“…Hollow cathodes are used in a wide variety of applications: as efficient light sources [23], as sources of electrons [207][208][209][210][211][212][213] to generate excited species for elemental analysis [1,152,183,214], as ion sources [3,199,[215][216][217][218][219], for nitriding [220][221][222][223], space propulsion [224][225][226], vacuum welding [227], basic plasma research [228,229], cluster formation [230] and plasma-activated pre-treatment and coating processes [231][232][233] among others.…”

In order to understand the plasma cutting process for improving the reliability for stable cutting with a prolonged lifetime, the whole region of oxygen plasma jet, namely, a hafuium electrode as a cathode buried in the water-cooled copper sheath, an arc plasma and a copper nozzle as an anode is treated in a unified numerical model. Calculations are made for the two-dimensional distributions of temperature and fluid flow velocity in the whole region of the oxygen plasma jet for a 400 A in arc current. The current density distribution and also the whole energy balance at the tip of cathode and water-cooled copper sheath are predicted. It is shown that the nozzle diameter strongly affects the plasma jet properties and also the nozzle lifetime but weakly affects the hafuium cathode lifetime.

“…Recently, the welding technology of magnesium alloys, including friction stir welding, tungsten inert gas (TIG) welding, laser hybrid welding or electron-beam welding processes, have been investigated widely [11][12][13][14][15][16][17][18][19][20]. One of these methods is also gastungsten arc (GTA) welding, which has been used extensively for the advantages of utility and economy (i.e.…”
