  • Patent number: 12025551
    Abstract: Methods and equipment for determining conditions of adhesion between a first and a second mechanical element are disclosed. The mechanical elements are attached respectively to a first and second support, which are immersed in an electrolyte together with a counter-electrode and a reference electrode to form an electrochemical cell. The second mechanical element is a working electrode being connected to an insulated electric wire that is also connected to the counter-electrode. A first uncovered face of the second element is pressed against the first element. A potential is applied to the second element of at least one predetermined value and/or a predetermined electrical current. The method can include 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.
