http://corrosion-doctors.org/Forms-selective/dealloy.htm WebGraphitic corrosion of gray cast iron, whereby a brittle graphite skeleton remains following preferential iron dissolution is a further example of selective leaching. The term "graphitization" is commonly used to identify this form of corrosion but is not recommended because of its use in metallurgy for the decomposition of carbide to graphite.
WebGraphitic corrosion is selective leaching of iron, from grey cast iron, where iron is removed and graphite grains remain intact. Affected surfaces develop a layer of graphite, rust, and metallurgical impurities that may … WebAug 1, 1999 · Graphitic corrosion is a form of de-alloying or selective leaching that occurs in cast iron material.

WebDec 8, 2024 · Gray iron, or gray cast iron as it is also called, is most susceptible to graphitization. The process of graphitization separates the alloy, creating free carbon (also known as graphite), which clumps together. Graphitization occurs when the alloy is exposed to high temperatures (at least 800°F/ 426°C) for a prolonged period of time.
