With thermal spraying, protective coatings are applied to the surfaces to protect them against external influences such as corrosion or wear and are also able to extend their field of application. Our PERFECT spray® combines wire arc spraying with a digital power source and exceeds the possibilities of classical wire arc spraying with higher efficiency and low maintenance.
Anyone in the winter out and about on the world’s ski slopes is familiar with the situation: if you are freezing you wear the wrong clothing. It is so to speak our protective coating. In a similar way, the thermal coating process affects the components. Using various thermal spraying methods, protective coatings are applied to the surfaces to protect them against external influences. In this way, components may become resistant for example against corrosion or wear, which not only may make them last longer, but additionally extend their field of application.
In thermal spraying, coating materials such as wires, powders or bars are fed to a spray gun or to a burner. The materials are heated and then accelerated into the direction of the component. In this way, the joined or fused particles achieve high speeds of up to 800 meters per second hitting the surface of the component. After the heat is transferred to the base material the particles solidify on the component’s surface where they form a layer. The spray coating, however, not only spreads on the surface but virtually joins to it. Depending on the desired coating thickness, this process is repeated.
