Igikoresho cya SiC ni iki?

Silicon Carbide (SiC)zirimo kuba ingirakamaro muburyo butandukanye bwo gukora cyane bitewe nuburyo budasanzwe bwumubiri nubumara. Byakoreshejwe muburyo bwa tekinike nka fiziki yumubiri cyangwa imiti (CVD), cyangwa uburyo bwo gutera,SiChindura ubuso bwibintu bigize ibice, utange uburyo burambye bwo kwihanganira no kurwanya ibihe bikabije.

Kuki SiC Coatings?
SiC izwi cyane kubera gushonga cyane, gukomera bidasanzwe, no kurwanya ruswa na okiside. Iyi mico irakoraSiCcyane cyane mukurwanya ibidukikije bikabije byahuye ninganda zo mu kirere no kurinda umutekano. By'umwihariko, SiC nziza cyane yo gukuraho ubushyuhe buri hagati yubushyuhe buri hagati ya 1800-2000 ° C ituma ihitamo ryiza kubisabwa bisaba kuramba no kwizerwa mubushyuhe bukabije hamwe nubukanishi.
Uburyo Rusange KuriSiCGusaba:
1.Ibikoresho byoherejwe na chimique (CVD):
CVD ni tekinike yiganje aho ibice bigomba gutwikirwa bishyirwa mumiyoboro ya reaction. Ukoresheje Methyltrichlorosilane (MTS) nkibibanziriza, SiC ishyirwa hejuru yikintu ku bushyuhe buri hagati ya 950-1300 ° C mugihe cy'umuvuduko muke. Iyi nzira iremeza umwe,ubuziranenge bwa SiC, kuzamura ibice byo kwihangana no kubaho.

2.Precursor Impregnation na Pyrolysis (PIP):
Ubu buryo bukubiyemo kubanza kuvura ibice bikurikirwa no kwinjiza vacuum mugisubizo ceramic precursor solution. Nyuma yo gutwita, ibice bikorerwa pyrolysis mu itanura, aho bikonje kugeza ubushyuhe bwicyumba. Igisubizo ni igicucu gikomeye cya SiC gitanga uburinzi budasanzwe bwo kwirinda isuri.

Gusaba hamwe ninyungu:
Imikoreshereze yimyenda ya SiC yongerera ubuzima ibice byingenzi kandi igabanya amafaranga yo kubungabunga itanga urwego rukomeye, rukingira rukingira ibidukikije. Mu kirere, nk'urugero, iyi myenda ni ntangarugero mu kurinda ihungabana ry'ubushyuhe no kwambara. Mu bikoresho bya gisirikare, impuzu za SiC zongerera ubwizerwe n'imikorere y'ibice by'ingenzi, bigatuma ubunyangamugayo bukora ndetse no mu bihe bikomeye.
Umwanzuro:
Mugihe inganda zikomeje gushimangira imipaka yimikorere nigihe kirekire, impuzu za SiC zizagira uruhare runini mugutezimbere ibikoresho siyanse nubuhanga. Hamwe nubushakashatsi burimo gukorwa niterambere, nta gushidikanya ko SiC izaguka, igashyiraho ibipimo bishya muburyo bukomeye.
