Lanthanated tungsten Alloy Rod
Fa'amatalaga
Lanthanated tungsten o se oxidized lanthanum doped tungsten alloy, faavasegaina o oxidized tungsten eleele seasea (W-REO).Pe a faʻaopoopoina le lanthanum oxide faʻasalalau, faʻaalia e le tungsten lanthanated le faʻaleleia o le vevela, faʻafefe vevela, faʻafefete, ma le maualuga o le vevela.O nei mea mata'ina e fesoasoani i le lanthanated tungsten electrodes e ausia ai le tulaga fa'apitoa i le arc amata gafatia, arc erosion resistance, ma le arc mautu ma le pulea.
Meatotino
E seasea eleele oxide doped tungsten electrodes, e pei o le W-La2O3 ma le W-CeO2, e tele uiga uelo maualuga.E seasea eleele oxide doped tungsten electrodes e fai ma sui o meatotino sili i electrodes mo Gas Tungsten Arc Uila (GTAW), lea e lauiloa foi o le Tungsten Inert Gas (TIG) uelo ma Plasma Arc Uila (PAW).O oxides faʻaopoopo i le tungsten faʻateleina le vevela o le recrystallization ma, i le taimi lava e tasi, faʻalauteleina le maualuga o le faʻamalama e ala i le faʻaitiitia o le galuega eletise a le tungsten.
