Lantanated tungsten Alloy Rod
Sharaxaada
Tungsten Lantanated waa lanthanum oksijiin doped tungsten alloy, oo loo kala saaray sidii tungsten naadirka dhulka oksaydhaysan (W-REO).Marka lanthanum oksaydhka la firdhiyo lagu daro, tungsten lanthanated wuxuu soo bandhigayaa iska caabbinta kulaylka oo la xoojiyey, kulaylka kulaylka, caabbinta gurguurta, iyo heerkul sare oo recrystalization ah.Guryahaan aadka u wanaagsan waxay ka caawiyaan korantada tungsten ee lanthanated inay gaaraan waxqabad aan caadi ahayn xagga awoodda bilawga arc, caabbinta nabaadguurka, iyo xasilloonida iyo xakamaynta arc.
Guryaha
Qalabyada tungsten ee naadirka ah, sida W-La2O3 iyo W-CeO2, waxay leeyihiin sifooyin alxanka oo badan.Qalabyada tungsten-ka ah ee naadirka ah ee dhulka hoostiisa ku jira waxay ka dhigan yihiin kuwa ugu wanaagsan ee elektiroonigga ah ee Gas Tungsten Arc Welding (GTAW), kaas oo sidoo kale loo yaqaan Tungsten Inert Gas (TIG) alxanka iyo Plasma Arc Welding (PAW).Oxideyaasha lagu daray tungsten waxay kordhiyeen heerkulka recrystallization, isla markaana, waxay kor u qaadeen heerka qiiqa iyadoo hoos loo dhigayo shaqada elektaroonigga ah ee tungsten

Astaamaha
Badeecadaha tungsten-ka ee lantanated waxaa ka mid ah WLa10 (La2O3 1-1.2 wt.%), WLa15 (La2O3 1.5-1.7 wt.%), iyo WLa20 (La2O3 2.0-2.3 wt.%). heerarka kala duwan ee codsiyada.Waxaan bixinaa korantada tungsten lanthanated ee tungsten Inert Gas (TIG) alxanka, alxanka adkaysi u leh, iyo buufinta balaasmaha.Waxaan sidoo kale bixinaa ulaha WLa dhexroor weyn si loogu isticmaalo qaybaha semiconductor iyo foornooyinka kulaylka sareeyo.
Codsiyada
Walxaha alxanka WLa TIG si fudud ayaa loo bilaabay oo aad bay u adkeysanayaan.Qalabka buufinta balaasmaha ee WLa waxay muujinayaan iska caabin aad u wanaagsan labada nabaad guurka iyo heerkulka sare waxayna leeyihiin kuleyl heersare ah.Walxaha alxanka iska caabinta WLa waxay leeyihiin bar dhalaalid sare waxayna bixiyaan xasillooni hawleed oo heersare ah.
