To provide conditions for subsequent coatings, removing all contaminants from the metal surface is necessary.
In conventional processes, abrasives or cleaning media used may remain on the surface or be carried over into the subsequent process steps. This can lead to coating defects, dust and particle inclusions, resulting in incorrect coatings.
Advantages
No beam and media cleaning during pretreatment with laser
Effective conditioning of metal parts
High area ratio possible
Coating with optimal adhesion (cross-sectional results of 0-1, resistance to corrosion aging)
