Thermal spraying is a process where coating materials are heated and melted, then atomized into fine particles by high-speed airflow. These particles are then sprayed onto the surface of the workpiece at high velocity, forming a strong coating layer. This process imparts various physical and chemical properties to the workpiece, including enhanced hardness, wear resistance, corrosion resistance, heat resistance, oxidation resistance, insulation, electrical conductivity, sealing, sterilization, and microwave radiation protection.
