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 .
Anodic inhibitors and cathodic inhibitors are the two main categories of corrosion inhibitors. While cathodic inhibitors act as catalysts to slow down corrosion, anodic inhibitors protect metal surfaces by acting as physical barriers. They can also be divided into organic and inorganic corrosion inhibitors based on their chemical composition. [1]
Coatings - The use of VCIs as alternative corrosion inhibitor technologies in coating is not a new concept. In the last few years, however, with growing environmental pressure to reduce the use of traditional inhibitors containing heavy metals, they have gained in popularity. Since VCI particles have a polar attraction to the metal substrate ...
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.
Lithium molybdate is used as corrosion inhibitor in LiBr (Lithium bromide) absorption chiller for industrial central air conditioning.It is manufactured and shipped as either a colorless, transparent fluid or a white crystal powder.
The purpose of the HF is to act as a corrosion inhibitor by forming a metal fluoride layer on the surface of the storage vessels. Water content of RFNA [ 7 ] To test the water content, a sample of 80% HNO 3 , 8–20% NO 2 , and the rest H 2 O depending on the varied amount of NO 2 in the sample.
The protective effect of chromate coatings on zinc is indicated by color, progressing from clear/blue to yellow, gold, olive drab and black. Darker coatings generally provide more corrosion resistance. [11] The coating color can also be changed with dyes, so color is not a complete indicator of the process used.
