Thermal spray coatings are protective layers applied to surfaces to enhance their durability and resistance to wear, corrosion, and heat. This process involves heating materials, such as metals or ceramics, until they melt and then spraying them onto a substrate. The result is a strong bond that improves the surface properties of various components, including aerospace parts and industrial machinery. These coatings can be tailored to meet specific requirements, making them versatile for different applications. Common materials used in thermal spraying include aluminum, zinc, and ceramic, each chosen for their unique protective qualities. This technology is widely used in industries like automotive and energy.
