"Physical Vapour Deposition" is the process we shorten to PVD. It is a state of the art development which deposits molecules of very hard wearing metals on to a selected surface. This process lends itself well to exterior hardware (such as an entry door-set or bathroom & kitchen fixtures) or items that will be subjected to a great deal of wear, either physical or from the elements.
The microscopic layer that is produced will protect the brass from oxidation, abrasion and wear found under normal use. Minimal maintenance is required simply wiping over with a damp cloth is normally sufficient.
Physical Vapor Deposition (PVD) comprises a group of surface coating technologies used for decorative coating, tool coating, and other equipment coating applications. It is fundamentally a vaporization coating process in which the basic mechanism is an atom by atom transfer of material from the solid phase to the vapor phase and back to the solid phase, gradually building a film on the surface to be coated. In the case of reactive deposition, the depositing material reacts with a gaseous environment of co-deposited material to form a film of compound material, such as a nitride, oxide, carbide or carbonitride.
PVD is a desirable alternative to electroplating and possibly some painting applications because it generates less hazardous waste and uses less hazardous materials (i.e., no plating baths). PVD can be applied using a wide variety of materials to coat an equally diverse number of substrates using any of the three basic PVD technologies to deposit a number of desired finishes of variable thickness with specific characteristics.
PVD coatings are sometimes harder and more corrosion resistant than coatings applied by the electroplating process. Most coatings have high temperature and good impact strength, excellent abrasion resistance and are so durable that protective topcoats are almost never necessary.
- Ability to utilize virtually any type of inorganic and some organic coating materials on an equally diverse group of substrates and surfaces using a wide variety of finishes.
- More environmentally friendly than traditional coating processes such as electroplating and painting.
- More than one technique can be used to deposit a given film.
