Friction and wear are tribological problems, for the solution of which the NanoZ uses its interfacial and microstructural analytical methods. Different methods are used, such as mechanical preparation, light microscopy, scanning electron microscopy with EDX and EBSD, a focused ion beam with EDX or transmission electron microscopy with EDX and EELS.

Our analytical methods allow us to analyze the near-surface boundary and reaction layers in detail. High-resolution imaging and spectroscopic investigations (EDX, EELS) also capture the chemical composition and atomic structure of the reaction layer. Transmission electron microscopy (TEM) can be used to identify phase transitions, layer thicknesses and changes on an atomic scale. We support you in load characterization to elucidate the causes of material fatigue and wear. The knowledge gained in this process helps to improve the running properties and service life of machine elements.
