Human activities are becoming more complex and widespread, particularly the use of metal-based materials in everyday life and industry, resulting in increased corrosion that occurs and inhibits the process. Metal corrosion can be slowed by coating the metal with a corrosion inhibitor. Over the last decade, research into ionic liquids (ILs) as corrosion inhibitors has grown at an exponential rate. Metals are effectively inhibited by several cation ILs namely imidazolium, phosphonium, pyridazinium, benzimidazole, pyridinium, and others. ILs-based corrosion inhibitors are used to protect common metals such as carbon steel, copper, magnesium, stainless steel, and zinc. However, IL-based corrosion inhibitors are still used infrequently in industry. As a result, the purpose of this review paper is to demonstrate everything from research to the commercialization process in the industrialized world. The review paper goes into detail about the different types of ILs used as corrosion inhibitors; the mechanism of corrosion inhibition in immobilized fluids; the impact of turbulence on corrosion; the price of ILs in the future; the eco-friendly (the greenness) of ILs as corrosion inhibitors; and the industrial commercialization of ILs.
