The utilization of metals and alloys has been on the increase due to rapid technological advancement and industrialization. Nevertheless, these widely used metallic materials are subject to degradation due to exposure to the environment. Several methods have been applied by scientists to address the problem of corrosion. One of the most successful methods to control metallic degradation remains the application of chemical inhibitors. Ionic liquids are renowned organic compounds with high adsorption abilities and exceptional properties which have drawn attention to their use as corrosion inhibitors. In contemporary years, different types of ionic liquids have been reported to showcase their effectiveness in protecting metallic surfaces from corrosive ions. This chapter discusses recent advancements in the utilization of highperformance ionic liquids as eco-friendly inhibitors in different corrosive environments, as documented in literature over the last three years.
