When a metal or metal alloy is immersed in an electrolyte made of a conducting material of sufficient oxidizing power, such as moist soil, it will corrode according to a well-defined electrochemical mechanism. dc corrosion is a result of dissolution of material due to oxidizing reactions, liberating electrons and forming positive ions transported into the electrolyte, leading to material loss. The current-potential relationship governing this electrochemical process termed polarization, is non-linear. This relationship is often represented by a polarization curve, which is typically, an experimentally determined function. There are a number of parameters that can contribute to the final characteristics of the polarization curve within a system ranging from material parameters (e.g. material, geometry) to environmental factors (e.g. composition of the electrolyte).

Information and test methods available to evaluate the effectiveness of cathodic protection (CP) systems used to protect the steel reinforcement of conventionally reinforced atmospherically exposed concrete structures.
HISTORICAL DOCUMENT. Guidelines for sacrificial (galvanic) cathodic protection (SACP) of reinforcing steel in atmospherically exposed concrete elements or structures. Not applicable to nonferrous, coated or galvanized reinforcement.
This AMPP standard practice presents guidelines for galvanic cathodic protection (GCP) of reinforcing steel in atmospherically exposed concrete elements or structures. These guidelines are intended for owners, engineers, architects, contractors, and those concerned with the mitigation of reinforced concrete corrosion through the application of GCP systems. The information in this standard as it relates to GCP systems is intended for atmospherically exposed concrete structures and is not applicable to concrete with nonferrous reinforcement or epoxy-coated, galvanized, or other types of coated reinforcement. GCP applications for buried and submerged reinforced concrete structures are not addressed in this standard.
Corrosion of reinforcing steel is recognized as the major cause of the deterioration of reinforced concrete structures. Exposure to de-icing salts, seawater and chloride-containing set accelerators, plays a significant role in reinforcing steel corrosion (Figure 1). When the chloride content at the rebar level exceeds the threshold for initiation of corrosion, the passivation protective film on the rebar surface is destroyed and a corrosion cell can form either on the same piece of rebar with anodic and cathodic sites adjacent to each other, or a macro-cell between two different layers of reinforcement.
To restrain the failure of plate heat exchanger in customer boiler working fluid, the effect of crevice former type on the corrosion behavior of Type 316L (UNS S31603) stainless steel plate was investigated using electrochemical methods and surface analysis in chloride-containing synthetic tap water.
