METHOD FOR PRODUCING A GAS TURBINE COMPONENT

A method for producing a gas turbine component, which comes into frictional contact with a friction partner, includes: providing a base body produced from a superalloy; applying a first metal coating to a surface of the base body facing the at least one friction partner in the mounted state, wherein...

Beschreibung
Zusammenfassung:	A method for producing a gas turbine component, which comes into frictional contact with a friction partner, includes: providing a base body produced from a superalloy; applying a first metal coating to a surface of the base body facing the at least one friction partner in the mounted state, wherein an additive production method using a first metal powder is used to apply the first metal coating; and applying a second metal coating to the first metal coating, wherein an additive production method using a second metal powder and a pulverulent pore-forming agent is used to apply the second metal coating and, by adding the pore-forming agent, the porosity of the second metal coating is set such that it is greater than the porosity of the first metal coating, and the volume flows of the introduced metal powder and the introduced pulverulent pore-forming agent are set or controlled separately.
