20100098550 | Method for coating of a base body and also a workpiece - A method for the coating of a base body is proposed, in which a layer of a platinum modified aluminide of the kind PtMAl is produced on the base body wherein M designates the metals iron (Fe) or nickel (Ni) or cobalt (Co) or combinations of these metals, wherein the layer is produced by means of a physical deposition out of the gas phase (PVD), wherein at least the two components aluminium (Al) and metal M are physically deposited out of the vapour phase, with the deposition being carried out at a process pressure of at least 0.1 mbar, preferably of at least 0.4 mbar and especially between 0.4 mbar and 0.6 mbar. A workpiece is further proposed, in particular a turbine blade, with a base body on which a layer is applied which is produced using a method of this kind. | 2010-04-22 |
20100098551 | METHOD AND DEVICE FOR COATING COMPONENTS OF A GAS TURBINE - The present invention relates to a method for coating components of a gas turbine, in particular for producing a wear-resistant, temperature, oxidation and/or corrosion-resistant protective coating on the component, wherein the protective coating is made of at least one solder film or slurry coating, which is connected to the corresponding region of the component by means of an inductive high-temperature soldering method. The bonded connection between the component and the solder film or slurry coating disposed on the component is achieved by locally heating the component in the region of the solder film or slurry coating to be applied, and simultaneously heating the solder film or slurry coating by means of thermal energy generated and emitted by at least one induction amplifier, wherein the induction amplifier is disposed between the inductor and the component in the region of the solder film or slurry coating. The invention further relates to a device for coating components of a gas turbine, in particular for producing a wear-resistant, temperature, oxidation and/or corrosion-resistant protective coating on the component, using at least one inductor for carrying out an inductive high-temperature soldering method for heating and bonding at least one component to at least one solder film or slurry coating forming the protective coating, wherein according to the invention at least one induction amplifier is disposed in the region of the solder film or slurry coating between the inductor and the component having the solder film or slurry coating. | 2010-04-22 |
20100098552 | BLADE ROOT EXTENDER FOR A WIND TURBINE - The field of the invention is a blade root extender for a wind turbine assembled between the blade root and a hub fixed to the wind turbine's nacelle. The extender is made up of a hollow, corrugated cylinder, one or two terminal flanges with holes for some preloaded stud bolts that apply pressure to the blade root extender. | 2010-04-22 |
