More details: Although thermodynamically non-noble, many metals and their alloys are in practice resistant to corrosion with equilibrium potentials much higher than their reversible potentials (see the practical potential series, figure 11.17 of Surface, Interfaces, and their Applications I). This behavior is due to a spontaneous formation of a thin protecting oxide layer, the passive layer, as a product of the anodic metal dissolution.CMOS (passivation)
