Description
- The present invention relates to a component, in particular a gas turbine component such as a turbine rotor blade, having a plating, in particular a blade tip plating, as recited in the preamble of Claim 1.
- Turbomachines, such as gas turbines, generally have a plurality of rotating rotor blades and a plurality of stationary guide blades, the rotor blades rotating together with a rotor and the rotor blades and guide blades being enclosed in a stationary housing. In order to improve performance, it is important to optimize all components and subsystems, including what are known as sealing systems.
- In turbomachines, a particular problem is the maintenance of a minimum gap between the rotating rotor blades and the stationary housing of a high-pressure compressor. This is because high-pressure compressors exhibit the highest absolute temperatures and temperature gradients, which makes it difficult to maintain the gap between the rotating rotor blades and the stationary housing. Inter alia, another reason for this is that compressor rotor blades do not have shrouds as are used in turbine rotor blades.
- As just mentioned, rotor blades in a compressor do not have shrouds. Therefore, ends or tips of the rotor blades are exposed to direct frictional contact with the stationary housing, in what is called blade rubbing. Such rubbing of the tips of the rotor blades in the housing is caused by manufacturing tolerances during the setting of a minimum radial gap. Because the frictional contact of the tips of the rotor blades wears material away from them, an undesired enlargement of the gap can result around the entire periphery of the housing and rotor. In order to avoid this, it is known from the prior art to plate the ends or tips of the rotor blades with a hard coating or with abrasive particles. Two different types of blade tip platings are known from the prior art, namely, on the one hand, platings of a ceramic material or, on the other hand, platings of abrasive particles. The present invention relates to a plating, in particular a blade tip plating, of a component, in particular a gas turbine rotor blade, with abrasive particles.
- U.S. Pat. No. 6,194,086 B1 discloses a rotor blade of a gas turbine having a blade tip plating in which the blade tip plating comprises a cover layer that is made of abrasive particles embedded in a metallic matrix material. The cover layer made up of the abrasive particles embedded in the metallic matrix material is applied onto the tip of a rotor blade that is to be plated with the interposition of a metallic bonding layer. The metallic bonding layer is fashioned as a LPPS layer, and is accordingly applied to the component using low-pressure plasma spraying. The disadvantage of such LPPS bonding layers is that in particular at high operating temperatures of up to 1200° C. they have low mechanical adhesion to the blade tip, so that during operation the blade tip plating can flake off.
- Against this background, the present invention is based on the problem of creating a new type of component having a plating. This problem is solved by a component as recited in Claim 1. According to the present invention, the metallic bonding layer is fashioned as a bonding layer that is applied to the component using high-speed flame spraying, the metallic matrix material of the cover layer being galvanically deposited.
- According to the present invention, the bonding layer is applied to the component using high-speed flame spraying. In this way, the plating adheres to the component better than is the case given the use of LPPS bonding layers. The blade tip plating of the component accordingly has better mechanical bonding, in particular at high operating temperatures.
- Preferred further developments of the present invention result from the subclaims and from the following description. Exemplary embodiments of the present invention are explained in more detail on the basis of the drawing, without being limited thereto.
