Examples of corrosion in the following topics:
-
- Corrosion is commonly discussed in reference to metals, which corrode electrochemically.
- In a corrosion system, the metal being corroded acts as the anode of a short-circuited electrochemical cell:
- How susceptible a particular metal is to corrosion can be determined by its reduction potential.
- Corrosion is a common nuisance with real impact.
- This photo of the Nandu River Iron Bridge in Hainan, China displays evidence of damage by corrosion.
-
- Preventing corrosion reduces both the economic and safety-related damages associated with the process.
- It follows, then, that we can prevent corrosion by removing one of these essential conditions.
- Corrosion of the sacrificial zinc results in its oxidation; the iron is reduced, which renders it cathodic and inhibits its corrosion.
- As long as the tin coating remains intact, corrosion is not possible.
- Anodization is another surface treatment that protects against corrosion.
-
- Titanium, chromium and manganese are 3d transition metals notably used to add corrosion-resistance, durability, and lightness to steel.
- It has a low density, is corrosion-resistant, and has a silver color.
- Stainless steel is highly resistant to corrosion and discoloration.
- Manganese phosphating is used as a treatment for rust and corrosion on steel.
- Titanium is one of the least dense, strong, and corrosion-resistant elements.
-
- A perfect disinfectant would offer full microbiological sterilisation, without harming humans and would also be non-corrosive.
- It would also be inexpensive and non-corrosive.
- Some disinfectants have a wide spectrum and kill many different types of microorganisms, while others kill a smaller range of disease-causing organisms but are preferred for other instances (they may be non-corrosive, non-toxic, or inexpensive).
-
- For example, aluminum foil develops a thin skin of Al2O3 (called a passivation layer) that protects the foil from further corrosion.
- Two independent pathways for corrosion of elements are hydrolysis and oxidation by oxygen.
- The combination of water and oxygen is even more corrosive.
- As mentioned above, a well-known example is aluminum foil, which is coated with a thin film of aluminium oxide that passivates the metal, slowing further corrosion.
-
- They live in the water-fuel interface of the water droplets, form dark black/brown/green, gel-like mats, and cause microbial corrosion to plastic and rubber parts of the aircraft fuel system by consuming them, and to the metal parts by the means of their acidic metabolic products.
- P. aeruginosa is capable of growth in diesel and jet fuel, where it is known as a hydrocarbon-using microorganism (or "HUM bug"), causing microbial corrosion. [3] It creates dark, gellish mats sometimes improperly called "algae" because of their appearance.
-
- For orthopedic uses, metals such as tantalum or titanium are often used because these metals exhibit high tensile strength and corrosion resistance, along with excellent biocompatibility.
-
- The mucuous membranes are especially important for protecting the urethral tissues from the corrosive effects of urine.
-
- Sulfate-reducing bacteria oxidize this hydrogen, creating hydrogen sulfide, which contributes to corrosion.
- Hydrogen sulfide from sulfate-reducing bacteria also plays a role in the biogenic sulfide corrosion of concrete, and sours crude oil.
-
- Durability in the concrete environment, irrespective of corrosion or sustained stress
- Corrosion, along with freeze and thaw cycles, may damage poorly designed or constructed reinforced concrete.
