Corrosion rate of any material decreases by adding a certain chemical compound known as corrosion inhibitor. Metals can be protected against the humid environment with help of this chemical. Various industries use these inhibitors to reduce loss of metal and consumption of acid. They are mostly available in spray form with lubricant or as penetrating oil. The selection of the right type of inhibitor depends on the material and corrosive agents.
Different Types of Corrosion Inhibitors
- Anodic Inhibitors: This type of corrosion inhibitor is applied to the metal surface in order to form a layer of protective oxide. Chromates, tungstate, molybdates are some of the examples of this type of corrosion inhibitor.
- Cathodic Inhibitors: The diffusion of any unwanted particles to the surface of metal is prevented through this type of inhibitor as it slows down cathodic reactions.
- Mixed Inhibitors: Both anodic and cathodic reactions are reduced with the application of this type of corrosion inhibitor. Silicates and phosphates ar`e some of its examples.
- Volatile Corrosion Inhibitors: The chemical is passed into the condenser tubes via steam to protect the closed environment from corrosion.
Applications of Corrosion Inhibitors
- Volatile type of inhibitor is used in the boilers to decrease the impact of acid.
- To avoid corrosion on copper surfaces, Benzotriazole is used.
- Inhibitors such as Anticor 70 and Ferrophos are mixed in paints to increase its durability on the walls.
- To prevent microbial corrosion, antiseptic like Benzalkonium chloride is utilized in oil field industry.
- Corrosion inhibitor is added to water treatment systems for preventing dilution of lead and copper in pipes.
