(metallurgy) Corrosive degradation of metal parts at the crevices left at rolled joints or from other forming procedures; common in stainless steel heat exchangers in contact with chloride-containing fluids or other dissolved corrosives. Also known as contact corrosion

How does phosphoric acid affect the corrosion resistance of stainless steel?
Phosphoric acid can decrease the corrosion resistance of stainless steel by promoting the formation of localized corrosion, such as pitting and crevice corrosion. This is due to the acid's ability to break down the protective passive film on the stainless steel surface, making it more susceptible to corrosion.
Explain the role played by dissolved oxygen in the general mechanism proposed to explain the various steps in crevice corrosion?
Dissolved Oxygen(usually between 20 - 60 ppm) reacts with H2O and the delocalized (conductive) electrons on the surface metal O2 + H2O + 4e- to form 4(OH)- ions that in turn draw the now charged (Fe2+) ions out into solution as 2Fe(OH)2...RUST
Abyss is to chasm as fissure is to?
Ah, what a lovely question! Just like how an abyss is a deep, vast space, a chasm is also a deep opening in the earth. Similarly, a fissure is like a narrow opening or crack, so the relationship between abyss and chasm is akin to fissure and crevice. Remember, each word paints a beautiful picture in our minds!

What are the list of corrosion of metals in seawater?
Corrosion of metals in seawater primarily includes galvanic corrosion, pitting corrosion, and crevice corrosion. Galvanic corrosion occurs when two dissimilar metals are in contact in the presence of an electrolyte, leading to accelerated corrosion of the more anodic metal. Pitting corrosion involves localized, small pits forming on the metal surface due to chloride ions, while crevice corrosion occurs in confined spaces where stagnant seawater can become more corrosive. Additionally, stress corrosion cracking can occur under tensile stress in a corrosive environment, further affecting metal integrity in seawater.
