Water Line Corrosion Wikipedia
The waterline is the line where the hull of a ship meets the surface of the water.
Water line corrosion wikipedia. Water cooling is a method of heat. La corrosion désigne l altération d un matériau par réaction chimique avec un oxydant le dioxygène et le cation h en majorité. Korrosion von lateinisch corrodere zersetzen zerfressen zernagen ist aus technischer sicht die reaktion eines werkstoffs mit seiner umgebung die eine messbare veränderung des werkstoffs bewirkt. This article may be in need of reorganization to comply with wikipedia s layout guidelines.
In the most common use of the word this means. Flow accelerated corrosion fac also known as flow assisted corrosion is a corrosion mechanism in which a normally protective oxide layer on a metal surface dissolves in a fast flowing water. September 2018 learn how and when to remove this template message learn how and when to remove this template message cooling tower and water discharge of a nuclear power plant. The driving power for pitting corrosion is the depassivation of a small area which becomes anodic while an unknown but potentially vast area becomes cathodic leading to very localized galvanic corrosion.
Il faut en exclure les effets purement mécaniques cela ne concerne pas par exemple la rupture sous l effet de chocs mais la corrosion peut se combiner avec les effets mécaniques et donner de la corrosion sous contrainte et de la fatigue corrosion. Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide hydroxide or sulfide. It is probably the second most common cause of copper tube failures behind type 1 pitting which is also known as cold water pitting of copper tube. Corrosion engineering is the field dedicated to controlling and preventing corrosion.
Galvanic 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 a similar galvanic reaction is exploited in primary cells to generate a useful electrical voltage to power portable devices. Korrosion kann zu einer beeinträchtigung der funktion eines bauteils oder systems führen. Pitting corrosion or pitting is a form of extremely localized corrosion that leads to the creation of small holes in the metal. It is the gradual destruction of materials usually a metal by chemical and or electrochemical reaction with their environment.
This creates a differential of the amount of oxygen in contact with the material s surface above and below the waterline and results in a corrosive reaction. Specifically it is also the name of a special marking also known as an international load line plimsoll line and water line positioned amidships that indicates the draft of the ship and the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain. Fac often affects carbon steel piping carrying. Eine durch lebewesen verursachte korrosion wird als biokorrosion bezeichnet.
Copper water tubes copper tubes have been used to distribute drinking water within buildings for many. The underlying metal corrodes to re create the oxide and thus the metal loss continues. Please help by editing the article to make improvements to the overall structure. Waterline corrosion occurs when one portion of a base material is submersed in the water and another portion is in contact with the air.
