Corrosion process is a complicated physio-chemical phenomenon involving effects at the atomic level of events. Present article provides a view of corrosion as a largely quantum phenomenon with links to several branches of novel physics. We discuss quantum effects which can affect the corrosion scenario, such as energy transfer and energy cumulation processes. Coulomb blockade, spontaneous collapse of quantum super-positions, etc. A complimentary viewpoint is to look at the corrosion as a self-organization process which has some non-trivial connections to quantum physics of information and spontaneous pattern formation in non-linear systems. These latter aspects are especially relevant for corrosion passivation.
