Abstract
In the aerospace and defense industries, nanotechnology coatings have become essential facilitators for improving material performance. Usually less than 100 nm thick, these incredibly thin, multipurpose layers provide better defense against environmental stresses, corrosion, wear, and thermal deterioration than traditional coatings. Special physicochemical characteristics of materials at the nanoscale allow for revolutionary features like thermal insulation, radar stealth, self-healing, and smart sensing. To improve substrate longevity and operating efficiency, this review methodically looks at several important classes of nano-coatings, such as smart nanocontainers, carbon nanotube-reinforced systems, polymer-based nanoparticles, and barriers formed from graphene. Critical characterization techniques including SEM-EDS mapping, EBSD, and XRD for nanoscale structural evaluation are covered alongside advanced production techniques like atomic layer deposition, chemical vapor deposition, and sol-gel processing. Along with a candid evaluation of the present constraints
about durability, scalability, and environmental safety, the strategic applications of nano-coatings across key aerospace and defense materials—aluminum alloys, titanium, stainless steels, and composites—are also highlighted. This article offers a thorough understanding of the revolutionary potential of nanotechnology coatings for next-generation aerospace and defense systems by placing both innovations and difficulties in context.
