What are the types of corrosion inhibitors?

Types of corrosion inhibitors:
  • Anodic inhibitors react with oxygen to form a thin film on the surface of the metal.
  • Cathodic inhibitors slow the cathodic reaction itself or limit the diffusion of reductive elements such as hydrogen or oxygen to the metal surface.

In this regard, what is corrosion inhibitor?

A corrosion inhibitor is a chemical compound that, when added to a liquid or gas, decreases the corrosion rate of a material, typically a metal or an alloy, that comes into contact with the fluid. The effectiveness of a corrosion inhibitor depends on fluid composition, quantity of water, and flow regime.

Subsequently, question is, what are the different inhibitors used to reduce corrosion rate? Some examples are chromates, nitrates, molybdates, and tungstate. These inhibitors slows down the cathodic reaction to limit the diffusion of reducing species to the metal surface. Cathodic poison and oxygen scavengers are examples of this type of inhibitor.

What are anodic inhibitors?

Anodic inhibitors are chemical substances that form a protective layer of oxide film on the surface of metal, causing resistance to corrosion. These inhibitors particularly alter the anodic reactions in a chemical cell, forcing the metallic surface into the passivation region.
