摘要： The invention relates to a laser-plasma hybrid welding method, whereby in order to weld workpieces, a laser beam (10) and a plasma beam (11) are brought together in the process area located near the workpieces. According to the invention, the free microwave-induced plasma beam (11) is produced using the following method steps: generating microwaves in a high-frequency microwave source; guiding the microwaves in a waveguide (1); introducing a process gas into a microwave-transparent tube (2), which has a gas inlet opening (14) and a gas outlet opening (15) at a pressure p >/= 1 bar, whereby the process gas is introduced into the microwave-transparent tube (2) via the gas inlet opening (14) so that it has a tangential flow component; producing a plasma (12) inside the microwave-transparent tube (2) by igniting the process gas without the use of electrodes; producing a plasma beam (11) by introducing the plasma (12) into the working space (16) via a metallic nozzle (1) located at the gas outlet opening (15) of the tube (2).

摘要： The invention relates to a wear-resistant layer, particularly an erosion-resistant layer for components of a gas turbine. Said wear-resistant layer (13) is applied to a surface (14) of a fluidically stressed component (10), which is to be protected. The inventive wear-resistant layer (13) comprises an at least double-layered structure. A first layer (15) is applied to the surface (14) of the component (10), which is to be protected, and is provided with a material composition that is adapted to the material composition of the component (10) while a second layer (16) forms an outer coating.

摘要： The invention relates to a method for purifying gases, particularly for purifying gases (RG) polluted with environmental pollutants by using plasma discharge. According to the invention, the gas (RG) to be purified is guided through a thermal plasma (7) that is produced by igniting a process gas (P) without using electrodes so that the pollutants contained in the gas (G) to be purified are converted by the thermal plasma (7) into environmentally neutral, completely oxidized substances.
