Nanotechnology in Corrosion Prevention: Toward Longer-Lasting Materials
By: Asst. Lecturer Shahad Ammar Hatem
Sustainable Development Goals (SDGs) Addressed:
Goal 9: Industry, Innovation and Infrastructure
Goal 12: Responsible Consumption and Production
Corrosion is a major issue in infrastructure, energy systems, and transportation, leading to significant economic and safety concerns. Nanotechnology offers advanced solutions through nano-coatings, corrosion inhibitors, and surface treatments.
Nanomaterials enhance barrier properties, improve adhesion, and provide self-healing capabilities. For example, nano-ceramics and carbon nanotubes embedded in protective coatings significantly reduce corrosion rates.
Additionally, nano-inhibitors can be incorporated into paints or greases to provide active and targeted corrosion protection. These technologies extend the lifespan of assets, reduce maintenance costs, and improve sustainability.
Despite cost and scalability issues, ongoing research is expanding the practical use of nanotechnology in corrosion protection, making materials more durable and efficient.
