Your challenge

You are responsible to find the solution of a specific problem concerning corrosion processes and/or (de-)adhesion of metal covering films? You are looking for a partner to investigate your specimen and analyze surface and interface pro-perties to get the answers to your questions?

We would be glad to support you.

Our competence and mission

At the Laboratory for Materials and Corrosion Analysis (MCA) complex materials as used in technical applications and their corresponding degradation processes are studied.

We offer our partners:

» Analysis of metal sur faces » Corrosion analysis of metals, polymers,

ceramics and composites » Analysis of interfacial degradation processes

and corrosion products » Layer (de-)adhesion studies

as well as

» Consulting » Professional reporting

Analysis methods

We offer a wide variety of analysis methods to get an insight into corrosion processes and adhesion or de-adhesion. Normally failure detection will be finalized by the evaluation of results of several techniques.

Surface and interface properties

» FE- SEM pictures to image the surface » FTIR- and Raman Microscopy, X-Ray Photo

electron Spectroscopy (XPS) and Scanning Auger Microscopy (SAM) of thin films, metals, polymers and ceramics to determine surface compositions

» Scanning Kelvin Probe Force Microsopy (SKPFM) to analyze surface potential and topography simultaneously

» Imaging Ellipsometry to measure film thick- ness and optical properties of films

» Formability of barrier films and Peel Force measurements to determine adhesion forces unter ambient and corrosive conditions

» Contact Angle measurements (sessile drop, polymer melts, dynamic contact angles) to analyze surface energies

In-situ analysis of corrosion products via Raman spectroscopy
