Corrosion 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 ...
A corrosive material is a liquid or solid that causes full thickness destruction of human skin at the site of contact within a specified period of time. A liquid that has a severe corrosion rate on steel or aluminum based on the criteria in 49CFR 173.137(c)(2) is also a corrosive material .
Corrosion engineering is an engineering specialty that applies scientific, technical, engineering skills, and knowledge of natural laws and physical resources to ...
The Corrosive and Explosive Substances and Offensive Weapons Act 1958 (Malay: Akta Bahan-Bahan Kakisan dan Letupan dan Senjata Berbahaya 1958) is a Malaysian law which enacted to provide certain penalties relating to the unlawful possession of corrosive and explosive substances and the carrying of offensive weapons.
Crevice corrosion refers to corrosion occurring in occluded spaces such as interstices in which a stagnant solution is trapped and not renewed. [1] These spaces are generally called crevices. Examples of crevices are gaps and contact areas between parts, under gaskets or seals, inside cracks and seams, spaces filled with deposits and under ...
enhanced corrosion of the material, if the corrosion rate of the material depends on the thickness of the oxide layer. The mechanism of erosion corrosion, the materials affected by it, and the conditions when it occurs are generally different from that of flow-accelerated corrosion , although the latter is sometimes classified as a sub-type of ...
Corrosion under insulation (CUI) is a severe form of localized external corrosion that occurs in carbon and low alloy steel equipment that has been insulated. This form of corrosion occurs when water is absorbed by or collected in the insulation. The equipment begins to corrode as it is exposed to water and oxygen.
Intergranular corrosion is a concern especially for alloys with high content of copper. Other kinds of alloys can undergo exfoliation as well; the sensitivity of cupronickel increases together with its nickel content. A broader term for this class of corrosion is lamellar corrosion.
