Gucukumbura ibiranga silicon karbide ceramics

Imiterere yihariye ya porous silicon carbide ceramicsbiterwa ahanini nuburyo bwihariye bwimiterere, burimo ububobere, ubunini bwa pore nogukwirakwiza, nuburyo bwimyobo. Niyo mpamvu, birakenewe kugenzura ububobere bwayo, ubunini bwa pore nogukwirakwiza, hamwe nuburyo bwa pore binyuze muburyo bwo kwitegura kugirango ubone imiterere yifuzwa. Uburyo bwo kuyitegura rero niyo yibanze kubushakashatsi.

Ibyiza bya ceramics ya SiC

1.Ibintu byiza

①Ubwoba

Ububabare ni ijanisha ryijwi ryakozwe na pore mubikoresho byuzuye kugeza mubunini bwibintu byose (harimo imyenge ifunguye, igice cyafunguye igice na pore zifunze zubwoko 3). Ubushakashatsi bwerekana ko imikorere yibikoresho biterwa ahanini nubushake.

Ore Imyitwarire myiza

Imyitwarire ya pore isobanura morphologie ya pore muri ceramics. Iyo imyenge ihwanye na pore, imikorere rusange yibikoresho ni isotropic; ariko iyo imyenge irambuye cyangwa iringaniye, nko kunyura muri karuboni yimbaho ​​zateguwe na silicon reaction ikora sinema ya SiC ceramics, imiterere ya pore nicyerekezo runaka.

③Diameter ya pore no gukwirakwiza

Diameter ya pore iri munsi ya 2nm kubikoresho bya microporome, ubunini bwa pore hagati ya 2 ~ 50nm kubikoresho bya mesoporous, ubunini burenga 20nm kubikoresho bya macroporome. Nubunini bwa pore nogukwirakwiza ingaruka nini zimikorere, harimo kwinjirira, igipimo cyogukora no kuyungurura.

2.Ibikoresho bya mashini

Ceramicibikoresho biravunika kandi imiterere yubukanishi irangwa no kunama cyangwa kwikuramo imbaraga. Uburyo bukomeye nuburyo bwo gutegura bugira ingaruka nini kumiterere yubukorikori bwa ceramics ya SiC.

3.Amashanyarazi

Porosity na pore morphologie bigira ingaruka nini kumashanyarazi yubushyuhe bwa ceramics. Kuri ceramics yamashanyarazi hamwe no gukwirakwiza pore imwe, ubushyuhe bwumuriro buragabanuka buhoro buhoro uko igipimo cya pore cyiyongera. Nyamara, bitewe na pore morphologie yibikoresho bya ceramic byateguwe nuburyo butandukanye, hariho itandukaniro rinini, bityo uburyo bwo kohereza ubushyuhe burahinduka kandi buragoye.

CeramicsKugira imiterere myiza yumubiri ya SiC ubwayo, nkubucucike bwinshi, ubuso bwihariye hejuru yubuso, ubukana bwinshi, kurwanya ruswa, kurwanya ubushyuhe bwinshi, ubushyuhe bwinshi, ubushyuhe buke bwo kwaguka kwinshi, hamwe no guhangana nubushyuhe bwumuriro, hejuru ya kunyurwa na kamere mbi yubutaka.
