Advances in corrosion inhibition materials and technologies: A review

Abstract

In view of the fact that corrosion costs large sums of money and touches countless facets of human activities, every possible effort needs to be made to find ways to stop it from starting. In this regard inhibition of corrosion has become a thriving commercial activity, worldwide. Much research has been devoted to discovering newer strategies to inhibit corrosion with concomitant improvements in corrosion inhibition materials. This review will focus on the advances in materials and technologies for corrosion inhibition, with particular attention to the evolution of technologies and materials prior to the advent of coatings, the exploitation of 'green methods' which use anti-corrosion materials, which protect materials without fouling the environment; and the present and projected role of nanotechnology in inhibition of corrosion. This review brings together the collected wisdom of several disciplines. The latter addressed and/or are continuing to address the need for cost-effective materials to protect strategic metals used in the domestic and industrial sectors of most countries. The scope for improving the quality of materials, required for shielding these metals from the ravages of degrading agents, present in the environments of most cities, is lucidly articulated.

Recent Trends in the Characterization and Application Progress of Nano-Modified Coatings in Corrosion Mitigation of Metals and Alloys

“…Metals are employed as basic materials or fundamental materials in enterprises and several other fields due to their many appealing features, including electrical and thermal conductance, increased boiling and melting ranges, greater compressive strength, greater mass-to-volume fraction, and flexibility. Electrochemical interactions involving metals and their surroundings occur when metals engage with their environment [40,41]. A variety of methods are employed to slow the corrosion rate (C R ), including metallic surface treatment, environmental alterations, the application of CIs, and changes in pH and utilization of coatings.…”

“…Therefore, one way to prevent early wear and corrosion is by carrying out a surface treatment process, which is, coating other metals or oxides on the surface of the metal [4]. Steels are coated with anticorrosion materials, such as Galvalume, galvanized coating and organic/inorganic inhibitor coatings [4][5][6][7][8][9][10]. The different between galvalume and galvanized coating, that is, Galvalume coating is a coating composed of aluminum and zinc; however, Galvanized coating is a coating that is almost 100% made of zinc or with a little addition of silicon.…”

“…In the other methods of corrosion protection, phosphate conversion coating is a chemical treatment with excellent binding performance due to chemical bonding between the coating and the matrix metal. Zinc, manganese and iron phosphate coatings are often used in metal coating [8][9][10][11][12]. In traditional phosphating treatment, the steel workpieces are usually treated with various catalysts at high temperatures to obtain a suitable coating, which is not friendly to the environment and human health [12].…”
