Decorative PVD

pdv decorativo

PVD (Physical Vapor Deposition) is a high adhesion thin ceramic coating performed in a highly ionized plasma deposition process in a vacuum chamber, where the temperatures can vary between 150° and 500°C. The high temperatures allow to obtain coatings with high purity, being chemically inert and biocompatible.

Decorative PVD coatings maintains the original finish without altering the appearance of the parts and assigning them a controlled thickness between 0.8 and 1.5 μm. Their application gives them greater strength and durability, increasing the product life.

DECORATIVE PVD APPLICATION PROCESS

The deposition of the decorative PVD coatings is applied through a cathodic arc consisting of the evaporation of the material to be used as coating (present in the targets) through a high power electric arc. It involves the deposition of Zirconium, Titanium, Chromium or other combinations of metal ions, with reactive gases.

The material to be deposited passes from its solid state to the gaseous state, condensing onto the substrate material of the part to be coated, forming a thin film of PVD coating (thickness between 0.8 and 1.5 μm)

They can also be applied through Sputtering deposition which consists of vaporizing particles from a target surface. The material to be deposited is on the targets attached to a cathode, and the substrate is connected to an anode. A rare gas, usually Argon, bombards the targets and the impact of their ions causes their surface atoms to be ejected. These atoms are transported by plasma to the surface to be coated and where a uniform and uniform coating film is to be condensed over several layers.
