Abstract: Tribological investigation of the parameters of piezo-actuator when changing the contact conditions of tribo-pair is presented. Investigations show that the rotation of piezo-actuator is not steady during run when the rotor of polished steel C45 is used. Often droppings of rotation speed up to 16—18 min-1 are taking place. Processing with fluoroligomeric material stabilizes the rotation and continuous operation of piezo-actuator. The steady rotation speed starts from 50 m ran (350 rotor's revolutions). Lower damage of friction surface is taking place after 500 m run when rotor is coated by fluoroligomeric material. Scratch tests show that steel surface with fluoroligomeric layer has lower hardness and 20% higher elasticity comparing to non-coated surface
