Corrosion - Wikipedia
WebCorrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion. [1] [2]
Corrosion - Simple English Wikipedia, the free encyclopedia
WebCorrosion is the breakdown of materials due to chemical reactions. It is usually oxidation with air molecules and often in the presence of water. Corrosion also occurs when an acidic/basic corrosive substance touches another material. When a material corrodes, its physical properties change.
Corrosion engineering - Wikipedia
WebCorrosion engineering is an engineering specialty that applies scientific, technical, engineering skills, and knowledge of natural laws and physical resources to design and implement materials, structures, devices, systems, and procedures to manage corrosion. [1] From a holistic perspective, corrosion is the phenomenon of metals returning to ...
Rust - Wikipedia
WebRusting is the common term for corrosion of elemental iron and its alloys such as steel. Many other metals undergo similar corrosion, but the resulting oxides are not commonly called "rust". Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances.
Galvanic corrosion - Wikipedia
WebGalvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence of an electrolyte.
Pitting corrosion - Wikipedia
WebPitting corrosion, or pitting, is a form of extremely localized corrosion that leads to the random creation of small holes in metal. The driving power for pitting corrosion is the depassivation of a small area, which becomes anodic (oxidation reaction) while an unknown but potentially vast area becomes cathodic (reduction reaction), leading to ...
What Is Metal Corrosion and Why Does It Occur? - ThoughtCo
WebUpdated on May 16, 2019. Corrosion is the deterioration of a metal as a result of chemical reactions between it and the surrounding environment. Both the type of metal and the environmental conditions, particularly gasses that are in contact with the metal, determine the form and rate of deterioration.
20.8: Corrosion - Chemistry LibreTexts
WebCorrosion is a galvanic process by which metals deteriorate through oxidation—usually but not always to their oxides. For example, when exposed to air, iron rusts, silver tarnishes, and copper and brass acquire a bluish-green surface called a patina. Of the various metals subject to corrosion, iron is by far the most important commercially.

Forms of Corrosion – Corrosion
WebFeb 15, 2023 · The forms of corrosion described here use the terminology in use at NASA-KSC. There are other equally valid methods of classifying corrosion, and no universally-accepted terminology is in use. Keep in mind that a given situation may lead to several forms of corrosion on the same piece of material.
