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:
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.

In the process according to the invention for protecting openings in a component made from an electrically conductive base material, in particular from metal or from a metal alloy, during a treatment process, preventing penetration of material, prior to the treatment process the openings are closed up using a filling material which is removed again following the treatment process. The process according to the invention is distinguished by the fact that chains of Si—O—Si and/or Si—O—C are used as filling material.
摘要:
Short fibers in a solder or a welding material often do not have the desired strength. The invention uses fiber mats which have been introduced onto a surface or into a recess of a metallic component.
摘要:
Inner coatings according to the prior art often do not produce a uniform coating. The method according to the invention for the coating of a component with a cavity is characterized in that a coating material is mixed with a carrier material and introduced into the cavity, the carrier material decomposing at the evaporating temperature of the coating material, or has already decomposed, and the coating material being deposited from the gas phase on the component.
摘要:
A method for producing a cast metal piece and a cast metal piece are provided. An information element includes at least one piece of information. The information element is produced from a magnetizable material and the information is deposited n the magnetizable material and is cast into the information element during casting of the price, the casting temperature being above the Curie temperature of the magnetizable material of the information element.
摘要:
In a method for producing a component (20) with a coating (24) containing nanoparticles (21), it is provided that, in order to introduce the nanoparticles (21) into the coating (24), a film (19) with the dispersely distributed nanoparticles (21) is applied to the surface (22) to be coated, which decomposes with incorporation of the nanoparticles (21) during the actual coating operation and is thereby not incorporated into the layer.
摘要:
In a method for producing a particle (10) containing functional layer (310, 400, 600), nanoparticles are introduced into the functional layer material (320, 410, 610), the nanoparticles having a particle core (20) and a particle shell (30) surrounding the particle core. The material (K) of the particle core has a higher chemical activity than that of the particle shell and the material (M) of the particle shell allows diffusion of the material of the particle core through the particle shell into the functional layer material.
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:
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.
