Non-sacrificial coatings are protective layers applied to surfaces to prevent corrosion and wear without being consumed in the process. Unlike sacrificial coatings, which corrode instead of the underlying material, non-sacrificial coatings maintain their integrity over time, providing long-lasting protection. These coatings can be made from various materials, including polymers and ceramics. These coatings are commonly used in industries such as aerospace, automotive, and marine to enhance the durability of components. They can be applied to metals, plastics, and other substrates, offering resistance to environmental factors like moisture, chemicals, and UV radiation.
