Schematic illustration of material flows and reactions occurring in a tribocorrosion system, with the first body: a passive metal; second body: an inert counter-body and third body: generated from the resulting process. In a tribocorssoion process, the wearing process causes the detachment of the wear particles from the metal (1), which would either be ejected (2) or transferred to a third body (3); Subsequently, the third body can adhere to the counter body (4); or fragment into smaller particles (5); or the metal (6); Upon reaching a critical size, the third body can be ejected from the contact (7); In addition, wear accelerated corrosion can be observed in two locations: third body (8) and exposed metal (9) (occurring immediately after the wear particle detaches) (adapted from reference [21], with permission from © Elsevier).
