Corrosion Inhibition Using Hydrogen Evolution Approach in Acidic Medium

Abstract

This paper provides an outline of related literatures in which scientists and researchers used different types and procedure of corrosion inhibitors to reduce corrosion that takes place in various equipment made of alloys or metals. Different chemical inhibitors were used to reduce the rate of corrosion in various alloys. The inhibition rates ranged between 30-80% in acidic environments with different molar concentrations. Using a quantitative approach (including basic equations, explained and derived, and illustrative problems), this volume discusses the basic thermodynamic and electrochemical principles that cause corrosion and treats practical corrosion problems and methods of protection and prevention. The use of inhibitors for the control of corrosion of metals and alloys which are in contact with aggressive environment is an accepted practice. The emphasis is on HCl solutions, lower-grade steels, and elevated temperatures. This review is also devoted to corrosion inhibitor formulation design – mixtures of corrosion inhibitors with (mainly) surfactants, solvents, and intensifiers to improve the effectiveness of individual compounds at elevated temperatures. The information presented in this review is useful for diverse industrial fields, primarily for the well acidizing procedure, and secondly for other applications where corrosion inhibitors materials are needed.
