Abstract: An excellent abrasive blade tip is provided by a two-layer coating system consisting of a brazing solder coating and an NiCoCrAlY coating containing cBN (cubic Boron Nitride).

Abstract: A soldering method in which abrasive particles, in particular cubic boron nitride, are applied in a matrix composed of a solder material and are intended to have better adhesion in the matrix material. The particle which includes an abrasive particle, in particular of cubic boron nitride, is coated with a metal. A method for producing a layer on a substrate, wherein a solder material is applied as metallic matrix material such with particles, in particular solder material in the form of a soldering paste, a soldering tape, a solder powder, by an application method, in particular by a welding process or a thermal spraying process.

Abstract: A welding method using coated abrasive particles, coated abrasive particles, coating system and sealing system which uses particles, in which a hard material layer is applied around abrasive particles such as cubic boron nitride (cBN) and protects against oxidation during welding. The hard material compound in the coating may include a carbide, in particular titanium carbide. A sealing system is composed of stator and rotor blade having the layer system.

Abstract: The invention relates to a ceramic sealing system between a rotor blade (120) and a housing (I). A small porous zirconium oxide layer (II) on a turbine rotor blade, which zirconium oxide layer faces a ceramic layer system (15?, 15?) of higher porosity, achieves durable sealing systems. The housing (I?) has a metal substrate (7), a metal adhesion-promoting layer (10), and a thick, outer, ceramic layer (15?, 15?) based on zirconium oxide, in particular having a porosity 2?14%.

Abstract: A plasma spray nozzle is provided. Owing to their high degree of wear, previous plasma spray nozzles were not suitable for the coating of components for which long coating times were necessary. The coating times may be reduced considerably by the triple injection of powder into the inner channel through the plasma spray nozzle.
