WALL DEPOSITION

A method of forming a wall structure on a substrate comprises depositing, by additive-layer, powder-fed, laser-weld deposition apparatus, a plurality of material layers overlying one another on the substrate to form the wall structure. Each material layer of the plurality of material layers has (a)...

Zusammenfassung:	A method of forming a wall structure on a substrate comprises depositing, by additive-layer, powder-fed, laser-weld deposition apparatus, a plurality of material layers overlying one another on the substrate to form the wall structure. Each material layer of the plurality of material layers has (a) a layer thickness, measured in a direction locally perpendicular to a profile of the substrate, of no greater than about 350 µm and (b) a layer width, measured in a direction locally parallel to the profile of the substrate, of no greater than about 1200 µm.
