A number of tests were carried out on the Universal Nano+Micro Tester mod. UNMT-1. The
general appearance of the tester is shown in Figure 1. It is a highly precision instrument for
nano and micro mechanical and tribological testing of practically all types of thin films and
coatings, including metals, ceramics, composites, polymers, etc. It provides a combination of
rotary and linear, including reciprocating, motions in both vertical and horizontal directions,
and measures numerous parameters such as normal and lateral forces and torques, wear and
deformation, contact acoustic emission, contact electrical resistance, temperature, etc. An
optional nano-indentation head measures nano-hardness and elastic modulus of thin films.
The unique modular design provides the capability of fast switching between multiple testing
modes (such as friction, wear, micro-scratch, nano-indentation, AFM imaging, etc.) by simply
swapping the easily-replaceable drive stages and sensors. A high-frequency multi-channel
data-acquisition system, with data samp领 at thousands times per second, allows for
detection of almost instantaneous tiny sub-micro-contact and sub-micro-failure events in
sophisticated test sequences. Integrated optical microscopy allows for precision sample micropositioning,
digital video of the in-situ dynamics of surface failure, and micro-images of wear
tracks, indents and scratches. Optional integrated atomic force microscope provides nanoimaging
of test surfaces, wear tracks, indents and scratches, both periodically during testing
and post-test.
