Lanthanated tungsten Alloy Rod
Apejuwe
Lanthanated tungsten jẹ ẹya oxidized lanthanum doped tungsten alloy, tito lẹšẹšẹ bi oxidized toje tungsten aiye (W-REO).Nigbati o ba ti tuka lanthanum oxide ti wa ni afikun, tungsten lanthanated ṣe afihan imudara ooru resistance, iba ina elekitiriki, resistance ti nrakò, ati iwọn otutu recrystallization ti o ga.Awọn ohun-ini to dayato wọnyi ṣe iranlọwọ fun awọn amọna tungsten lanhanated lati ṣaṣeyọri iṣẹ iyasọtọ ni agbara ibẹrẹ arc, resistance ogbara, ati iduroṣinṣin arc ati iṣakoso.
