<p>The present invention enables the use of titanium-based materials in gas turbine construction, especially in engine, and particularly in compressor, construction, in that a device is provided, which protects the components (g uide vanes, guide vane steps, rotating vanes, rotating vane steps) stressed by the titanium fire and/or FOD by means of a layer system comprising at lea st two layers, wherein the system is located on the surface of the component s to be protected and is firmly connected thereto, optionally with the aid o f an adhesive layer. The outer layer is of ceramic, and the layer beneath th e same is metal. Optionally, further layers may follow, wherein ceramic and metal layers alternate each other. The invention further provides a method f or the production of the device according to the invention. By means of the at least partial use of titanium alloys, particularly for the guide vanes of gas turbines, the invention enables a significant weight reduction of compr essors in that the nickel or steel-based materials utilized according to sta te of the art can be omitted in favor of lighter titanium alloys.</p> |
