Abstract
(EN)
A hybrid three-layer system is presented. The hybrid three-layer system includes a two-layer composite system and an additively manufactured third layer comprising a lattice structure. The composite layer system includes a metallic substrate, a structured surface, and a thermal protection system. The structured surface may be additively manufactured onto the metallic substrate and includes structured surface features formed to project above the metallic substrate. Each of the structured surface features are separated from adjacent structured surface features by grooves. The thermal protection coating may be thermally sprayed onto the structured surface and is bonded to each of the structured surface features. The lattice structure is in contact with a surface of the metallic substrate of the composite layer system.

L'invention concerne un système hybride à trois couches. Le système hybride à trois couches comprend un système composite à deux couches et une troisième couche fabriqués de manière additive comprenant une structure en treillis. Le système composite en couches comprend un substrat métallique, une surface structurée et un système de protection thermique. La surface structurée peut être fabriquée de manière additive sur le substrat métallique et comprend des éléments de surface structurés formés pour faire saillie au-dessus du substrat métallique. Chacun des éléments de surface structurée est séparé d'éléments de surface structurée adjacents par des rainures. Le revêtement de protection thermique peut être pulvérisé thermiquement sur la surface structurée et est lié à chacun des éléments de surface structurées. La structure en treillis est en contact avec une surface du substrat métallique du système composite en couches.
