| dc.description.abstract | Copper, brass, aluminum and steel are considerably used in many industries due to their good electrical and mechanical properties. Most industrial environments are highly aggressive and corrosive for metals and alloys which leads to their decay during use. This further leads to operating problems which can cause a partial or total shutdown of the process. Stoppage of the process for even a short time causes economic and financial losses. Due to high economic losses, protection from corrosion is the focus of many industries as well as scientific research. The use of different compounds which possess characteristics of the inhibitor is extensively examined over the years. Most compounds that show good inhibition efficiency are toxic and considered environmental pollutants. In recent years demands for environmental protection are high which lead to needing for finding new environmentally safe inhibitors of corrosion of metals and alloys. Amino acids are cheap for production, highly soluble in water, and can be produced in high purity. Amino acids also contain heteroatoms in their structure which makes them almost ideal candidates for green corrosion inhibitors in different aggressive solutions. Different amino acids were tested as corrosion inhibitors in many aggressive mediums and showed good results in inhibition efficiency. The action mechanism of amino acids is based on the adsorption of molecules of amino acids on the metal surface and the formation of the protective film which prevents further dissolution of metals. Often, amino acids react with metal ions through coordinative bonds and form complexes that protect the surface of the metal. Also, amino acids in combination with other compounds manifest a synergistic effect. The synergistic effect is detected in the combination of two amino acids and in the combination of amino acids and surfactants. Surfactants provide better adsorption of the molecules of the amino acids on the metal surface and lead to higher inhibition efficiency | |
