Crevice corrosion develops quite similar to pitting corrosion after the initiation stage. Examples of such geometries include flanges, gaskets, disbonded linings/coatings, fasteners, lap joints and surface deposits. Erosion Corrosion arises from a combination of chemical attack and the physical abrasion as a consequence of the fluid motion.

Effect of Cracking on Corrosion of Steel in Concrete

It is generally recognized that cracks provide easy access to ingress of chlorides in concrete and hence, the initiation of corrosion of steel in cracked concrete occurs at early stage. However, wide variety of results on the effect of crack widths on corrosion of steel in concrete are reported in many studies. Apart from crack width, the crack depths, cracking frequency and healing of cracks ...
