Thermal spray coating is a process used to apply a protective layer to a surface. This technique involves heating materials, such as metals or ceramics, until they melt and then spraying them onto a substrate. The molten particles solidify upon contact, forming a strong bond that enhances the surface's durability and resistance to wear, corrosion, and heat. This method is widely used in various industries, including aerospace, automotive, and manufacturing. It can improve the lifespan of components like turbine blades and engine parts, making them more efficient and reliable. Thermal spray coatings can also be tailored to meet specific performance requirements.
