Abstract: The tribological study of the parameters of piezoactuator when switching over contacts a trib ocouple deals with of rotation of piezoactuator steady during 500 m when the rotor from polished steel C45 (HRC 50, Ra = 2 μm) is used. Often the rotation speed leaps up to 16–18 min–1. The coating with fluoroli gomeric material stabilizes the rotation and continuous operation of piezoactuator. The steady rotation speed starts from a 50 m run (350 rotor revolutions, i.e., cycles of repeating impacts on the surface). The lower dam age of the friction surface takes place after a 500 m run when the rotor is coated with fluoroligomeric mate rial. Scratch tests show that steel surface with the fluoroligomeric layer has a lower hardness and 20% higher elasticity compared to a noncoated surface
