  2. Cathodic protection - Wikipedia

    en.wikipedia.org/wiki/Cathodic_protection

    The usual technique for concrete buildings, bridges and similar structures is to use ICCP, [30] but there are systems available that use the principle of galvanic cathodic protection as well, [31] [32] [33] although in the UK at least, the use of galvanic anodes for atmospherically exposed reinforced concrete structures is considered experimental.

    Both the legacy NACE and SSPC organizations were ANSI-accredited standards developers, which AMPP plans to continue.The merged standards program includes 25 standing standards committees that develop technical standards for industries including cathodic protection, coatings, defense, highways and bridges, rail, maritime, oil and gas, power and utilities, research and testing, tanks and ...

    Corrosion prevention measures, including Cathodic protection, designing to prevent corrosion and coating of structures fall within the regime of corrosion engineering. However, corrosion science and engineering go hand-in-hand and they cannot be separated: it is a permanent marriage to produce new and better methods of protection from time to time.

  5. Galvanic anode - Wikipedia

    en.wikipedia.org/wiki/Galvanic_anode

    A galvanic anode, or sacrificial anode, is the main component of a galvanic cathodic protection system used to protect buried or submerged metal structures from corrosion. They are made from a metal alloy with a more "active" voltage (more negative reduction potential / more positive oxidation potential) than the metal of the structure. The ...

    Example of flat piece of concrete having dislodged with corroded rebar underneath, Welland River bridge across Queen Elizabeth Way in Niagara Falls, Ontario. The expansion of the corrosion products (iron oxides) of carbon steel reinforcement structures may induce internal mechanical stress (tensile stress) that cause the formation of cracks and disrupt the concrete structure.

    They act as anodic inhibitors and form a protective layer on the metal surface (Figure 5). [9] [10] Figure 5. Example of benzoazoles and triazoles. Polymers: Polymers are large molecules used in the petroleum industry as corrosion inhibitors. These polymers can adsorb onto the metal surface and form a protective coating.

  9. Stress corrosion cracking - Wikipedia

    en.wikipedia.org/wiki/Stress_corrosion_cracking

    Cathodic Protection: Cathodic protection is a technique used to protect metals from corrosion by applying a small electrical current to the metal surface. This technique can also help prevent SCC by reducing the corrosion potential of the metal. [7] Environmental Controls: Controlling the environment around the metal can help prevent SCC.
