Coatings

At the RMS Foundation we can offer you the following services in the area of coating testing:

Services for coatings (general):

Thickness of coatiings:
  • Non-destructive coating thickness measurement by means of eddy current method (DIN EN ISO 2316) and magnetic inductive method (DIN EN ISO 2178). Thus, the thickness of non-magnetic coatings on steel and iron (Fe) as well as of non-conductive coatings on all metals can be measured. The measuring method allows a layer thickness determination in a measuring range of 0 - 2000 µm (Fe) or 0 - 1200 µm (metals). With a measuring stand, precise and pinpoint measurement is possible even on small samples.

  • Preparation of a transverse section. The thickness of one or more layers can be determined using a microscope (EN ISO 1463) and / or scanning electron microscope (SEM).

    Contact person: Moritz Liesegang
Surface of coatings:
Composition of coatings:

Thickness of coatings (several µm):

Thin coatings (sub-µm):

  • XPS, with depth profile if necessary

Multilayer systems:

  • SEM-EDX at cross sections
  • XPS at oblique sections

 

 

Wettability of a solid surface

Description: With complete wetting (spreading), the contact angle is 0°. Between 0° and 90° the solid is considered wettable, above 90° non-wettable. In ultrahydrophobic materials with the so-called lotus effect, the contact angle approaches the theoretical limit of 180°.
Standard(s): ASTM D7334 / DIN 55660-2

Standard(s): EN ISO 1463
