摘要:
A cladding (22) for a wall (12) includes a barrier layer (24) that can be deformed by the action of a polymer actuator (14). According to the invention, a contact surface (A) of the cladding lies completely against the wall, at least in the non-deformed state, stabilizing the intrinsically elastic wall cladding. For example, the wall cladding can be fixed to the wall (12) in the form of lamellae (22), at respective points, in such a way that the activation of the polymer actuator (14) causes the lamellae (22) to bend, thus permitting, for example, a layer (25) of ice to be detached from the cladding. Alternatively, the cladding can also be configured from a membrane actuator, which is fixed at points, or by its entire surface to the wall (12).

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.

摘要:
Inner coatings according to the prior art often do not produce a uniform coating. The method according to the invention for the coating of a component with a cavity is characterized in that a coating material is mixed with a carrier material and introduced into the cavity, the carrier material decomposing at the evaporating temperature of the coating material, or has already decomposed, and the coating material being deposited from the gas phase on the component.

The invention relates to a lamp, particularly a high-pressure discharge lamp, comprising a base (24), whereby an upper electric connection (28b) is contacted by a return conductor (27) running along a lamp body (14), and to a method for producing a lamp of this type. According to the invention, the return conductor (27) is provided by a conducting layer (17), which is applied using vacuum technology, in particular, sputtering and which is directly located on the lamp body (14). This results in reducing manufacturing costs associated with the mounting of an isolated return conductor (27) running parallel to the lamp body (14). In addition, the lamp produced in the aforementioned manner reliably functions by virtue of the fact that the conducting layer (17) is not affected by vibrations. This lamp can be used, for example, for headlamps of a motor vehicle.
摘要:
In a cold gas spraying method, a gas jet (15) into which particles (19) are introduced is generated with the aid of a cold gas spray gun (20). The kinetic energy of the particles (19) results in a layer being formed on a substrate (13). The substrate is provided with a structured texture (24) which is transferred to the layer (20) that is formed. The method makes it advantageously possible to produce a high-temperature superconducting layer on the substrate (13) by selecting an appropriate particle (19) composition. The process can be additionally supported using a heating device (25) in a subsequent thermal treatment step.
摘要:
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.
