PVD (physical vapor deposition) or physical vapor deposition is widely used on the current international advanced surface treatment technology.

Coating by physical vapour deposition (PVD), coating by chemical vapour deposition (CVD) and surface layer modification by ion implantation, all three are being tested and are partly in use.

The IR spectrum and SEM analysis demonstrated that the graft monomers were bound to the fibers by the ways of physical deposition and chemical bonding.
