Utwuma twa Tungsten Carbide
Iyo habaye guhitamo neza, ibyuma bya karubide ya tungsten bifite ingano ya submicron bishobora gutyazwa kugeza ku mpande zombi nta bukonje busanzwe bukunze kujyana na karubide isanzwe. Nubwo karubide idakomeye nk'icyuma, irashaje cyane, ifite ubukana bungana na Rc 75-80. Ibyuma bisanzwe bishobora kumara nibura ibyuma 50X mu gihe byirinzwe gucika no kwangirika.
Nkuko bimeze mu guhitamo icyuma, guhitamo urwego rwiza rwa tungsten carbide (WC) ni inzira igoye isaba amahitamo adahwitse hagati yo kudashira no gukomera/guhangana n'ihungabana. Tungsten carbide ikozwe hakoreshejwe gusya (ku bushyuhe bwinshi) ifu ya tungsten carbide hamwe na cobalt ifu (Co), icyuma gifata icyuma gikoreshwa mu gusya (ku bushyuhe bwinshi) gikoreshwa nk' "igifunga" cy'uduce twa tungsten carbide dukomeye cyane. Ubushyuhe bw'uburyo bwo gusya ntibusaba ingaruka z'ibice bibiri, ahubwo butuma cobalt igera hafi y'amazi maze ikaba nk'umubumbe wa kole ufunganye ku duce twa WC (tudahungabanywa n'ubushyuhe). Ibipimo bibiri, ari byo ikigereranyo cya Cobalt na WC n'ingano y'uduce twa WC, bigenzura cyane imiterere y'ibikoresho byinshi by'igice cya "tungsten carbide ifuye".
Kugaragaza ingano nini y'uduce twa WC n'ijanisha rinini rya Cobalt bizatanga igice kidahungabana cyane (kandi gifite imbaraga nyinshi). Uko ingano y'uduce twa WC iba nto (bityo, ubuso bwa WC bugomba gusigwaho Cobalt) niko Cobalt ikoreshwa iba nto, niko igice gikomokaho kirushaho gukomera no kudashira. Kugira ngo karubide ikore neza nk'icyuma, ni ngombwa kwirinda gucika intege vuba bitewe no gucika cyangwa kwangirika, ariko icyarimwe hakemezwa ko nta gucika intege guterwa no gucika intege.
Mu buryo bufatika, gukora impande zicamo cyane kandi zifite inguni zito cyane bisaba ko hakoreshwa carbide nziza mu gukoresha icyuma (kugira ngo hirindwe ko hagira uduce duto n'impande zigoye). Bitewe n'ikoreshwa rya carbide ifite ingano isanzwe ya mikoroni 1 cyangwa munsi yayo, imikorere y'icyuma cya carbide; bityo, ihinduka ahanini na % bya Cobalt n'imiterere y'impande yagenwe. Uburyo bwo gukata burimo imitwaro iri hagati kugeza ku isonga bushobora kwitabwaho neza hagaragazwa 12-15% bya Cobalt n'imiterere y'impande ifite inguni iriho ya 40º. Uburyo bwo gukata burimo imitwaro yoroheje kandi butanga agaciro ku gihe kirekire cy'icyuma ni byiza gukoresha carbide irimo 6-9% bya cobalt kandi ifite inguni iriho iri hagati ya 30-35º.
HUAXIN CARBIDE yiteguye kugufasha kugera ku buringanire bwiza bw'imiterere izagufasha kubona umusaruro mwiza uturutse ku blade za carbide zawe.
HUAXIN CARBIDE itanga ubwoko butandukanye bw'ibyuma byo gukata karubide birimo urwembe
