Nkigice cyingenzi cyibikoresho byubwubatsi nibikoresho bikora, ibikoresho bya ceramic bigezweho bifite amahirwe menshi yo gukoresha ingufu nshya, itumanaho rya elegitoroniki, semiconductor, icyogajuru nizindi nganda. Nyamara, kubera ko ifu ya ceramic ahanini ari ionic bond cyangwa covalent bond compound, inzira gakondo yo gucumura kugirango itegure ubucucikeibikoresho bya ceramicbisaba ubushyuhe bwo hejuru cyane kandi bifata umwanya muremure, byanze bikunze biganisha ku guhunika ingano hamwe n ibisigara bya porosity, hanyuma bikagira ingaruka kumiterere yagushushanya inshinge. Kugabanyagucumura ibyumaubushyuhe, gabanya igihe cyo gucumura, kunoza ubwinshi bwicyaha nibintu bifatika, abashakashatsi bakoze tekinoroji zitandukanye zo gucumura.
Gutera plasma gucumura (SPS)
Ikoranabuhanga rya SPS ni ubwoko bushya bwikoranabuhanga ryihuta ryibanze cyane kandi ryizwe mwisi yubumenyi. FIG. 1 yerekana ihame ryakazi.
Ikoranabuhanga rya SPS ryatangije uburyo bwo kwinjiza dc pulse muriinzira yo gucumura. Indenter ikora nk'itwara kugirango umuyaga unyure mugihe ushyira igitutu kubintu. Bitandukanye nubuhanga gakondo bwo gucumura, busanzwe bukoresha ubushyuhe bukabije bwumubiri ushyuha, SPS ikoresha ingaruka zumuriro wumuriro munini wamashanyarazi unyura mubibumbano cyangwa ukora icyitegererezo kugirango ushushe ibikoresho. Kubyitegererezo byintangarugero, grafite hamwe nubushobozi bwiza bwamashanyarazi ikoreshwa nkibikoresho, kandi ubushyuhe bwo guhangana nububiko bukoreshwa kugirango icyitegererezo kizamuke vuba. Kuburugero rwicyitegererezo, ifumbire irashobora gukoreshwa kugirango ushushe umuyaga binyuze murugero. Igipimo cyo gushyushya gishobora kugera ku 1000 ℃ / min. Iyo ubushyuhe bwikigereranyo bugeze ku giciro cyagenwe, gucumura birashobora kurangira nyuma yigihe gito cyo kubika ubushyuhe.
Ikoranabuhanga rya SPS rifite ibyiza byubushyuhe buke, igihe gito cyo gufata, ubushyuhe bwihuse, umuvuduko woguhindura, hamwe no guhuza imirima myinshi (amashanyarazi-mashini-yumuriro).
Amashanyarazi (FS)
Ikoranabuhanga rya FS ryatangajwe bwa mbere mu mwaka wa 2010 na Cologna n'abandi bo muri kaminuza ya Colorado, hashingiwe ku bushakashatsi bwakozwe n'ikoranabuhanga rifasha ifu y'icyuma ifasha mu murima (FAST)
Ikoranabuhanga rya FS ririmo cyane cyane ibintu bitatu byerekana inzira, aribyo ubushyuhe bwitanura (Tf), ubukana bwumurima (E) nubu (J). Igishushanyo 3C cyerekana itandukaniro rya buri kintu muburyo bwa FS gakondo. Muri ubu buryo, umurima w'amashanyarazi uhoraho ushyirwa mubikoresho kandi ubushyuhe bw'itanura buzamuka ku gipimo gihoraho. Iyo ubushyuhe bw'itanura buri hasi, ibintu birwanya ibintu biri hejuru kandi umuyaga unyura mubikoresho ni muto. Hamwe n'ubwiyongere bw'ubushyuhe bw'itanura, icyitegererezo cyo kurwanya kiragabanuka kandi ikiyongera buhoro buhoro. Iki cyiciro cyitwa incubation stage kandi sisitemu ni voltage igenzurwa. Iyo ubushyuhe bw'itanura buzamutse ku bushyuhe bukomeye, ibintu birwanya ibintu bigabanuka gitunguranye, umuyaga urazamuka cyane, kandi FS ibaho. Kubera ko imbaraga zumurima zikiri zihagaze muri iki gihe, imbaraga za sisitemu (W = EJ) zizahita zigera ku mbaraga z’amashanyarazi, kandi sisitemu izahinduka kuva kugenzura ingufu zijye kugenzura kugeza ubu, aribyo bita icyiciro cya FS. Iyo kurwanya ibintu bitazamutse, imbaraga zumurima zongeye guhagarara, kandi gucumura byinjira murwego ruhamye, ni ukuvuga icyiciro cya insulation ya FS. Nyuma yicyiciro cyo gukumira, inzira ya FS irangiye.
Ugereranije no gucumura gakondo, FS ifite ibyiza bikurikira: kugabanya igihe cyo gucumura no kugabanya ubushyuhe bwitanura bukenewe mugucumura, kubuza imikurire yintete, birashobora kugera kumucyo utaringaniye, ibikoresho byoroshye, igiciro gito.
