However, the nature of oxidation, metal dissolution, and interface reactions between the oxide film and the metal surface and all the element-specific effects remain elusive. The reason is that the underlying mechanisms are hidden in the nanoscale, and the atomic configurations and partitioning ...
Corrosion is the destructive attack of a metal by chemical orelectrochemical reactionwith the environment (Uhlig). Despite different definitions, it can be observed that corrosion is basically the result of interaction between materials and their environment. Up to the 1960s, the term corrosion was ...
1) out of which chloride induced corrosion is a particular case where chloride ions, come from the environment, reach the rebar and reduce the pH breaking the passive shield of the rebar and allowing corrosion processes. Sign in to download full-size image Fig. 1. Corrosion cell. It is ...
Introduction The basic importance of chromium in relation to passivity in the resistance of steels to aqueous corrosion is paralleled by its role as the most important alloying element in practice in securing the high-temperature oxidation resistance of heat-resisting steels. It is not surprising, ...
A variety of organic compounds have been reported to be effective as corrosion inhibitors during acidization in industrial cleaning processes4,5. Organic additives prevent the adsorption of chloride ions and/or the formation of a more resistant oxide film on the metal surface6. The inhibition ...
Corrosion of metals is the spontaneous chemical (oxidative) destruction of metals under the effect of their environment. Most often it follows an electrochemical mechanism, where anodic dissolution (oxidation) of the metal and cathodic reduction of an oxidizing agent occur as coupled reactions. ...
This process involves two electrode reactions that can occur in a spontaneously way at the interface between the metal and the aqueous environment according to the thermodynamic’s Law; One, is the reaction of metal-base with chemical species from the environment (i.e. anodic-oxidation reaction,...

A typical weakness of epoxy resins is the relatively poor barrier effect, especially for water and moisture. A low permeability gives the chance to apply epoxy products in fields such ascorrosion preventioncoating, electronic and optoelectronic packaging, fuel storage, food packaging, and also as coa...
The conditions for initiation and the subsequent development of the severity of corrosion of metal alloys in the short term continue to be of research interest. However, for most physical infrastructure the critical issue often is the development and progression of corrosion under some level of oxyge...
