# Metallizing

New materials, complex areas of application, advances in electronics, mechanics and electrical engineering: nowadays metal parts are exposed to extreme stresses. A surface treatment is therefore essential in many cases.

After [sandblasting](/competencies/surface-handling/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.
