A corrosion inhibitor or anti-corrosive is a chemical compound added to a liquid or gas to decrease the corrosion rate of a metal that comes into contact with the fluid. [1] The effectiveness of a corrosion inhibitor depends on fluid composition and dynamics .
The first widescale use of VCIs can be traced to Shell's patent for dicyclohexylammonium nitrite (DICHAN), which was eventually commercialized as VPI 260. [3] DICHAN was used extensively by the US military to protect a wide variety of metallic components from corrosion via various delivery systems, VCI powder, VCI paper, VCI solution, VCI slushing compound, etc.
Fatty amines: These corrosion inhibitors are organic compounds that contain an amino group and an alkyl group. They act as cathodic inhibitors and form a protective layer on the metal surface.They work efficiently against corrosion brought about by carbon dioxide (CO2) and hydrogen sulfide (H2S). Also, ethoxylated amines are widely applied for ...
Corrosion control professionals find they do not work. [48] There is no peer reviewed scientific testing and validation supporting the use of the devices. In 1996 the FTC ordered David McCready, a person that sold devices claiming to protect cars from corrosion, to pay restitution and banned the names "Rust Buster" and "Rust Evader." [49]

Cosmoline is the genericized trademark for a common class of brown, wax-like petroleum-based corrosion inhibitors, typically conforming to United States Military Standard MIL-C-11796C Class 3. [1] They are viscous when freshly applied, have a slight fluorescence , and solidify over time with exposure to air.

In brief, corrosion is a chemical reaction occurring by an electrochemical mechanism (a redox reaction). [1] During corrosion of iron or steel there are two reactions, oxidation (equation 1), where electrons leave the metal (and the metal dissolves, i.e. actual loss of metal results) and reduction, where the electrons are used to convert oxygen and water to hydroxide ions (equation 2): [2]
