2. Cathodic protection - Wikipedia

   en.wikipedia.org/wiki/Cathodic_protection

   Cathodic protection (CP; / k æ ˈ θ ɒ d ɪ k / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. [1] A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes ...

3. 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 ...

4. Galvanic corrosion - Wikipedia

   en.wikipedia.org/wiki/Galvanic_corrosion

   Another example is the cathodic protection of buried or submerged structures as well as hot water storage tanks. In this case, sacrificial anodes work as part of a galvanic couple, promoting corrosion of the anode, while protecting the cathode metal.

5. Association for Materials Protection and Performance

   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 ...

6. Galvanic series - Wikipedia

   en.wikipedia.org/wiki/Galvanic_series

   The unshaded bars indicate the location on the chart of those steels when in acidic/stagnant water ( like in the bilge ), where crevice-corrosion happens. Notice how the *same* steel has much different galvanic-series location, depending on the electrolyte it's in, making prevention of corrosion .. more difficult.

7. Electroplating - Wikipedia

   en.wikipedia.org/wiki/Electroplating

   Electroplating is widely used in industry and decorative arts to improve the surface qualities of objects—such as resistance to abrasion and corrosion, lubricity, reflectivity, electrical conductivity, or appearance.

8. Electrophoretic deposition - Wikipedia

   en.wikipedia.org/wiki/Electrophoretic_deposition

   The most common type of crosslinking chemistry in use today with cathodic products are based on urethane and urea chemistries. The aromatic polyurethane and urea type crosslinker is one of the significant reasons why many cathodic electrocoats show high levels of protection against corrosion. Of course it is not the only reason, but if one ...

9. Sacrificial metal - Wikipedia

   en.wikipedia.org/wiki/Sacrificial_metal

   A sacrificial metal is a metal used as a sacrificial anode in cathodic protection that corrodes to prevent a primary metal from corrosion or rusting. [1] It may also be used for galvanization. Equation
