摘要:
In a method for producing a starting material (M, N, N′) for the production of a wear layer (420), a coating (40) with a composition which corresponds to that of the wear layer (420) which is to be produced is chemically undissolved from its substrate (30) and is detached as a solid body, and that the starting material (M, N, N′) is formed by the layer material (60) of the detached coating (40).
摘要:
There is described a substrate with a coating; the coating contains a coating matrix in whose matrix structure multilayered and/or encapsulated nanoparticles are arranged and release a dye when a limit temperature is exceeded the first time and/or trigger a color reaction which causes the color of the coating to change irreversibly.

A system and method for planning outages for a power generation installation comprising a gas turbine power plant. The system and method utilizes a computer to receive requests from users to create maintenance plans for the power plant by generating templates, applying the templates to a database containing gas turbine data for the power generation installation; and receiving data from users to create maintenance package plans. Users can select either modular or turnkey maintenance plans. Modular maintenance package options enable a user to specifically select and obtain price quote information for parts and technicians who perform the maintenance tasks, and to specify particular shift options for the technicians.
摘要:
The invention relates to a material composition that is used for producing a coating for a component, especially a turbine component, which is made of a metallic basic material, i.e. a metal or a metal alloy. Said material composition comprises a matrix material for forming a basic coating matrix and at least one filler for adjusting desired coating proportions or coating characteristics. The matrix material can be provided especially with basic glass ceramic properties. The inventive material composition is characterized in that the matrix material and/or the filler contains nanoparticles

The cold spraying process according to the invention uses cold gas streams whose properties (temperature (T), particle density (ρ), pressure (p), particle velocity (v)) are variably changed such that they can be adapted to the desired properties of the coatings.
摘要:
A method of repairing a component, in particular a gas turbine component, which is produced from a base material with an oriented microstructure, comprises the steps of: cleaning the repair site, filling the repair site with a filling material corresponding to the composition of the base material, carrying out a heat treatment in the region of the filled repair site, wherein the filling material has micro- and/or nano-scale particles, during the filling of the repair site measures which prevent the oxidation of the filling material are taken, an the temperatures and holding times of the heat treatment are set appropriately for the composition of the filling material and of the base material of the component in such a way that an epitaxial attachment of the filling material to the surrounding bas material takes place.

摘要:
A powder can be produced by immersing microparticles (2) in a first solution (4) which contains coupling molecules (5), and then in a second solution (10) which contains the nanoparticles (12), thereby producing microparticles (2) with nanoparticles (12) attached thereto. The particles form powder particles (14) which allow nanoparticles (12) that are smaller than approximately 5 [mu] to be applied to a component by cold gas spraying.
摘要:
Short fibers in a solder or a welding material often do not have the desired strength. Fiber mats that are introduced onto a surface or into a recess of a metallic component are provided. In addition a process for applying material to a metallic component is provided. In the process, a first fiber mat and a second fiber mat are used.
