摘要： The invention relates to a film cooling hole (20) of gas turbine components to be cooled, having an inflow section (26) with a constant flow area, to which a diffuser section (28) with a variable flow area is connected. The aim of the invention is to provide a particularly efficient film cooling. To this end, the diffuser region (26) is simply widened in the direction perpendicular to the flow direction of the hotter medium M

摘要： In order to obtain epitaxial growth according to state of the art, a plurality of strips often need to be regularly produced on a plane in order to form a repairing area. This leads to an overlapping and incorrect orientation of crystalline structures. According to the inventive method, the strip is wide enough to prevent an overlapping since the width of the contour is adapted to the area which is to be repaired.

摘要： The invention relates to a method for testing a component (5), whereby subsurface corrosion regions (9) of oxidised carbides or of the subsurface sulphidised base material are determined by means of an eddy current measurement. In this way, the gas turbine blades can be ground or rejected especially before a costly cleaning and coating process carried out thereon.

摘要： A method for processing a cooling hole on a workpiece with laser. The cooling hole (10) includes a shaped hole section (11). The method comprises the following steps: emitting a first laser pulse to a rough processing part in the position of the shaped hole section to be processed on the workpiece (20) according to the geometrical parameters of the shaped hole section so as to remove the material of the workpiece on the rough machining part (11A) and finish the rough processing of the shaped hole section; emitting a second laser pulse to the processing allowance part beyond the rough processing part of the shaped hole section to be processed according to the geometrical parameters of the shaped hole section so as to remove the material allowance of the workpiece on the processing allowance part (11B) and finish the finish processing of the shaped hole section. The energy of the first laser pulse is larger than that of the second laser pulse. Also disclosed are a device for processing a cooling hole on a workpiece with laser, a system for processing a cooling hole on a workpiece and a machine readable storage medium.

摘要： The invention relates to a method for producing through-holes (7) in a wall (3) of a component (1), by means of laser radiation, said wall delimiting a cavity (2) in which a protection agent (5) is provided that can be liquefied when heated. According to said method, through-holes (7) are successively produced in the wall (3) of the component (1) in a plurality of defined points, two directly subsequent through-holes (7) being produced such that a through-hole (7) is produced in a predetermined point and the next through-hole (7) is produced in an additional point which is further away from the predetermined point than at least two, in particular three or more omitted points that are closer to the predetermined point, and/or are produced such that a through-hole (7) is produced in a predetermined point and the next through-hole (7) is produced an additional point. At least one point which lies between the predetermined and the additional point is omitted, in particular two or more points which lie between the predetermined point and the additional point are omitted.

摘要： With internal coating methods there is often the problem that an external surface of the hollow component that is to be coated also gets coated at the same time. The device (1) according to the invention consists in that the external surface (13) of the component (2) is protected by a tubular element (4), which abuts in the region (32) of the outlet opening (7) of the hollow component (2), when the hollow space (10) of the component (2) is being coated.

摘要： The invention relates to a method for laser welding a workpiece (1) along a welding line (20). A laser beam (13) is guided along the welding line (20) by moving an optical deflector unit (17). High movement speeds can be obtained using only a limited amount of machinery. The invention is particularly suitable for welding closure pins and casting induced openings (7) of gas turbine blades (1).
