Plasma spraying is a thermal spray coating process that uses a high-temperature plasma jet to melt and propel materials onto a surface. This technique is commonly used to apply coatings for wear resistance, corrosion protection, and thermal insulation. The materials, often in powder form, are injected into the plasma jet, where they are heated to a molten state before being sprayed onto the target surface. The process can be performed in various environments, including vacuum or atmospheric conditions, depending on the desired coating properties. Plasma spraying is widely utilized in industries such as aerospace, automotive, and medical devices to enhance the performance and longevity of components.
