After sandblasting, the workpiece is protected against corrosion. Using arc spraying, we apply a zinc-aluminum alloy.

Little deformation thanks to arc spraying (LDS)

An electric arc is generated between the workpiece and the spray wire. This melts the material of the spray arc, i.e. the zinc-aluminum alloy, at around 4000 ° C. Extremely small particles are created that are blown onto the workpiece at a constant speed.

With this process, the temperature of the workpiece remains below 100 ° C, which means that it is hardly deformed.

The layer thickness is normally around 60 μm.
