Surface engineering
Laser surface engineering and surface functionalization make it possible to create effects or generate new properties on all surface types.
The characteristics of the surface engineering process:

Benefits
- Various functionalities (modification of surface wettability, emissivity, colour, tribological and antibacterial properties)
- Process without material removal by remodelling technique
- Surface texture tailored to needed function
- Large area and/or 3D treatment
- Possibility of reproducing the functionalities on polymers by injection moulding

Performance
- Super-hydrophobicity / self-cleaning surface
(Contact angle >150°) - Hydrophilicity
(Contact angle < 30°) - Reflectance < 5% in the range from UV to near IR
- Reduction of bacteria proliferation (up to 98%)

Throughput
Up to several cm2.s-1 for depending on the process

Laser workstation
- Laser fs to ns
- From IR to UV
- Scanning systems

Surface finishing
Adaptable depending on the application by generation of self-organizing structures or by controlled etching
Process sheet

Areas of application
- Sensors
- Aeronautics
- Medical
- Household appliances
- Food packaging
- Energy
