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 ...
Corrosion engineering is an engineering specialty that applies scientific, technical, engineering skills, and knowledge of natural laws and physical resources to ...
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 ...
The results achieved by both these electronic corrosion inhibitor devices point to the need for further research and testing in order to better understand how these devices are able to generate a shift in the potential of the metal panels, i.e., a cathodic effect, in the absence of a continuous electrolytic path required to close the electrical ...
Also Abrams' water-cement ratio law. A law which states that the strength of a concrete mix is inversely related to the mass ratio of water to cement. As the water content increases, the strength of the concrete decreases. abrasion The process of scuffing, scratching, wearing down, marring, or rubbing away a substance or substrate. It can be intentionally imposed in a controlled process using ...
Cobalt-based γ′ structure was found in 2006, allowing the development of cobalt-based superalloys, which are superior to nickel-based superalloys in corrosion resistance. However, in the base (cobalt–tungsten–aluminum) system, γ′ is only stable below 900 °C (1,650 °F), and cobalt-based superalloys tend to be weaker than their Ni ...
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture.Rust consists of hydrous iron(III) oxides (Fe 2 O 3 ·nH 2 O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH) 3), and is typically associated with the corrosion of refined iron.
Stress corrosion cracking (SCC) is the embrittlement caused by exposure to aqueous, corrosive materials. It relies on both a corrosive environment and the presence of tensile (not compressive) stress. Sulfide stress cracking is the embrittlement caused by absorption of hydrogen sulfide. Adsorption embrittlement is the embrittlement caused by ...
