METHOD AND EQUIPMENT FOR STUDYING AND ESTABLISHING THE PHISICO-CHEMICAL CONDITIONS OF STICTION BETWEEN A BRAKING ELEMENT AND AN ELEMENT TO BE BRAKED

摘要

Method wherein a first and a second mechanical element (4, 5) are attached respectively to a first and second support (7, 9), which are immersed in an electrolyte (21) together with a counter-electrode (19) and a reference electrode (20) in order to form an electrochemical cell (2) wherein the second mechanical element thereof is a working electrode being connected to an insulated electric wire (12) connected as well the counter-electrode to a potential/current generator (23); a first uncovered face (15) of the second element, for the remainder thereof incorporated within the second support, is pressed against the first element (4) and a potential being applied to the second element of at least one predetermined value and/or a predetermined electrical current is passed, detecting the electrical current that is transmitted through the electrolyte as a function of the potential applied and/or the potential that is established as a function of the predetermined current.
