ABSTRACT: Physical vapor deposition (physical vapor deposition, PVD) is the use of a physical process, such as thermal evaporation of the material or subject to the phenomenon of particle bombardment, the surface atoms of a substance such as sputtering, depositing a coating from a source material to a controllable transfer material atoms process, which is deposited on the scale of the molecules, atoms level. PVD coating technology with low deposition temperature, the substrate can be prepared multilayer nanocomposites structure, environment friendly and so on . In this paper, a brief overview of the PVD coating technology for tools development, operating principles and its application.
