Narrow openings, gaps, spaces, pores etc. between metal-metal components or metal-non-metal components may provoke localized corrosion.. NOTE: unintentional crevices (seams, cracks etc.) can also act in the same way. oxidization. of a metal, and the oxide flaking off.. Oxidized metal is commonly called rust.
