The strengths of surface treatments with low-pressure plasmas can be summarized as follows:
- Possibility of exposing any material without thermodegradation.
- Dry process that does not require solvents, which are often hazardous to the environment.
- Negligible release of unwanted by-products.
- Modification of the surface without altering the general properties of the product.
The stages of machining can be distinguished into material loading, machining and finally product unloading. The loading and unloading phases can be managed by personnel or by automatic systems.
The coating appears as a compact coating with thicknesses well below one micron.
