Environment Friendly Corrosion Inhibitors for Alloys or Metals
Naturally Occurring Wastes and Plants Corrosion is defined as the deterioration and consequent loss of metals or alloys by chemical or electrochemical reaction with the environment. Corrosion reduces the service life of the equipment causing heavy economic losses. There are certain chemicals which act as corrosion inhibitors that react with the surface of metal exposed to the environment and giving a certain level of protection. Corrosion inhibitors protect the metal by adsorbing themselves on the metallic surface by forming a layer between the metal and environment. Corrosion inhibitors are organic and inorganic compounds containing N, S, and O atom act as corrosion inhibitor through co-ordinate bonding but they are toxic to environment and human being and expensive as well. Nowadays, Emphases have been given to the development of eco-friendly corrosion inhibitors. Natural products are incredibly rich sources of naturally synthesized chemicals used in most of the applications. Some
