How nanotechnology works

Plasma treatment plants consist schematically of a vacuum chamber, a pumping system and a plasma generation system.

The workpieces are hooked to an aluminum frame (also called an antenna) and placed in the reaction chamber and the system is brought into vacuum. Once the necessary vacuum is reached, a radio frequency is applied to the antenna and thus to the parts to be treated, generating plasma.

Low pressure plasma systems represent an inherently 'clean' series of surface treatments as they operate with very low quantities of reagents and consequently minimal formation of by-products. In fact, the reaction by-products are so minimal that, once absorbed by the pumps, no recovery or disposal is required.

The strengths of plasma treatments

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.
