Ihe mkpuchi tungsten Alloy Rod
Nkọwa
Tungsten Lanthanated bụ oxidized lanthanum doped tungsten alloy, ahazi ya dị ka oxidized obere ụwa tungsten (W-REO).Mgbe agbakwunyere lanthanum oxide gbasasịrị, tungsten lanthanated na-egosiputa nkwụsi ike okpomoku, conductivity thermal, nguzogide na-akpụ akpụ, yana okpomoku recrystallization dị elu.Ngwongwo ndị a pụtara ìhè na-enyere electrodes tungsten lanthanated aka ịrụ ọrụ pụrụ iche na ike ịmalite arc, nguzogide arc, na nkwụsi ike na njikwa arc.
Njirimara
Igwe ikuku oxide na-adịghị ahụkebe doped tungsten, dị ka W-La2O3 na W-CeO2, nwere ọtụtụ njirimara ịgbado ọkụ.Obere ikuku oxide doped tungsten electrodes na-anọchite anya ihe kacha mma n'etiti electrodes maka Gas Tungsten Arc Welding (GTAW), nke a makwaara dị ka Tungsten Inert Gas (TIG) ịgbado ọkụ na Plasma Arc Welding (PAW).Ihe oxides agbakwunyere na tungsten na-abawanye okpomọkụ recrystallization na, n'otu oge ahụ, kwalite ọkwa ikuku site na ibelata ọrụ ọrụ electron nke tungsten.
