Vacuum Coating (Vacuum Metalizing)
Vacuum coating processes use vacuum technology to create a sub-atmospheric pressure environment and an atomic or molecular condensable vapor source to deposit thin films and coatings. The vapor source may be from a solid or liquid surface (physical vapor deposition - PVD, is the most common process), or from a chemical vapor precursor (chemical vapor deposition - CVD).
The 3 current used for deposition of metal layers in PVD (Physical Vapor Deposition) techniques:
(1) Evaporation (2) Sputtering (3) Ion Plating
Advantage:
• Most coatings have high temperature and good impact strength. With an additional clear abrasion resistant top coat, excellent abrasion resistance is also achieved (pass brasion Test ：24-48 hours & Salt Spray Test：24-72 hours).
• Ability to utilize virtually any type of inorganic coating material on an equally diverse group of substrates and surfaces using a wide variety of finishes.
• Vacuum process es are ecologically very clean, so more environmentally friendly than traditional coating processes such as electroplating and painting.
• Low outgassing
• Ecologically clean - no aggressive chemicals used
• Inorganic and completely non toxic
