The PVD coating process offers excellent possibilities in both the decorative and functional areas and stands as an abbreviation for “Physical Vapour Deposition”.
By bombardment with laser beams, magnetically deflected ions or electrons (sputtering) as well as by arc discharge (arc process), the material, which is called the target, is vaporized. Depending on the reactive gas composition, PVD coatings produce nitrides and carbides or mixtures of the same as layers, which offer very good scratch and wear resistance in addition to high hardness (>2000HV).
Arc evaporation and sputtering with different materials in this coating process result in surfaces with excellent properties and impressive colors. Furthermore, they are also very chemically and electrochemically inert, ensuring protection against a wide range of corrosive media.
Of course, the amount of atoms, ions or larger clusters in the vapor varies from process to process. Either ballistically or guided by electric fields, the vaporized material in the PVD coating process moves through the designated chamber and encounters the material to be coated.
