Abstract (en)
[origin: EP2439379A2] Two components such as rotor (2) and stator (6) are relatively moved, such that entry of components in the layer system is performed. An adhesive layer is formed on any one of components. A protecting layer is formed on the adhesive layer. Another adhesive layer is formed on the protecting layer. A continuous layer which is softer than the protecting layer is formed on adhesive layer. The protecting and continuous layers are made of ceramic, alumina and zirconium oxide. An independent claim is included for method for manufacturing layer system.
