Corrosion Inhibitor

A corrosion inhibitor is a chemical that is used in a certain atmosphere, including air or water, to slow down the rate of corrosion of the metal exposed to that atmosphere. Corrosion inhibitor, or CI, is an acronym.

 

What is a Corrosion Inhibitor?

 

A corrosion inhibitor is a chemical substance that can be added to liquids or gases and is employed to slow down the rate of corrosion of a certain material (often a metal).

The application of a coating to the metal’s surface that serves as a passivation layer and prevents access to the metal’s surface is one way to stop corrosion.

 

Various Corrosion Inhibitor Types

 

Depending on how they resist corrosion on the metal, corrosion inhibitors can be divided into four broad categories. These kinds include

  • Cathodic Inhibitor
  • Anodic Inhibitor
  • Mixed Inhibitor
  • Volatile Corrosion Inhibitor

 

Uses of Corrosion Inhibitors

 

There are numerous uses for corrosion inhibitors in business, industrial, and process settings. The following list includes a few of these applications.

 

  • Metals can avoid rusting and anodic corrosion by using corrosion inhibitors. This is often accomplished by covering the metal surface with a layer of chromate.

 

  • In order to react with dissolved oxygen in the environment and aid prevent cathodic corrosion, oxygen scavengers can be used as CIs.

 

  • Fuel pipeline corrosion and rusting must be avoided at all costs. In order to secure these pipelines and lower the likelihood of accidents, CIs are crucial.

 

  • Heating system metal pipes are vulnerable to corrosion. CIs are crucial for protecting these pipes as well.
