In the field of gas turbines, this enables now targeted repair and the realization of novel component designs by means of laser-based processes such as direct laser deposition or selective laser melting. In the case of ceramic materials, the necessary high processing temperatures and the lack of ductility of ceramics often lead to high local stresses and crack formation even in relatively small structures. This makes it difficult to build defect-free components and still restricts the range of applications.In the field of gas turbine applications, however, there are microstructure requirements, particularly for ceramic thermal barrier coatings, which can in principle be met by laser-based additive manufacturing. Due to the high demands on the thermal shock resistance of the coatings, the presence of porous areas or segmentation cracks, for example, can not only be tolerated, but supports the function and lifetime of the coatings. In this contribution, a novel laser cladding process (Clad2Z) for the deposition of columnar structures is presented, which can be used for localized fabrication and repair of thermal barrier coatings [1]. The stability and durability of the so-prepared TBCs were investigated under realistic gradient conditions in burner rig tests. The durability and failure mode qualify the coatings as at least equivalent to conventional TBC systems.[1] “Additive manufacturing of columnar thermal barrier coatings by laser cladding of ceramic feedstock” (DOI: 10.1002/admt.202200098) 001025662 536__ $$0G:(DE-HGF)POF4-1241$$a1241 - Gas turbines (POF4-124)$$cPOF4-124$$fPOF IV$$x0 001025662 7001_ $$0P:(DE-Juel1)171660$$aDommann, Christoph$$b1$$ufzj 001025662 7001_ $$0P:(DE-Juel1)129670$$aVassen, Robert$$b2$$ufzj 001025662 7001_ $$0P:(DE-Juel1)162228$$aGuillon, Olivier$$b3$$ufzj 001025662 8564_ $$uhttps://etn.global/wp-content/uploads/2023/10/IGTC-23-Abstract-Collection.pdf 001025662 909CO $$ooai:juser.fz-juelich.de:1025662$$pVDB 001025662 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129630$$aForschungszentrum Jülich$$b0$$kFZJ 001025662 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)171660$$aForschungszentrum Jülich$$b1$$kFZJ 001025662 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129670$$aForschungszentrum Jülich$$b2$$kFZJ 001025662 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)162228$$aForschungszentrum Jülich$$b3$$kFZJ 001025662 9131_ $$0G:(DE-HGF)POF4-124$$1G:(DE-HGF)POF4-120$$2G:(DE-HGF)POF4-100$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-1241$$aDE-HGF$$bForschungsbereich Energie$$lMaterialien und Technologien für die Energiewende (MTET)$$vHochtemperaturtechnologien$$x0 001025662 9141_ $$y2024 001025662 920__ $$lyes 001025662 9201_ $$0I:(DE-Juel1)IEK-1-20101013$$kIEK-1$$lWerkstoffsynthese und Herstellungsverfahren$$x0 001025662 980__ $$acontrib 001025662 980__ $$aVDB 001025662 980__ $$acontb 001025662 980__ $$aI:(DE-Juel1)IEK-1-20101013 001025662 980__ $$aUNRESTRICTED 001025662 981__ $$aI:(DE-Juel1)IMD-2-20101013
