Definitions
- the present invention relates to an apparatus for use in a method for the galvanic production of a hard material particles having protective layer on a component of a turbomachine, in particular a blade tip armor of a blade tip of a rotor blade.
- the invention further relates to a method for the galvanic production of a hard material particles having protective layer on a component of a turbomachine, in particular a blade tip armor of a blade tip of a rotor blade. 5
- the component surfaces are increasingly being provided with different coatings. This results in an improved aerodynamics in the engine, higher possible combustion temperatures and higher possible mechanical stresses of the individual components.
- the efficiency of the turbomachine is co-determined, in particular, by the rotor gap between the tips of the rotor blades and the wall of the rotor housing facing the rotor or the rotor blades.
- a so-called air seal is used, wherein the air seal defines so-called inlet linings on the inside of the housing and correspondingly hard surfaces on the blade tips.
- the application of a so-called blade tip armor reduces the wear on the blade tip during so-called running into the inlet lining significantly.
- the galvanic application of abrasive particles by galvanizing is known. Corresponding methods are described in US-A-5665217, US-A-5437724 and US-A-5074970. It will be used to coat the
- the hard material particles are embedded in the galvanically applied metallic matrix layer.
- a disadvantage of the known method and devices is that they are relatively complicated, since, inter alia, structurally complex devices are used for the galvanizing process.
- very high amounts of hard material particles are used to achieve the desired concentrations on the blade tips.
- Hard-material particles, such as, for example, hard-material particles of (cubic) boron nitride are very expensive, so that the use of the known methods is altogether very expensive.
- the receiving device is designed such that it can be detachably attached to an opening above and around a region of the component to be coated. By attaching the receiving device over or around the region of the component to be coated, a defined amount of hard material particles for the coating can be provided.
- the opening of the receiving device is surrounded by a flexible seal.
- the seal is laminated in the edge of the opening. Due to the design of a flexible seal at the edge of the opening of the receiving device, it can be securely attached to the component to be coated, for example a blade tip of a rotor, without further ado. The formation of a seal also ensures that the hard material particles are applied only in the actual areas of the component to be coated.
- the receiving device is connected in the region of its opening with a top base plate, such that the opening corresponds to an opening in the top base plate and the top base plate is releasably secured to a cover.
- the cover 5 at least one mold opening for receiving the areas to be coated of the component, wherein the opening of the top base plate is positioned with the opening of the Aufhahmevorraum over these areas.
- a design of the device ensures a secure and defined recording of the areas of the component to be coated in the cover and a corresponding positioning of the hard material particles ent-0 holding recording device over and around the areas to be coated of the component.
- the opening of the attachment base plate can be surrounded by at least one seal. This also ensures that the hard material particles are actually provided only in the areas of the component that are to be coated.
- the cover has at least one fixing device for releasably securing the cover to the component. This also makes it possible to securely position the cover on the desired component surfaces. Furthermore, it is possible that between the attachment base plate and the mold opening a form-fitting surrounding the opening seal is formed. 5 This ensures that the hard material particles are embedded only in the areas of the component that are actually to be coated with the aid of the galvanically applied metallic matrix layer.
- the hard material particles may consist of (cubic) Bohrnitrid, ceramic, titanium carbide, tungsten carbide, chromium carbide, alumina or zirconia or a mixture thereof.
- the particle size is usually between 30 o to 200 microns, but other particle sizes can also be used.
- the cover can be rigid or flexible.
- the inventive method ensures a simplified and cost-effective process flow.
- a sufficiently high concentration of hard material particles is provided for the coating without these being distributed freely and uncontrollably in the electrochemical coating solution.
- attaching the receiving device above and around the area of the component to be coated is technically easy to carry out.
- unneeded hard material particles remain in the receiving device.
- This can then readily be used for a next coating step, provided that the concentration of hard material particles is still sufficient.
- the receiving device consists of a material which is permeable to the electrochemical coating solution, the galvanic process, ie the formation of a metallic matrix layer, in particular a nickel-containing layer on the region of the component to be coated, does not hinder the embedding of the hard material particles.
- the galvanic forming of the filling layer between the embedded hard material articles according to method step c) can be carried out, for example, after removal of the receiving device.
- step 5 c) a rotation of the component, wherein the axis of rotation of the component is horizontal.
- the rotational movement of the component ensures a uniform distribution of the hard material particles on the component surface to be coated. Due to gravity, the hard material particles are pressed in an upper position of the rotating component against the component surface to be coated.
- the component is completely introduced into the immersion bath with the electrochemical coating solution. But it is also possible that the component is only partially or partially immersed in the galvanic immersion bath.
- integrally bladed rotor disks or rotor rings BLISK or BLING
- the rotation of the BLISK or BLING with horizontally oriented rotation axis results in the desired uniform distribution of the hard material particles on the blade tips.
- the receiving device with the opening is placed positively over the region of the component to be coated, wherein the opening is surrounded by a flexible gasket.
- the flexible seal can be laminated in the edge of the opening.
- the receiving device is connected in the region of its opening with a top base plate, such that the opening of the receiving device corresponds to an opening in the top base plate and the top base plate is releasably attachable to a cover.
- the cover has at least one mold opening for receiving the regions of the component to be coated, wherein, in method step a), the opening of the Base plate is positioned with the opening of the receiving device over these areas.
- This process step also ensures that only predetermined regions of the component are coated with the protective layer having the hard material particles.
- the components or component areas to be coated can be positioned in a form-fitting manner quickly and easily by means of 5 of the mentioned mold openings in the cover.
- the cover is releasably secured to the component prior to method step a).
- the cover can be designed such that it can accommodate one or more component areas to be coated in corresponding mold openings.
- the cover can be flexible or rigid.
- the electrochemical coating solution used in process step b) and / or process step c) contains nickel.
- it may be a nickel sulphate solution.
- a massive nickel anode is used for the projecting into the galvanic immersion anode.
- Other metallic coating materials are also conceivable and are in particular based on the metallic composition of the component to be coated.
- the hard material particles used usually consist of (cubic) boron nitride, ceramic, titanium carbide, tungsten carbide,
- the filling layer formed in method step c) fills the intermediate space between the hard material particles, wherein the hard material particles are geometrically embedded in the filling layer in a range between 65 and 90%. This advantageously results in a secure fixation of the hard material particles in the metallic matrix, wherein it is additionally ensured that a sufficiently large area of the hard material particles still protrudes from the matrix surrounding it.
- pretreatment of titanium components may include the following steps:
- An inventive component is manufactured according to a method described above, wherein the component is in particular a blade tip of a blade of a compressor of an aircraft engine, in particular a BLISK or BLING.
- These bladed disks or rings consist in particular of titanium or nickel alloys. But it is also possible that these components are made of metal matrix composite-5 titanium-based materials. Furthermore, there is the possibility that these components consist of so-called intermetallic materials of the TiAl or Ti 3 Al type.
