A prototype for surface degradation measurement on micrometric and submicrometric scale for the tribological studies of the surfaces.
The tribometer allows to calculate the instantaneous Archard's wear coefficient for bulk and coated samples. It quantitatively asses the value of friction coefficient for the coupling between the part and the counterpart, in the range of motion conditions and heavy loads.
Compared to the tribometers currently present on the market this approach is very innovative in many aspects.
It is possible to choose arbitrarily the resulting direction of the imposed stress by modulating the resulting shear stress continuously, and the contact pressure applied (also variable arbitrarily through the use of appropriate loads) .
Stress can be set in different condition: innovation in the choice of the mode of contact and the direction of rotation imposed.
It is possible perform:
- pivotal motions (rotation axis lying in the plane of rotation of the counterpart);
- sliding contacts (rotation axis of the part outside the plane of rotation of the counterpart with concordant directions of rotation)
- severe wear motions (axis of rotation of the part external to the plane of rotation of the counterpart with disconcordant directions of rotation).

Ability to evaluate instantly  the values ​​of wear and friction coefficients.

Ability to qualitatively assess the adhesion properties of the coating.

Possibility to realize different  wear mechanisms.
Load control with the precision of 1 g, full control of grinding and sample  speeds, possibility to handle 3-axis movement with the resolution of 1 micron.
