Lanthanate tungsten Alloy Rod
Tlhaloso
Lanthanate tungsten ke motsoako oa oxidized lanthanum doped tungsten alloy, o arotsoe ka oxidized rare earth tungsten (W-REO).Ha lanthanum oxide e qhalakantsoeng e eketsoa, lanthanated tungsten e bonts'a ho hanyetsa mocheso o matlafalitsoeng, conductivity ea mocheso, khanyetso ea creep, le mocheso o phahameng oa recrystallization.Lintho tsena tse ikhethang li thusa li-electrode tsa tungsten tse lanthanated ho fihlela ts'ebetso e ikhethang ho bokhoni ba ho qala ba arc, ho hanyetsa khoholeho ea arc, le botsitso le taolo ea arc.
Thepa
Li-electrode tsa tungsten tsa lefats'e tse sa tloaelehang, tse kang W-La2O3 le W-CeO2, li na le litšobotsi tse ngata tse phahameng tsa ho cheseletsa.Rare earth oxide doped tungsten electrode emela thepa e molemo ka ho fetisisa har'a li-electrode bakeng sa Gas Tungsten Arc Welding (GTAW), eo hape e tsejoang e le Tungsten Inert Gas (TIG) welding le Plasma Arc Welding (PAW).Li-oxide tse kenyellelitsoeng ho tungsten li ile tsa eketsa mocheso oa recrystallization, 'me ka nako e ts'oanang, tsa phahamisa boemo ba tlhahiso ka ho theola tšebetso ea elektronike ea tungsten.
