hermal vacuum evaporation (resistance evaporation) is a coating method used as part of the PVD process (Physical Vapor Deposition). The material that is to form the subsequent layer is heated in a vacuum chamber until it evaporates.
The vapor formed by the material condenses on the substrate and forms the required layer. Because many coating materials react with water, nitrogen and oxygen, this process is performed in a high vacuum. The high temperatures that are required are generally produced using resistance heaters or, in some cases, induction heaters, electron beams or arcs. Evaporation boats are manufactured from refractory metals such as molybdenum, tungsten or tantalum to help them withstand these high temperatures as well as the chemical aggressions caused by the coating material. |
