High temperature capable additively manufactured turbine component design

A hybrid three-layer system, comprising:

• a two-layer composite layer system, comprising:
• a structured surface additively manufactured onto a metallic substrate and including structured surface features formed to project above the metallic substrate, each of the structured surface features separated from adjacent structured surface features by grooves, and
• a thermal protection coating thermally sprayed onto the structured surface and bonded to each of the structured surface features;
• and
• an additively manufactured third layer comprising a lattice structure in contact with a surface of the metallic substrate of the composite layer system
• wherein the hybrid three-layer system is at least a portion of a gas turbine component exposed to a hot combustion gas;
• wherein the gas turbine component comprises an airfoil;
• wherein the metallic substrate includes a plurality of wavy cooling channels for the passage of a cooling air;
• wherein a pressure side of the airfoil includes a first plurality of wavy cooling channels and a suction side of the airfoil includes a second plurality of wavy cooling channels, and wherein the first plurality of wavy channels include a higher amplitude than the second plurality of wavy channels.
