Electron-beam physical vapor deposition, or EBPVD, is a form of physical vapor deposition in which a target anode is bombarded with an electron beam given off by a charged tungsten filament under high vacuum. The electron beam causes atoms from the target to transform into the gaseous phase.

In electron beam evaporation, the source material can be evaporated using high energy electrons in the form of an intense beam. A hot filament causes the thermionic emission of electrons, which can, after acceleration, provide sufficient energy for evaporating any material.

Evaporation is based on the concept that there exists a finite “vapor pressure” above any material. The material either sublimes (direct solid to vapor transition) or evaporates (liquid to vapor transition). Two main types of evaporators: E-beam and filament.

Mar 27, 2023 · E-beam evaporation, also known as electron beam evaporation, is a physical vapor deposition (PVD) process that applies a dense, thin coating to a substrate. The process takes place under high vacuum and relies on a high-power electron beam to evaporate the coating material (the source material).

Jun 15, 2016 · E-Beam or Electron Beam Evaporation is a form of Physical Vapor Deposition in which the target material to be used as a coating is bombarded with an electron beam from a charged tungsten filament to evaporate and convert it to a gaseous state for deposition on the material to be coated.

Mar 29, 2024 · Electron beam evaporation is a form of physical vapour deposition that uses a focused electron beam within a vacuum environment to heat evaporation material. The e-beam evaporation process is based on the emission of electrons from a tungsten filament when exposed to a current.

Electron beam (e-beam) evaporation is a time-tested deposition technology for producing dense, high purity coatings. During an e-beam evaporation process, current is first passed through a tungsten filament, leading to joule heating and electron emission.

Electron beam evaporation, or E-beam evaporation, is a type of physical vapor deposition (PVD) technique, which directly heats the evaporation material (usually pellets) by using an electron beam under vacuum, and transports the vaporized material to the substrate to form a film.
