Abstract (en)
Thermal barrier coating system for a high Titanium content superalloy substrate and method for applying the substrate with the thermal barrier system A thermal barrier coating system for a high Titanium content superalloy substrate comprises a first bondcoat layer being applied to the substrate surface and adhering thereon, a second bondcoat layer being applied to the first bondcoat layer and adhering thereon, and a thermal barrier topcoat layer made of a ceramic material and being applied to the second bondcoat layer and adhering thereon in such a way that the surface of said substrate is protected from corrosion, oxidation and high temperature thermal exposure, wherein the first bondcoat layer and the second bondcoat layer are made of metal material alloys having similar compositions but different phase structures so that the combination of both bondcoat layers is to inhibit diffusion of Titanium from the substrate material into the second bondcoat layer surface beneath the topcoat layer and to keep bondcoat functions.
