Laboratory studies on the mechanism of perforation (crevice) corrosion on bare steels are described. A rapid pitting-type attack was initiated only after specimens were allowed to cycle wet and dry with the resultant formation of an adherent magnetite film. The most rapid attack usually did not occur within the crevice itself, but rather pitting was most severe on the surrounding metal. The crevice geometry did not promote significant galvanic cell effects between exposed and unexposed steel surfaces for the systems studied.
