |

20100068410 | Cold Gas Spraying Method - A method for coating a workpiece by cold gas spraying is carried out using a cold gas spray nozzle which generates a particle jet that is directed onto the surface. Additional energy is introduced into the layer that is being formed by way of an electromagnetic energy source, e.g. a laser, which the energy introduced into the particles by the cold gas spray nozzle also contributes to forming the layer. The cold spraying process can be used flexibly as a result of the additional activation by way of electromagnetic radiation. Moreover, layers having a complicated structure, e.g. strip conductors, can be created with the aid of the laser without further processing. A coating unit includes a generator for electromagnetic radiation in addition to the cold gas spray nozzle and is therefore suitable for carrying out the novel method. | 03-18-2010 |
