Definitions
- the invention relates to a coating for a hot gas confronting component such as a boiler, a fuel cell, a melting furnace, a motor, an engine, a gas turbine blade and / or a Gasturbinenschaufei.
- a hot gas confronting component such as a boiler, a fuel cell, a melting furnace, a motor, an engine, a gas turbine blade and / or a Gasturbinenschaufei.
- Such a material meets a demanding property profile, in particular stability at high thermi ⁇ shear stress, compatibility with conventional TBC thermal barrier coatings, and the simplicity of the relationship between temperature and recognizable and / or measurable material composition concerns.
- TBC Thermal Barrier Coatings
- Melting furnace, engine, engine, gas turbine blade and / or gas turbine blade can be incorporated.
- the subject of the present invention is a thermally loadable coating of a ceramic material
- Ion-containing species in a kinetically single-stage reaction takes place, so that a direct relationship between the type of luminescence, ie the concentration of europium and / or samarium-3 + ions in the matrix and the temperature history of a component equipped with the coating can be produced and, for example, graphically displayed.
- the europium and / or samarium 3 + ions are present as incorrect occupancy of cation lattice sites.
- the coating comprises the particles containing europium and / or samarium 3+ ions in an amount of more than one mole percent.
- the luminescent particles in an amount of more than 5 mol%, and particularly preferred are the luminesce ⁇ the particles in an amount of more than 10 mol% in the Kera ⁇ mix prior to coating.
- the lu- mine ornamental particles can be readily incorporated in the ceramic coating, because the matrix material compatible with the material of Be ⁇ coating and / or crystallographically similar or even partially identical.
- the matrix is a so-called TBC Thermal Barrier Coating- loading coating material, in particular one of a yttrium aluminum oxide, for example a Y2AI 5 O 1 2 or walls ⁇ ren-oxidic ceramic material.
- Suitable TBC coatings are known, for example, from US Pat. No. 8,685,545, EP1915639 and / or WO2007 / 020170.
- the luminescent Eu3 + and / or Sm3 + ions can be incorporated well into a ceramic matrix, since they can occupy cation sites in different ceramic lattice structures from the ionic radius, without thereby causing a dissolution of the lattice structure.
- the europium and / or samarium 2+ and / or 3+ ions have already been successfully tested in an yttrium oxide, for example in an yttrium-aluminum oxide matrix.
- particles having a matrix of an yttrium oxide-containing ceramic with - for example - a melting point above 1300 ° C, a polyhedral morphology and / or a grain size in the range of 2 to 50ym were used.
- the europium and / or samarium 3+ ions are incorporated into the host lattice without destroying the morphology.
- the luminescent particles are used at least partially in the form of spherical particles.
- the oxidation of the europium and / or samarium 2+ ions into the europium and / or samarium 3+ ions is effected by the hot and oxygen-containing vapor, which distinctly luminesce favored.
- the disintegration time of the one luminescent species depends on only a single reaction, by which the luminescent cation in question is converted into its other luminescent species.
- the structure transforms the Eu 2+ in the Eu 3+ with at ⁇ Otherwise the same chemical environment and the same grid.
- the luminescence changes interpreting ⁇ Lich and the temperature is easily detectable.
- the temperature can be tracked via a spectroscopic method and / or via a reference table, so that the temperature history can be deduced directly from the concentration and type of luminescent species.
- the incorporation of the luminescent particles in the coating can take place in the production and / or as retrofitting, for example by spraying, coating, painting, etc. in a suitable binder system.
- the invention relates to a coating for a hot gas confronting component such as a boiler, a fuel cell, a melting furnace, a motor, an engine, a gas turbine blade and / or a Gasturbinenschaufei.
- the coating is characterized by having a temperature sensor in the form of a light-emitting coating, the light emission of which depends on the temperatures to which the coating is or has been exposed.
