Vapor Deposition (VD)

Definition - What does Vapor Deposition (VD) mean?

Vapor deposition (VD) is a coating process in which materials in a vapor state are condensed through the processes of condensation, chemical reaction or conversion to form a solid layer over a substrate. This thin film may be applied for a number of reasons, including protection against corrosion.

Corrosionpedia explains Vapor Deposition (VD)

The vapor deposition process applies a thin coating to the surface of the substrate. This coating process is used to improve the substrate's corrosion resistance, as well as the following properties:

  • Mechanical
  • Electrical
  • Thermal
  • Optical
  • Wear

There are two categories of vapor deposition processes:

  • Chemical vapor deposition (CVD): Chemical gases or vapors react on the surface of the solid, producing a solid byproduct on the surface in the form of a thin film. Other byproducts are volatile and leave the surface.
  • Physical vapor deposition (PVD): Encompasses several deposition technologies in which material is released from a source and transferred to the substrate.
