147 results about "Volatile corrosion inhibitor" patented technology

Volatile corrosion inhibitors (VCI) are a type of corrosion inhibitor that are used to protect ferrous materials and non ferrous metals against corrosion or oxidation where it is impractical to apply surface treatments. They slowly release chemical compounds within a sealed airspace that actively prevents surface corrosion. A typical application is to protect stored tools or parts inside bags, boxes or cupboards, one advantage of VCIs being that if the container is opened and reclosed, levels of inhibitor will recover.

Microencapsulated chemical(s), as water-soluble solid particles, are embedded in at least one the paint layers on the surface of a magnesium article used in an automobile. If the protective paint film is scratched or otherwise mechanically disturbed to expose the surface of the magnesium article the capsules will be ruptured. This will expose the encapsulated chemical(s) to ambient water enabling them to dissolve and form an aqueous solution capable of reacting with the exposed magnesium to form a protective passivating layer on the exposed magnesium to resist corrosion. In a second embodiment the encapsulated chemicals include a deliquescing compound for extraction of moisture from the atmosphere sufficient to induce dissolution of the passivating layer-forming chemical(s) and trigger the formation of the passivating layer in the absence of ambient water.

Supramolecular oxo-anion corrosion inhibitors

A corrosion inhibitor is described which includes several supramolecular oxo-anion compositions useful for preventing the propagation of pit corrosion on aluminum and aluminum alloys. The oxo-anion compositions preferably include soluble polymeric oxidic acids comprising combinations of molybdenum, phosphorous, tungsten, and silicon. These compositions are useful as corrosion inhibitors in high-moisture, corrosive environments, such as radiators and cooling systems. For low-moisture environments, these oxo-anion compositions can be reacted with a counter-ion, such as various metals, including, but not limited to the rear earth metals, to form a soluble salt. The salt can then be adsorbed onto a carrier, such as paint pigments, which can then be applied to the surfaces of aluminum and aluminum alloys. These surface adsorbates then become sparingly soluble and are gradually released over time in the presence of an aqueous corrosive agent so as to prevent propagation of pit corrosion.
