摘要:
Protective layers, according to the prior art, achieve their protective function b depletion of a defined element that forms a protective oxide layer or that is exhausted as a sacrificial material. Once said material is exhausted, the protective function cannot be maintained. The invention is characterized by using particles (1) that contain a sustained-release depot of the exhaustible material. For this purpose, the material is present in a superstoichiometric form.

Cracks are conventionally difficult to clean which often leads to damage to other regions of the component for cleaning. According to the invention, a plasma cleaning method is used, whereby a pressure and/or a separation of an electrode to the component are varied, in order to achieve a plasma cleaning in the crack.

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:
A process is intended to allow simple and particularly reliable electrolyte generation and conditioning from metal-containing used electrolytes and/or used process solutions and/or pulverulent metal wastes. For this purpose, waste products containing metal ions from metal surface treatment processes are to be treated by producing and/or using a metal ion mixed solution, replacing anions contained in the metal ion mixed solution with anions selected for an intended use selected and selectively removing metal ions which are categorized as unsuitable for the intended use selected from the metal ion mixed solution prepared in this way.
