What is PVD? PVD is an abbreviation of Physical Vapor Deposition, which translates to physical vapor deposition, which means to use physical processes to achieve the transfer of matter and the transfer of atoms or molecules from the source to the surface of the substrate. Its role is to enable certain particles with special properties (high strength, wear resistance, heat dissipation, corrosion resistance, etc.) to be sprayed on the lower performance matrix so that the matrix has better performance. After some of the easily accessible materials are processed by PVD, they have the properties that are difficult to be achieved by the material modification, thereby satisfying people's needs for aesthetics, texture, and weather resistance to some extent.
