Applications of EB Tungsten Filament

The full name of EB tungsten filament is electron beam tungsten filament.

The properties of EB tungsten filament (electron beam tungsten filament) include its small size, non-sagging, good breaking resistance. On the one hand, it has a nice corrosion resistance. On the other hand, the EB tungsten filament has a long life for plating as well as the high thermal conductivity.

Applications of EB tungsten filament:

1. EB tungsten filament can be applied in vacuum coating with e-gun.

A vacuum coating is a kind of technology, which can produce the thin film material by physical method. The electron beam heating has a higher flux density than that of the electric heating. What’s more, the electron beam can evaporate the high melting point materials. The kinetic energy of evaporating particles of the electron beam tungsten filament is large, and it benefits to obtain the membranous layer with a good bonding densification.

2. EB Tungsten filament can be used for emitting tubes filament cathode.

Actually, EB tungsten filament has extensive application in many fields. But people should know the correct way to use it, or its properties would be decreased.
