I-Lanthanate tungsten Alloy Rod
Incazelo
I-Lanthanate tungsten iyingxubevange ye-lanthanum doped tungsten ene-oxidized, ehlukaniswa njenge-oxidized rare earth tungsten (W-REO).Uma i-lanthanum oxide ehlakaziwe yengezwa, i-lanthanated tungsten ibonisa ukumelana nokushisa okuthuthukisiwe, ukuqhutshwa kwe-thermal, ukumelana nokukhasa, kanye nezinga lokushisa eliphezulu lokuvuselela kabusha.Lezi zakhiwo ezivelele zisiza ama-electrode e-tungsten e-lanthanate afinyelele ukusebenza okukhethekile ekhonweni lokuqala le-arc, ukumelana nokuguguleka kwe-arc, nokuzinza kwe-arc nokulawula.
Izakhiwo
Ama-electrode e-tungsten e-earth oxide angavamile, afana ne-W-La2O3 ne-W-CeO2, anezici eziningi zokushisela eziphezulu.Ama-electrode e-tungsten e-doped earth oxide amelela izakhiwo ezinhle kakhulu phakathi kwama-electrode e-Gas Tungsten Arc Welding (GTAW), eyaziwa nangokuthi i-Tungsten Inert Gas (TIG) welding kanye ne-Plasma Arc Welding (PAW).Ama-oxide angezwe ku-tungsten andisa izinga lokushisa lokwenziwa kabusha kwekristalu futhi, ngasikhathi sinye, akhuthaze izinga lokukhishwa kwezinto ngokwehlisa umsebenzi we-electron we-tungsten.

Izici
Imikhiqizo yethu ye-tungsten eyenziwe nge-lanthanate ihlanganisa i-WLa10 (La2O3 1-1.2 wt.%), i-WLa15 (La2O3 1.5-1.7 wt.%), kanye ne-WLa20 (La2O3 2.0-2.3 wt.%). amazinga ezinhlobonhlobo zezinhlelo zokusebenza.Sinikeza ama-electrode e-tungsten e-lanthanated okushisela i-Tungsten Inert Gas (TIG), ukushisela okungazweli, nokufafaza nge-plasma.Siphinde futhi sinikeze izinti ezinkulu ze-WLa ezinobubanzi ukuze zisetshenziswe ezingxenyeni ze-semiconductor nasezithandweni zokushisa eziphezulu.
Izinhlelo zokusebenza
Ama-electrodes we-WLa TIG welding aqalwa kalula futhi ahlala isikhathi eside.Ama-electrodes e-WLa plasma spray abonisa ukumelana okuhle kakhulu nakho kokubili ukuguguleka kwe-arc kanye nezinga lokushisa eliphezulu futhi anokushisa okuphezulu.Ama-electrode welding we-WLa anendawo ephezulu yokuncibilika futhi anikeza ukuzinza okuvelele kokusebenza.
