Process for the Production of Components with a Precisely Defined Porosity


Kurzfassung

The technology relates to a process for a much cheaper and easier production of components with a precisely defined porosity. By applying the method of cold gas spraying, superior components can be produced, which are commonly used in separation processes or functional testing and calibration of leak detectors.


Hintergrund

Porous components or components with a defined porosity are used, among other things, in separation processes and for functional testing and calibration of leak detectors for leak testing. In separation processes, a defined pore size is important for excluding the size of the mixture of substances to be separated. In connection with leak detectors, a defined gas permeability, often expressed as the leakage rate, is the decisive property.


Problemstellung

Simple production of small leaks, which can be created as a component as well as introduced onto existing components. These can, for example, serve as reference leaks for leak detectors or for ultra-fine filtering, etc.


Lösung

Production of nano / microporous layers using cold gas spraying.


Vorteile

  • Very easy to apply
  • Precisely defined porosity
  • Cheaper than established processes

Anwendungsbereiche

Calibration leaks, filtering, all kinds of separation processes, especially useful in the context of very volatile substances like hydrogen.
