摘要:
The invention relates to a method for electrochemically coating or stripping the coating from components (1). In said method, the component (1) acts as an electrode and an electric field is established between the component (1) and a counter-electrode (3), said field allowing the deposition of a coating material that is dissolved in an electrolyte or the removal of a coating material (11) on the surface (2) of the component. During the deposition or removal process, the component (1) is covered with structures (5) consisting of an electrically insulating material.

The invention relates to a method for producing a component (20) with a coating (24) containing nanoparticles (21). According to the invention, 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.

A component (1) for arrangement in the duct of a turbine engine is provided with a coating (5), which has a surface structure with scales (9) which overlap each other in the direction of flow (S).
摘要:
In prior art, through holes often have to be after-treated manually. Disclosed is a method allowing through holes (10) to be after-treated in a chemical or electrochemical manner with the aid of a material-removing agent (13, 16, 33), the outer surface (45) located around a discharge port (51) of the through hole (10) being protected accordingly from being attacked by the agent (13, 16, 33) that is to be removed.
摘要:
The invention relates inter alia to a method for producing a cast piece (100), especially a cast metal piece, comprising at least one information element (5) carrying at least one piece of information. The invention is characterized in that the information element (5) is produced from a magnetizable material (10) and the information is deposited in the magnetizable material and is cast into the information element during casting of the piece, the casting temperature being above the Curie temperature of the magnetizable material of the information element.
摘要:
The invention relates inter alia to a method for removing a protective coating (40) from a component (10), especially a turbine blade. According to the invention, the protective coating (40) is removed, using mechanical shock waves (S1, S2) having a shock wave repetition rate (fs) below 20 kHz.
摘要:
The invention relates to 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 colour reaction which causes the colour of the coating to change irreversibly.
摘要:
The invention relates to a cold gas spraying method with the aid of which a substrate to be coated can be coated with particles. According to the invention, it is provided that microencapsulated agglomerates of nanoparticles (27a, 27b) are used as particles. This advantageously allows the advantages that accompany the use of nanoparticles to be used for the coating. The nanoparticles 27a, 27b are held together by microencapsulations 26c, wherein the microencapsulated particles 19 formed in this way that are used in the cold gas spraying method have dimensions in the micrometre range, thereby allowing them to be used in the first place in cold gas spraying. The microencapsulated nanoparticles may be used for example to produce a UV protective coating on lamp bases for gas discharge lamps.
