A group of specialists in thermal spraying. We handle various processes from arc spraying to pre-treatment and finishing!
It is a type of electric spray coating that generates an arc discharge (electric spark) between two metal wires, using the discharge energy to melt the wires. The wires are fed in accordance with the melting rate, and compressed air is used to atomize the molten metal, which is then continuously sprayed onto the substrate to form a film. Compared to flame spraying methods, it has a higher spraying capacity (amount of coating per unit time) and excellent adhesion to the substrate due to the spraying material being sufficiently melted at high temperatures. The power supply for the arc spraying device can be alternating current, but direct current is used for stability of the arc. Since the wires act as electrodes, the spraying materials are limited to electrically conductive materials.
