Severe concentration cell corrosion involves segregation of aggressive anions beneath deposits. Concentrations of sulfate and chloride, in particular, are deleterious. Acid conditions may be established beneath deposits as aggressive anions segregate to these shielded regions. Mineral acids, such as hydrochloric and sulfuric, form by hydrolysis. The mechanism of acid formation is discussed in Chap. 2. 

Here we present only one effect in detail which also is expected to occur in metallic alloys the enrichment of vacancies in the interfacial region (Fig. 4). For the chosen parameters, the density reduction 5p in the center of the interface even is a few percent in the fully segregated limit. However, 5p 0 as T Tc.
