6 - Corrosion inhibitors for basic environments

Abstract

Nowadays, corrosion control of metals, whose area of use is increasing day by day, has technical, economic, and environmental importance. The most preferred of the various methods used to prevent corrosion is the addition of a suitable inhibitor to the environment. Corrosion inhibitors are widely used as they increase the service life of metals by forming a layer over the metallic substrate. Corrosion inhibitors are used in acidic, basic, and neutral environments. One of the most important factors affecting the corrosion behavior of metals in the environment is the pH value of the medium. It is known that metals which are generally corroded in acidic environments, are less corroded in alkaline environments. In this chapter, there are corrosion inhibitors used in alkaline environments. Accordingly, studies and research carried out on organic, inorganic, and green corrosion inhibitors used in basic environments have been organized in recent years.
