摘要： In a method for the cold-gas spraying of particles having different solidities and/or ductilities and in a cold-gas spraying device (11) suitable for use in with the method, in order to obtain a comparatively high proportion of particles (23) having higher solidity and/or smaller ductility in comparison to the other particles (22), these particles are fed into an area (21) of the stagnation chamber (15) of the cold-gas spraying device which is very distant from the nozzle (14). Advantageously, the particles (23) have to cover a longer course through the stagnation chamber and are thus preheated. In this way, the deposition of these particles (23) on a substrate (25) is improved. Particularly metals having a transition temperature ranging between brittle and ductile behavior can be provided with ductile properties by the preheating process, thereby simplifying the deposition process.

摘要： The invention relates to a component that is suitable for use as a sliding bearing. The invention further relates to a method for the production of said component. The design of the component according to the invention provides a layer of a light metal material (13), which is provided with an oxide layer (15) containing pores (16) in the direction of the sliding surface (23) of the component. A hard material (18) is placed in the pores, which greatly increases the firmness of said layer region, thus creating the mechanical firmness for use as a sliding bearing. In order to counteract the tendency of said firm layer region to experience brittle failure, the oxide layer (15) is coated with a solid lubricant layer (20). Said solid lubricant layer comprises a metallic, ductile matrix (21), which distributes a force (F) acting at certain points over a larger surface region (b). In order to improve the sliding characteristics, particles of a solid lubricant (22) are simultaneously embedded in the solid lubricant layer (20).

摘要： A transport system for dry nanoparticles (18b). According to the invention, the nanoparticles (18b) are magnetized or electrically charged for transportation, a magnetic or electrical field is produced by a field generator (20a, 20) in the transport channel, and the nanoparticles (18b) migrate through the transport channel (12). The nanoparticles can be discharged through a discharge opening (13) which enables dosing to take place. In order to agglomerate the nanoparticles (18b) or to prevent attachment onto the inner wall (26), a coating (27) of the wall can be offset in oscillations by piezo electric actuators (28), the oscillations being transferred to the nanoparticles (18b). The dry nanoparticles can be handled in an advantageous manner due to the transport system, such that the dry nanoparticles need not be treated as a suspension.

摘要： A hard material layer having a relatively low frictional resistance, which can be produced by impregnating the layer with a lubricant. Zirconium oxynitride layer, which has zirconium-, nitrogen- and oxygen-containing phase, is used as a hard material layer. The presence of the phase in the zirconium oxynitride layer leads to a perceptible reduction of the layer frictional resistance, such that further processing steps can advantageously be saved on coating of substrates, such a impregnation. The coating (26) can, for example, be applied on a tool (27), which is appropriate for metal-cutting machining a work piece (28). With the low frictional resistance, a dry machining of the work piece (28) can be executed with the tool. Another application is the coating of highly stressed components of fuel injection valve.

摘要： 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. According to the inventive method, contaminated process gas is directed into an analysis chamber where a plasma is ignited and is analyzed using emission spectroscopy in order to monitor the process, particularly to determine the conditions for stopping the process. 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.
