Abstract:
PROBLEM TO BE SOLVED: To provide a heat insulating layered structure which is not only excellent in heat insulation, but also inseparable between each layer as a single unit of whole layered structure, and provided with a long life of its heat insulation coating, especially of its exterior ceramic layer. SOLUTION: The heat insulation coating for a layered structure (1) of the invention is composed of; a metal adhesive layer (7), an interior ceramic layer (10) and an exterior ceramic layer (13). The metal adhesive layer consists of specific metals, such as cobalt and chromium, and the exterior ceramic layer consists of a specific gadolinium-zirconium oxide. A structural member with this coating can serve for such uses as aircraft, gas turbine, steam turbine, or compressor. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
Heat-insulating layered systems should have a long service life in addition to excellent heat-insulating properties. The inventive layered system (1) consists of an external ceramic layer (13) that has a mixed crystal consisting of gadolinium zirconate and gadolinium hafnate.

Abstract:
The invention relates to a coating system (2) for a component (1) which comprises a porous layer (3) and an abradable layer (4) on the porous layer (3). Further the invention relates to an assembly of two components (1) which are relatively movable to each other and form a gap in between. One component (1) is provided with a coating system (2) and the other component (1) is in sliding contact with the coating system (2).
Abstract:
A turbine blade has a blade tip, a cooling structure with cooling channels which are designed to have cooling fluid passed through them in order to cool the turbine blade during operation, an end section at a lower level than that of the blade tip, and an outer wall section extending up to the blade tip. The cooling structure is formed between the end section and the blade tip. A method produces a cooling structure of this type.

Procedimiento para registrar cambios microestructurales de una pieza de construcción (1), especialmente de un sistema de capas (1), midiendo dos veces o, especialmente múltiples veces al menos un parámetro de material de la pieza de construcción (1), asimismo es utilizado un método de medición para la determinación de un parámetro de material, seleccionado del grupo de capacidad eléctrica, conductibilidad térmica, capacidad térmica específica, coeficiente Peltier, susceptibilidad magnética, ferroelectricidad, piroelectricidad, ultrasonido o prueba mecánica con indentador.
Abstract:
Method for monitoring degradation of a layer system caused by thermal and mechanical overloading. According to the method electrical, mechanical and or material parameters of the layer system are monitored over time by repeated measurement and comparison. An example of the method is monitoring a ceramic thermal insulation layer (10) in which pores (13) provide an effective thermal shock behavior. During use in a turbine the pores are sintered with a resultant reduction in the pore size (16). Thus to monitor degradation, pore size is measured over time.
