  2. Corrosion inhibitor - Wikipedia

    en.wikipedia.org/wiki/Corrosion_inhibitor

    The effectiveness of a corrosion inhibitor depends on fluid composition and dynamics. Corrosion inhibitors are common in industry, and also found in over-the-counter products, typically in spray form in combination with a lubricant and sometimes a penetrating oil. They may be added to water to prevent leaching of lead or copper from pipes. [2]

  3. Benzotriazole - Wikipedia

    en.wikipedia.org/wiki/Benzotriazole

    Benzotriazole is an effective corrosion inhibitor for copper and its alloys by preventing undesirable surface reactions. It is known that a passive layer, consisting of a complex between copper and benzotriazole, is formed when copper is immersed in a solution containing benzotriazole.

  4. Volatile corrosion inhibitor - Wikipedia

    en.wikipedia.org/wiki/Volatile_corrosion_inhibitor

    The mechanism for copper begins the same as for steel, evolution of the inhibitor. Once at the copper surface however, the inhibitor will form a copper benzotriazole complex which is protective. [9] Vapor pressure is a critical parameter in VCI effectiveness. The most favorable range of pressure is 10 −3 to 10 −2 Pa at room temperature ...

    en.wikipedia.org/wiki/Pickling_(metal)

    Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, and rust or scale from ferrous metals, copper, precious metals and aluminum alloys. [1] A solution called pickle liquor , which usually contains acid , is used to remove the surface impurities.

  7. Metal deactivator - Wikipedia

    en.wikipedia.org/wiki/Metal_deactivator

    Salen is a typical metal-deactivator. Metal deactivators, or metal deactivating agents (MDA) are fuel additives and oil additives used to stabilize fluids by deactivating (usually by sequestering) metal ions, mostly introduced by the action of naturally occurring acids in the fuel and acids generated in lubricants by oxidative processes with the metallic parts of the systems.
