... were performed on tribometer Bruker UMT TriboLab ( fig. 2a) with a pin-on-disc configuration ( fig. 2b) as a disc. The disc had to be gently grinded and polished up to less than Ra 0.025 m to avoiding the seizure at high speed (see fig.1a). The measurement was carried out for temperatures of 40 °C. The normal force was altered from 1 to 20 N in dependence on sliding speed. The revolution of ...

... each step (one step = one speed), the 16 change in direction of rotation was programmed for better flooded of contact (see fig. 4). Sometimes, the data included four types of instabilities: (i) high level of noise probably caused by resonance of metal strip keeping the holder of pin (see fig. 2b); (ii) unsymmetrical friction force for one and other direction probably caused by seizure or bad flooding of contact; (iii) increase in friction force during one step caused by seizure, (iv) peak in friction force caused by static friction when the direction is changing. The delivered SW with tribometer cannot recognize these ...
