Using the flame as the heat source, the metal and non-metallic materials are heated to the melting state, and a fog flow is formed under the promotion of high-speed airflow, which is sprayed onto the substrate. When the injected tiny molten particles hit the substrate, plastic deformation occurs and the coating becomes a lamellar superposition deposit. This process is called flame spraying.
Flame spraying is a widely used process in spraying technology.Various pure metal, alloy and ceramic coatings can be prepared by flame spraying.
