When conducting a visual inspection in conjunction with an ECDA dig, operators should look for the telltale tubercle--a hard deposit of soil and metallic corrosion
product at the coating defect.
Microorganisms are ubiquitous in oil and gas environment and may influence both the initiation and propagation of all known types of metallic corrosion
Adsorption plays an important role in the inhibition of metallic corrosion
by organic inhibitors.
and ion migration are both electrochemical phenomena that occur in the presence of moisture and ionic contamination found in dust.
The influence of different artificial saliva on metallic corrosion
was investigated by measurements of open circuit potential, polarisation curves, chosen owing to its high rate of corrosion.

The study, Corrosion Cost and Preventative Strategies in the United States, which was funded by the Federal Highway Administration, is a comprehensive look at the cost of metallic corrosion
on the U.
This article will consider only metallic corrosion
and oxidation, although many of the surface-analytical techniques discussed can be applied to study the degradation of non-metals.
gov) estimated the annual cost of metallic corrosion
in the United States is between $300-350 billion.
Hence, surface treatment of a metal alloy prior to the development of coating is essential in the prevention of metallic corrosion
and to withstand during long-term implant condition.
Federal Highway Administration (FHWA) in 2002, metallic corrosion
cost the United States approximately $276 billion, or 3.
