Passive metals
WebThe potential increase no longer affects the current because of the passivation film on the metal surface and current is a constant in this region and known as the passive region. The current does not change with increasing potential at this region. At the beginning of the transpassive region, the high potential starts to destroy the passive film. WebPassivation is the loss of chemical reactivity experienced by certain metals and metal alloys under particular environmental conditions. The metals or alloys become inert and act as …
