Nano-mechanical and tribological characterization of thin films


Abstract:
The present work gives an overview of the different methods and technologies that can be used for evaluation of tribological and nano mechanical properties of coatings and thin films. Reciprocating wear, scratch-adhesion, nano-indentation and instrumented micro tests are reviewed here. The Universal Nano & Micro Tester with multiple sensors (indentation and wear depth, normal and lateral forces, contact electrical resistance, acoustic emission, temperature) and integrated both atomic force and optical microscopes has been utilized to characterize mechanical properties of thin films, with in-situ monitoring their changes during the tests. This study shows how multiple simultaneous parameters measurements can give a better knowledge of the surface properties.
