Isima ya Carbide Yacumuye Ibicuruzwa hamwe nisesengura ryimpamvu

Carbide ya sima ni ifu ya metallurgie yifu yinjijwe mumatanura ya vacuum cyangwa itanura rya hydrogène hamwe na cobalt, nikel, na molybdenum nkibice byingenzi bigize tungsten karbide micron nini yifu yicyuma gikomeye.Gucumura ni intambwe ikomeye cyane muri karbide ya sima.Ibyo bita gucumura ni ugushyushya ifu igereranije n'ubushyuhe runaka, ukayigumana mugihe runaka, hanyuma ukayikonjesha kugirango ubone ibikoresho bifite imitungo isabwa.Igikorwa cyo gucumura karbide ya sima iragoye cyane, kandi biroroshye kubyara imyanda yacumuye niba utitonze.Uyu munsi, Chuangrui Xiaobian azabagezaho imyanda isanzwe yacumuye nimpamvu.

1. Carbide yacumuye imyanda niyambere gukuramo
Nukuvuga ko ubuso bwa karbide ya sima inyura mubice kumpande, ibisasu cyangwa ibisasu, kandi mubihe bikomeye, uruhu ruto ruto nk'iminzani y'amafi, ibisasu biturika, ndetse na pulverisation.Gukuramo ahanini biterwa ningaruka zo guhura na cobalt muri compact, kuburyo gaze irimo karubone ibora karubone yubusa muri yo, bigatuma imbaraga zaho zigabanuka, bikavamo gukuramo.

2. Iyakabiri ya sima ikunze kugaragara cyane karbide yacumuye imyanda
Imyenge iri hejuru ya micron 40 yitwa pore.Ibintu bishobora gutera ibisebe bishobora gukora imyenge.Byongeye kandi, iyo hari umwanda mumubiri wacumuye udatwarwa nicyuma gishongeshejwe, nkibinini binini nka "bidakandamijwe", cyangwa umubiri wacumuye bifite icyiciro gikomeye kandi Gutandukanya icyiciro cyamazi bishobora gukora imyenge.

3. Ikintu cya gatatu gikunze kugaragara cyane cbide cbide yacumuye imyanda ni bliste
Hano hari umwobo mubicuruzwa bya sima ya karbide, kandi hejuru ya convex igoramye igaragara hejuru yibice bijyanye.Iyi phenomenon yitwa blisting.Impamvu nyamukuru yo guhuha ni uko umubiri wacumuye wagereranije gaze.Mubusanzwe hariho ubwoko bubiri: bumwe nuko umwuka urundanya mumubiri wacumuye, kandi mugihe cyo kugabanuka kwicyaha, umwuka uva imbere ujya hejuru.Niba hari umwanda wubunini runaka mumubiri wacumuye, nkibisigazwa byamavuta, ibisigazwa byicyuma, hamwe na cobalt, umwuka uzibanda hano.Umubiri umaze gucumura ugaragara mugice cyamazi kandi ukaba mwinshi, umwuka ntushobora gusohoka.Ibibyimba bikora ku buso buto.

Iya kabiri ni uko hari reaction ya chimique itanga gaze nyinshi mumubiri wacumuye.Iyo hari oxyde zimwe mumubiri zacumuye, ziragabanuka nyuma yicyiciro cyamazi gisa nkibyara gaze, izakora ibicuruzwa byinshi;Amavuta ya WC-CO muri rusange agizwe na Byatewe na agglomeration ya oxyde ivanze.

4. Hariho kandi ishyirahamwe ridahwanye: kuvanga

5, hanyuma hakabaho deformasiyo
Guhindura imiterere idasanzwe yumubiri wacumuye byitwa deformation.Impamvu nyamukuru zitera guhindagurika ni izi zikurikira: gukwirakwiza ubucucike bwamasezerano ntabwo arimwe, kuko ubucucike bwuruvange rwuzuye burasa;umubiri wacumuye ubura cyane muri karubone mugace, kuko kubura karubone bigabanya icyiciro cyamazi ugereranije;gupakira ubwato ntabwo bifite ishingiro;isahani yinyuma ntiringana.
