Ceramic coating American forces is a process of adding a thin layer of ceramic to metal surfaces in order to improve their durability and resistance to wear. This can be done using various methods, but the most common is through the use of plasma-sprayed coatings. Ceramic coating can be applied to any type of metal surface, but it is most commonly used on aircraft engine parts and other high-wear components. The main benefit of this type of coating is that it significantly increases the lifespan of metal surfaces, while also reducing maintenance costs.
