Abstract
The work reports for the first time galvanic current measurements for the friction material – backplate couple. In particular, two configurations including different friction materials and a steel-based backplate are considered. Measurements are performed using Linear Sweep Voltammetry (LSV) and Zero Resistance Ammeter (ZRA) –based techniques and allow to: 1) investigate the interplay between galvanic currents and localized corrosion events at the interface between each investigated friction material and the corresponding backplate; 2) correlate the corrosion potential of stand-alone materials with that of multilayered specimens; and 3) identify friction materials which show a sacrificial anode behavior with respect to the backplate.
