Two high performance Nanoindenters are available for testing at loads up to 10 Newton at nm displacement and nN force resolution. The instrumentation provides access to:

- hardness and modulus
   as a function of indentation depth
- scratch and wear testing
- adhesion of films on substrates
- micro bending and compression
- dynamic testing of polymers
- temperature dependent tests
- fracture toughness

The patented continuous stiffness technique (CSM) yields the respective values for each point of the measurement throughout the whole loading cycle and enables the user to conduct dynamic experiments to characterize the time dependent mechanical behavior of the sample.

Scratch tests provide information about the wear resistance of surfaces as well as the interfacial adhesion between coatings on a substrate. Interactive scanning allows characterizing the indent and scratching geometries in the nanometer scale and to position indents within several nanometers.

Our laboratory is equipped with a set of SPM devices to determine the topography down to subnanometer resolution. By using functionalized tips, electronic, magnetic and thermal properties are obtained as a function of the surface coordinates. Measurements are performed with latest technology and with high accuracy, minimizing mechanical effects on the tested specimens.
