摘要:
The turbine parts, when they are used, form oxide layers which by the undesirable rapid growth thereof generate the damage of the parts substrate. The inventive method consists in depleting the part in an element in such a way that the oxide layer is reduced.

摘要:
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:
The invention relates to a method for the protection of openings in a component, produced from an electrically-conducting material, in particular, from metal or a metal alloy, during a machining process against the ingress of material, whereby the openings are sealed with a filler material before the machining process, which is removed again after the machining process. The machining processes particularly concern coating processes and welding processes. Said method is characterized in that an electrically-conducting filler material is applied, the electrical conductivity of which matches the electrical conductivity of the base material.
摘要:
Electrolytic methods are used to treat large external surfaces. There is described a method for internally coating through-holes of a wall, wherein an electrolyte flows through the through-hole during the treatment and deposits material on the respective inner surface. A single electrode is being used for at least two through-holes.

The cold spraying process according to the invention uses cold gas streams whose properties (temperature (T), particle density (p), pressure (p), particle velocity (v)) are variably changed such that they can be adapted to the desired properties of the coatings.

The invention provides a method for determining the position of a channel which has been electrochemically machined in a workpiece by an electrolyte and/or the wall thickness which is present between the electrochemically machined channel and the surface of the component, in which magnetic particles are added to the electrolyte used during the machining, the magnetic fields associated with the magnetic particles are detected, and the position of the electrochemically machined channel and/or the wall thickness which is present between the electrochemically machined channel and the surface of the component is determined on the basis of the detected magnetic fields.
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.
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.
