Progress of Polymer Nanocomposite Coating in the Industrial Sector: An Overview

Corrosion and tribology are surface processes that occur on the outer layer of materials. Modifying surfaces of materials without changing their internal properties is an efficient method for reducing corrosion, friction, and wear in engineering applications. The progress in nanotechnology allows for the easy development of surface protective coatings using nanoparticles to investigate their effectiveness in reducing chemical and physical damage to surfaces. Surface protection improves the performance and extends the operational lifespan of industrial machinery components. The automotive, aerospace, electrical, water electrolysis, seawater condensers and tubes, and energy generating industries are among the many areas where this coating finds tremendous use. This paper provides an analysis of different types of newly created nanostructured coatings, including their methods of manufacture, corrosion characteristics, and tribological performance. It presents information on the progress of nanostructured coatings, namely nanocomposite coatings with metal and polymer matrices. The present review is intended to report a series of works aimed to prevent corrosion by nano-composite coatings.
