Fundamentals of Metallic Corrosion in Fresh Water

Corrosion in fresh water very often results in pitting so that, because of statistical variation in pit geometry, experiments under identical conditions will not yield identical results. The result of changes in experimental conditions may appear to be contradictory.

Corrosion tables — Materials …

The corrosion data in this section is mainly based on the results of general corrosion laboratory tests, which are not strictly comparable with actual service conditions. The corrosion tables provide an initial guide to the selection of materials and are intended to facilitate understanding of the different types of corrosion damage that can arise due to poor material selection.

Corrosion in the Oil Industry - Schluerger

Most metals exist in nature as stable ores of oxides, carbonates or sulfides. Refining them, to make them useful, requires energy. Corrosion is simply nature’s way of reversing an unnatural process back to a lower energy state. Preventing corrosion is vital in every step in the production of oil and gas. Corrosion in the Oil Industry Denis

Corrosion testing of metals in contact with calcium

Chloride stress corrosion cracking in austenitic stainless

Chloride stress corrosion cracking (CLSCC) is one the most common reasons why austenitic stainless steel pipework and vessels deteriorate in the chemical processing and petrochemical industries. Deterioration by CLSCC can lead to failures that have the potential to release stored energy and/or hazardous substances.

17.6 Corrosion – Chemistry

Corrosion is usually defined as the degradation of metals due to an electrochemical process. The formation of rust on iron, tarnish on silver, and the blue-green patina that develops on copper are all examples of corrosion. The total cost of corrosion in the United States is significant, with estimates in excess of half a trillion dollars a year.
