Nanostructured Coatings in Aerospace and Automotive Industries

Abstract

Nanostructured coatings have emerged as a revolutionary advancement in surface engineering, offering enhanced mechanical, thermal, and chemical properties essential for high-performance applications in the aerospace and automotive industries. By manipulating materials at the nanoscale, these coatings provide superior corrosion and wear resistance, thermal stability, and multifunctional capabilities such as self-cleaning, anti-icing, and sensing. In aerospace, nanocoatings improve engine efficiency, protect critical components from extreme environmental conditions, and contribute to weight reduction, directly impacting fuel consumption and operational costs. Similarly, the automotive sector benefits from nanostructured coatings through improved durability, scratch resistance, reduced friction, and environmentally friendly formulations that align with sustainability goals. Despitethese advantages, challenges related to scalable manufacturing, cost-effectiveness, environmental and health safety, and evolving regulatory landscapes remain. This paper reviews the fundamental properties, fabrication techniques, and key applications of nanostructured coatings in both industries, highlighting current innovations and practical implementations. It also addresses the limitations and emerging trends, including the integration of smart functionalities and digital technologies to optimize coating performance and lifecycle management. By providing a comprehensive overview, this work aims to inform stakeholders on leveraging nanostructured coatings to enhance product performance, safety, and sustainability, while navigating the complexities of  commercialization and regulation. The future of nanocoatings is poised for growth through multidisciplinary collaboration, sustainable development, and technological integration, promising significant contributions to the advancement of aerospace and automotive technologies.
