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.
Skydrol is a brand name of fire-resistant hydraulic fluid [1] used in aviation and aerospace applications. It is a phosphate ester-based fluid that is known for its excellent fire resistance and ability to withstand extreme temperature and pressure conditions.
Because electrolytically zinc-plated surfaces provide comparatively little corrosion protection, and in the case of galvanic zinc coatings on high-strength steel (e.g. category 10.9 and 12.9 high-strength bolts) there is a risk of hydrogen embrittlement, the industry needed a better corrosion protection system.
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.
With its big screen and optional keyboard and stylus, the Fire Max 11 gives the latest iPad a run for the money.
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]
Corrosion monitoring is the use of a corrator (corrosion meter) or set of methods [1] and equipment to provide offline or online information about corrosion rate expressed in mpy (mill per year). [ 2 ] - for better care and to take or improve preventive measures to combat and protect against corrosion .
