Аннотация: Corrosion is a natural and detrimental process that significantly impacts the durability and performance of materials, particularly metals, across various industries, including construction, automotive, aerospace, and marine engineering. Traditionally, corrosion prevention has relied on coatings, inhibitors, and surface treatments. However, the recent advent of nanotechnology has introduced innovative solutions that promise enhanced efficiency and sustainability. Nanomaterials, with their unique properties at the nanoscale, provide superior corrosion resistance, self-healing capabilities, and environmental compatibility. This paper explores the various nanotechnology applications used to combat corrosion, including the use of nanoparticles, nanostructured coatings, and self-healing materials. Through an in-depth examination of the mechanisms, materials, and real-world applications, the paper highlights the potential benefits of nanotechnology in corrosion prevention. Despite the promising advancements, challenges related to cost, scalability, and environmental impact remain. The future of nanotechnology in corrosion control holds great promise, with continuous research pushing the boundaries of material science.
