PVD process flow diagram. Physical vapor deposition (PVD), sometimes called physical vapor transport (PVT), describes a variety of vacuum deposition methods which can be used to produce thin films and coatings on substrates including metals, ceramics, glass, and polymers. PVD is characterized by a process in which the material transitions from ...
EPVD technology was developed by Paradigm Shift Technologies, Inc., a Canadian company founded in 1995. It was invented to replace the traditional chrome plating. [1]Thin-film deposition is the overarching technology from which PVD, CVD, ALD, EBPVD, and EPVD are derived, each employing different methods to achieve specific coating characteristics.
Hard chrome, also known as industrial chrome or engineered chrome, is used to reduce friction, improve durability through abrasion tolerance and wear resistance in general, minimize galling or seizing of parts, expand chemical inertness to include a broader set of conditions (such as oxidation resistance), and bulking material for worn parts to ...
Sputter deposition is a physical vapor deposition (PVD) method of thin film deposition by the phenomenon of sputtering. This involves ejecting material from a "target" that is a source onto a "substrate" such as a silicon wafer. Resputtering is re-emission of the deposited material during the deposition process by ion or atom bombardment. [1] [2]
[1] Vacuum deposition is a group of processes used to deposit layers of material atom-by-atom or molecule-by-molecule on a solid surface. These processes operate at pressures well below atmospheric pressure (i.e., vacuum). The deposited layers can range from a thickness of one atom up to millimeters, forming freestanding structures.
The PVD process can be carried out at lower deposition temperatures and without corrosive products, but deposition rates are typically lower. Electron-beam physical vapor deposition, however, yields a high deposition rate from 0.1 to 100 μm/min at relatively low substrate temperatures, with very high material utilization efficiency. The ...

Custom wheels come in many different finishes. The most common custom wheel finishes are Chrome, Polished and Painted. Chrome wheels consist of traditional chrome plating as well as the new process of PVD (Physical Vapor Deposition) Chrome. PVD chrome wheels are protected with a clear coat and are now being introduced by several wheel companies.
