Electric arc

Electric arc spraying is a fusion of a material by means of an electric arc maintained between two polarized wires. The resulting droplets are then propelled onto the part to be coated by a gaseous jet (compressed air or other specific gas).

The projection equipment used is a manual or automatic gun mounted on a robot or a rigid mechanized system.

It is the most economical among all the thermal spraying techniques for metals and their alloys with high deposition rates.

• Arc voltages between 25 and 40 V
• Intensities ranging from 100 to 500 A
• Particle speed: ±150m/s
• Arc temperature: 4000°C/6000°C
• High deposit speed: 8-20kg/h

• Particularly useful for overlays
• Suitable for applying thick coatings on large surfaces
• Portable technology for on-site application
