  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]

    In North America, copper mining began with marginal workings by Native Americans. Native copper is known to have been extracted from sites on Isle Royale with primitive stone tools between 800 and 1600. [12] Copper metallurgy was flourishing in South America, particularly in Peru around 1000 AD; it proceeded at a much slower rate on other ...

  4. Pickling (metal) - Wikipedia

    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 aluminium alloys. [1] A solution called pickle liquor , which usually contains acid , is used to remove the surface impurities.

  5. 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 ...

  6. Benzotriazole - Wikipedia

    BTA is a weak acid with a pK a = 8.2 [3] [4] It is a very weak Brønsted base with pK a < 0. [4] Not only can it act either as an acid or base, it can also bind to other species, utilizing the lone pair electrons. Applying this property, the BTA can form a stable coordination compound on a copper surface and behave as a corrosion inhibitor. [6]

  7. 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 .
