Physical vapor deposition (PVD) describes a variety of vacuum deposition methods that can be used to produce thin films and coatings. 

 

PVD coatings where a solid material is vaporized in a vacuum chamber and deposited onto a target material.  It is used to change the surface properties of the object to be coated, Where new optical characteristics are needed. By varying the gases and duration of the process, a range of colors is produced by Physical Vapour Deposition on stainless steel.

 

The resulting colored stainless steel product can appear as brass, bronze, copper, and other metals or alloys. This PVD-colored stainless steel can be used as per your requirements.
