Vacuum carburizing nugushyushya igihangano muri vacuum.Iyo igeze ku bushyuhe hejuru y’ingingo zikomeye, izahagarara mu gihe runaka, itesha agaciro kandi ikureho firime ya oxyde, hanyuma inyure muri gaze ya carburizing isukuye kugirango ikorwe kandi ikwirakwizwe.Ubushyuhe bwa carburizing ya vacuum carburizing iri hejuru, kugeza 1030 and, kandi umuvuduko wa carburizing urihuta.Igikorwa cyo hejuru cyibice bya karubisi cyatejwe imbere no gutesha agaciro no kwangiza.Umuvuduko ukurikiraho ni mwinshi cyane.Carburizing na diffuzione bikorwa inshuro nyinshi kandi bigasimburana kugeza igihe ubuso bukenewe hamwe nubujyakuzimu bugeze.
Vacuum carburizing ubujyakuzimu hamwe nuburinganire bwubutaka burashobora kugenzurwa;Irashobora guhindura imiterere ya metallurgjique yubuso bwibice byicyuma, kandi ubujyakuzimu bwayo bwimbitse burimbitse kuruta ubujyakuzimu bwa carburizing bwubundi buryo.
