CORROSION is the electrochemical reaction of a material and its environment. This article addresses those forms of corrosion that contribute directly to the failure of metal parts or that render them susceptible to failure by some other mechanism. In particular, mechanisms of corrosive attack for specific forms of corrosion are described.

A SIGNIFICANT DISCOVERY in the corrosion of generators occurred in the 1990s-crevice-corrosion cracking in water-cooled generators. Before delving into crevice-corrosion cracking, however, this article reviews the generator industry experience with stress-corrosion cracking (SCC) of 18Mn-5Cr alloy retaining rings.

Billions of dollars are spent annually for the replacement of corroded structures, machinery, and components. Premature failure of bridges or structures due to corrosion can also result in human injury, loss of life, and collateral damage.

IN MANY APPLICATIONS of structural materials-aerospace, automobiles, power generation-increasing demands are being made for materials with temperature capabilities greater than those of superalloys. Intermetallics with higher melting points can replace superalloys with inadequate melting points (Ref, Ref, Ref).

A concept of uniform corrosion should be defined as a basis to which localized corrosion can be compared. Idealized uniform corrosion occurs when the flux of metal ions from the surface and the flux of cathodic reactants to the surface are uniform to atomic dimensions.
