  2. Corrosion - Wikipedia

    en.wikipedia.org/wiki/Corrosion

    Corrosion removal should not be confused with electropolishing, which removes some layers of the underlying metal to make a smooth surface. For example, phosphoric acid may also be used to electropolish copper but it does this by removing copper, not the products of copper corrosion.

  3. Liquid metal embrittlement - Wikipedia

    en.wikipedia.org/wiki/Liquid_metal_embrittlement

    Liquid metal embrittlement (also known as LME and liquid metal induced embrittlement) is a phenomenon of practical importance, where certain ductile metals experience drastic loss in tensile ductility or undergo brittle fracture when exposed to specific liquid metals.

  4. Embrittlement - Wikipedia

    en.wikipedia.org/wiki/Embrittlement

    Liquid metal embrittlement (LME) is the embrittlement caused by liquid metals. Metal-induced embrittlement (MIE) is the embrittlement caused by diffusion of atoms of metal, either solid or liquid, into the material. For example, cadmium coating on high-strength steel, which was originally done to prevent corrosion.

  5. Liquidmetal - Wikipedia

    en.wikipedia.org/wiki/Liquidmetal

    In a demonstration, a metal sphere dropped on amorphous steel bounced significantly longer than the same metal sphere dropped on crystalline steel. [4] The lack of grain boundaries in a metallic glass eliminates grain-boundary corrosion—a common problem in high-strength alloys produced by precipitation hardening and sensitized stainless steels.

  6. Galvanic corrosion - Wikipedia

    en.wikipedia.org/wiki/Galvanic_corrosion

    In other cases, such as mixed metals in piping (for example, copper, cast iron and other cast metals), galvanic corrosion will contribute to accelerated corrosion of parts of the system. Corrosion inhibitors such as sodium nitrite or sodium molybdate can be injected into these systems to reduce the galvanic potential. However, the application ...

  7. Metal-induced embrittlement - Wikipedia

    en.wikipedia.org/wiki/Metal-induced_embrittlement

    Metal-induced embrittlement (MIE) is the embrittlement caused by diffusion of metal, either solid or liquid, into the base material. Metal induced embrittlement occurs when metals are in contact with low-melting point metals while under tensile stress. The embrittler can be either solid or liquid (liquid metal embrittlement).

  8. High-temperature corrosion - Wikipedia

    en.wikipedia.org/wiki/High-temperature_corrosion

    High-temperature corrosion is a mechanism of corrosion that takes place when gas turbines, diesel engines, furnaces or other machinery come in contact with hot gas containing certain contaminants. Fuel sometimes contains vanadium compounds or sulfates, which can form low melting point compounds during combustion.

  9. Environmental stress fracture - Wikipedia

    en.wikipedia.org/wiki/Environmental_stress_fracture

    Corrosion during service in moist environments generates hydrogen, part of which may enter the metal as atomic hydrogen (H •) and cause embrittlement. Presence of a tensile stress, either inherent or externally applied, is necessary for metals to be damaged. As in the case of stress corrosion cracking, hydrogen embrittlement may also lead to ...
