Although the two phrases literally differ by only one word, the difference between them is actually great. When it comes to this phrase, many people compare it to chemical vapor deposition (CVD). Physical vapor deposition (PVD) is a widely used thin film fabrication technique. There are many choices and the price is affordable, compared to pure gold or other pure metals. PVD can coat gold, brass, rose gold, silver white, black, smoky, copper, brown, purple, blue, burgundy, bronze and other colors on stainless steel, copper, zinc alloy and other metals. PVD is now quite popular in the hardware field, and many of the world’s leading hardware manufacturers have begun to develop PVD products and mass production. PVD technology is widely used in the processing of door and window hardware, lamps, jewelry, handicrafts, and other decorative products. The physical vapor deposition technology is simple, environmentally friendly, non-polluting, less consumable, uniform and compact, and strong in binding to the substrate. Common colors are golden yellow ( TiN), bright silver (CrN), purple (TiAlN) and so on. High quality and multiple choices: The PVD film has a wide variety of colors, and the surface is fine and smooth, rich in metallic luster, and never fades. Convenient cleaning: You can save (reduce) the time and cost of cleaning and polishing general copper (gold) products, and a soft cloth or glass cleaner is sufficient to clean the PVD film.ĥ. Since the process of PVD Coating happens in a vacuum environment, it is more environmentally friendly than other traditional coating techniques such as electroplating and painting.Ĥ. Nearly all types of inorganic and some organic coating materials can be used on many groups of substrates and surfaces using a wide variety of finishes.ģ. ![]() Compared with other coatings, for example, electroplating, PVD coatings are sometimes harder and more resistant to corrosion.Ģ. (3) The plating atoms, molecules or ions are deposited on the substrate. ![]() (2) Migration of plating atoms, molecules or ions: a variety of reactions occurs after the collision of atoms, molecules or ions. (1) Gasification of the plating material: that is, the plating material is evaporated, dissimilar, or sputtered. The basic principles of physical vapor deposition technology can be divided into three process steps: The main methods of physical vapor deposition include vacuum evaporation, sputtering deposition, arc plasma plating, ion plating, etc. PVD film has fast deposition speed as well as strong adhesion, good diffraction, and a wide application range. Then, a film having a specific function is deposited on the surface of the substrate by a low-pressure gas (or plasma). Physical Vapor Deposition (PVD) is a thin film preparation technique that physically vaporizes the surface of a material source (solid or liquid) into gaseous atoms, molecules, or partially ionized into ions under vacuum conditions.
