Definitions
- the invention relates to a joining method and a gas turbine component produced by the joining method.
- Sintering method with which a component made of a powdery starting material can be finished.
- this starting material is placed in a mold, placed under high pressure and a continuous or pulsed current
- the spark plasma sintering method (omitting a form) can also be used for joining macroscopic components.
- the aim is to achieve the strongest possible connection of the components joined in this way.
- the invention therefore sets itself the task of specifying an improved joining method for joining two components.
- the invention therefore introduces a method for connecting a first component to a second component.
- the method has at least the following steps:
- the laser remelting is a method in which the surface-surface of a workpiece with a laser irradiated and melted on ⁇ .
- the laser is moved over the surface, so that the surface is melted successively.
- the laser working point leaves a respective point, it solidifies again, wherein the solidifying melt pool has properties deviating from the unprocessed parts of the workpiece.
- an additional step of laser remelting of the joining surface of the second component is carried out prior to placement.
- the area around the joining surface of the second component as described above is advantageous bear ⁇ beitet before the spark plasma sintering method is used to join the two components.
- Crystal orientation of the first component is particularly preferred by the laser remelting aligned with a crystal of ⁇ direction of the second component, so that after the step of placing the first and second components have Wenig ⁇ least approximately the same crystal orientations.
- the fact observed during test procedures by the inventors is exploited that an epitaxial growth can be observed in the region of the joining zone, ie a crystal orientation of one of the components in the joining zone and the joining partner is adopted.
- a large-area disturbance of the internal structure of the component joined in this way along the joining surfaces can be avoided.
- the undisturbed continuation of the crystal alignments on both sides of the joining zone causes a particularly strong connection of the two output components.
- the crystals grow in the direction of the largest temperature gradient, usually from the surface heated by the laser, to the interior of the workpiece.
- the method according to the invention is particularly suitable for components made of difficult-to-weld metals (for example
- At least one of the first and second members preferably includes a nickel-base superalloy or is made of the nickel-base superalloy.
- a dendritic crystal structure can be generated.
- the dendrites are usually arranged perpendicular or approximately perpendicular to the laser-melted joining surface.
- the joining surface is preferably laser remelted to a depth of at least 50 micrometers in order to allow a sufficiently wide joining zone.
- the depth amounts to be ⁇ vorzugt less than one millimeter, since a greater remelt depth is difficult to achieve and would bring no further advantages that would justify the increased processing time.
- the first component can be applied at a pressure of 1 to 40 megapascals during the Spark Plasma Sintering process second component to be pressed. Also, the first and the second component during the spark plasma sintering procedural ⁇ proceedings to a temperature of 1000 to 1200 degrees Celsius can he get too hot ⁇ . Suitable heating and cooling rates may be in the range of 20 to 200 Kelvin per minute. During the spark plasma sintering process, a GE ⁇ Pulster or a continuous stream through the first and the second component can be guided.
- a second aspect of the invention relates to a gas turbine component made according to the method of the invention.
- An example of such a gas turbine component is a gas turbine blade .
- the procedural ⁇ ren invention can be nenkomponenten for the production of other machines and use workpieces however.
- FIGURE shows a cross-section through a workpiece 1, which consists of a nickel-base superalloy and whose upper surface 2 lying in the image above and extending into the depth of the image has been remelted by a laser remelting process.
- the laser-remelted zone 3 is delimited by a curved dashed line from the unchanged part 4 of the workpiece.
- the laser was directed from a direction of incidence ⁇ 5 on the surface 2 of the workpiece 1.
- a laser power of, for example, 75 to 100 watts can be used when the laser is at a speed of 40 to 60 milli-seconds. meter per minute over the surface of the workpiece. This results in a melt pool depth of about 200 to 300 microns. In the present case, work was carried out over a width of a few millimeters.
- parameters deviating from these specifications for laser remelting can be determined by the person skilled in the art.
