Services

The topics of our high quality services are closely related to our research activities. For applied research for industries, SMEs, associations, federal agencies and private customers we maintain a modern and efficient testing infrastructure and analytic equipments. We characterise in particular mechanical properties of materials, provide state of the art surface and microstructure analysis facilities and offer prototyping facilities for surface patterning via UV-, electron- and ion beam patterning methods.

Our solution to your problem
Electron Microscopy
High resolution image of a single wall nanotube

Our electron microscopy lab offers high-quality imaging. Different microscopes for different purpose are available. A Hitachi S-3600 with variable pressure is used for common work and electron beam lithography. For high resolution imaging our Hitachi S-4800 is the best choice. This electron microscope is equipped with analysis tools like EDX, EBSD and STEM. The Zeiss DSM 962 has the function of a micromechanical testing lab. Specialized equipment allows us to perform micromechanical testing (indentation, tensile, compression) inside the scanning electron microscope. A special 3D backscatter detector allows us to get three dimensional images. Calculations like depth profil, volumes and more can be performed.

Mechanical testing on microscopic and macroscopic scales
Micro-Compression tests of liquid-filled micro-capsules allow to study the relase process of a liquid at the capsule failure

We offer mechanical testing on the macroscopic scale (tensile and bending tests, hardness measurements, adhesion tests) as well as on the microscopic scale (nanoindentation, nanoscratching, microcompression). A speciality of our lab is micromechanical testing inside the scanning electron microscope (indentation, tensile, compression) that allow a real-time observation of the sample during deformation.

Chemical and microstructure analysis
analytical Chemist in wild west.....

Advanced Glow-discharge optical emission spectrometry (GD-OES, Instrument Type JY5000RF) allows fast quantitative bulk analysis of almost all alloy types and depth-profiling with nm resolution up to several µm depths of conductive and non conductive coatings. An additional advantage of GD-OES is the possibility to measure hydrogen qualitatively. Micro structural analysis includes X-ray diffraction (Siemens D5000), Raman and Micro-Raman (Dilor XY modular Micro Raman) analysis. Thermal analysis can be performed with our TG/DTA instrument Netzsch STA409cell in the range of room temperature up to 1600°C.
