Explore: Vacuum Arcs

A vacuum arc can arise when the surfaces of metal electrodes in contact with a good vacuum begin to emit electrons either through heating (thermionic emission)

Vacuum arc remelting (VAR) is a secondary melting process for production of metal ingots with elevated chemical and mechanical homogeneity for highly demanding

excessive heat and damage from the arcs. Once the electrodes have reached the heavy melt at the base of the furnace and the arcs are shielded by the scrap, the

projectors. Electric arcs can be utilized for manufacturing processes, such as electric arc welding, plasma cutting and electric arc furnaces for steel

A vacuum (pl.: vacuums or vacua) is space devoid of matter. The word is derived from the Latin adjective vacuus (neuter vacuum) meaning "vacant" or "void"

A vacuum tube, electron tube, thermionic valve (British usage), or tube (North America) is a device that controls electric current flow in a high vacuum

of the electrical contacts results in a metal vapour arc, which is quickly extinguished. Vacuum interrupters are widely used in utility power transmission

speculative methods have also been proposed, like the Mach effect, the quantum vacuum plasma thruster or various hypotheses associated with resonant cavity thrusters

A vacuum arc thruster (VAT) is a form of electric spacecraft propulsion. It uses a vacuum arc discharge, across an insulator, between two electrodes to

implantation and deposition and plasma diagnostics of vacuum arcs. His text book on cathodic arcs and his generalized structure zone diagram are highly
