1,Description:
Tungsten heating vacuum coating, also known as tungsten evaporation coating or tungsten thermal evaporation, is a process used in vacuum deposition to create thin films or coatings of tungsten on various substrates. Here is an English description of tungsten heating vacuum coating:
Tungsten heating vacuum coating is a technique used to deposit thin films or coatings of tungsten onto a substrate surface in a vacuum environment. The process involves the controlled evaporation of tungsten using high temperatures, typically achieved through resistive heating.
In this method, a tungsten filament is heated to its vaporization temperature within a vacuum chamber. As the filament reaches its high temperature, tungsten atoms are released and form a vapor. These tungsten vapor atoms then condense onto the substrate, resulting in the deposition of a thin tungsten film.
