A plug for brazing in a through-hole and for sealing a through-hole in a substrate of a gas turbine component. The plug has at least one elongate part and a head, wherein the head is made wider in cross section than the elongate part. The elongate part has a cross section which becomes smaller towards its end face along its longitudinal axis, wherein the elongate part has a peripheral region on its end face, wherein the peripheral region of the elongate part has a brazing filler metal. The head has a peripheral region on its end face, wherein the peripheral region of the head has a brazing filler metal, and the remaining and largest part of the elongate part and of the head has a mixture of brazing filler metal and a substrate material.

Brazing plug, component of a gas turbine and method

A method of manufacturing a hard-to-weld material by a beam-assisted additive manufacturing process is presented. The method includes depositing a first layer for the material onto the substrate, the first layer including a major fraction of a base material for the component and a minor fraction of a solder, depositing a second layer of the base material for the component and a thermal treatment of the layer arrangement. The thermal treatment includes a first thermal cycle at a first temperature above 1200&#xb0; C. for a duration of more than 3 hours, a subsequent second thermal cycle at a second temperature above 1000&#xb0; C. for more than 2 hours, and a subsequent third thermal cycle and a third temperature above 700&#xb0; C. for more than 12 hours. A manufactured component is also presented.

Manufacturing method for hard-to-weld materials

A method for applying a wear protection layer to a continuous flow machine component which has a base material comprising titanium is provided. The method includes the following steps: mixing a solder which comprises an alloy comprising titanium and particles which are distributed in the alloy and have a reaction agent; applying the solder to predetermined points of the continuous flow machine component; introducing a heat volume into the solder and the continuous flow machine component so that the alloy becomes liquid and the reaction agent changes through diffusion processes with the solder and undergoes a chemical reaction with the alloy, forming a hard aggregate; and cooling the solder so that the alloy becomes solid.

Method for applying a wear-resistant layer to a turbomachine component

A method in which no voids occur during the soldering processes is provided. A component with a soldering material is heated using a first temperature plateau for a first time duration such that the solder material is completely melted. Each subsequent heating is at a temperature plateau with a temperature that is lower than a temperature of the previous plateau.

Method for soldering with a multistep temperature profile

In soldering processes according to prior art, there is often an insufficient tie-up to a substrate of a component. A method in which no voids occur during the soldering processes is provided. A temperature pattern is proposed according to the method in which the temperature is lowered successively during the soldering operation.
