Operation process of electron gun evaporation coating

Operation process of electron gun evaporation coating

The density of the electron beam emitted by a high-pressure electron gun is very high. If the electron beam landing point is not properly controlled, the electron beam cannot be deflected onto the metal ingot, which may heat the coating chamber wall and other areas. Therefore,
