Device for protection of components with combustible titanium alloy before titanium fires and processes for their preparation

The present invention allows the use of titanium-based materials in the gas turbine, especially in the engine and in particular in the compressor construction by providing an apparatus is provided that the claimed by titanium fire and / or FODS components (vanes, vane stages, rotor blades, blade stages) by means of at least protects two layers comprising the layer system, which is located on the surface to be protected components and is firmly connected thereto, possibly with the aid of an adhesion-promoting layer. The outermost layer is ceramic, the metallic nature underlying. Possibly. can follow, in which ceramic and metallic layers alternate with each other more layers. Moreover, a method for manufacturing the device according to the invention is provided. By the at least partial use of titanium alloys, in particular for guide vanes of gas turbines, the invention enables a significant weight reduction of compressors by may be omitted established in accordance with the prior art nickel or steel-based materials in favor of lighter titanium alloys.
