Corrosion is the natural deterioration of materials, particularly metals, due to chemical reactions with their environment, such as oxidation or exposure to moisture, chemicals, and gases. This can weaken structures and equipment, leading to significant maintenance costs. Advanced coating applications are used to protect materials from corrosion by creating a barrier between the surface and the harmful elements. These coatings include paints, galvanization, and more high-tech solutions like powder coatings, polymer-based coatings, and nanocoatings. Advanced coatings improve the longevity, performance, and durability of materials, especially in industries like aerospace, automotive, and marine, where corrosion resistance is critical.
