Izinhlanganisela zekhabhoni / ikhabhoni(okuzobizwa kamuva ngokuthi “C / C noma CFC”) iwuhlobo lwento eyinhlanganisela esekelwe kukhabhoni futhi iqiniswe yi-carbon fibre kanye nemikhiqizo yayo (i-carbon fibre preform). Inakho kokubili inertia ye-carbon namandla aphezulu e-carbon fiber. Inezici ezinhle zokusebenzisa imishini, ukumelana nokushisa, ukumelana nokugqwala, i-friction damping kanye nezici ze-thermal kanye ne-electrical conductivity.
I-CVD-SiCukugqoka kunezici zesakhiwo esifanayo, izinto ezihlangene, ukumelana nokushisa okuphezulu, ukumelana ne-oxidation, ukuhlanzeka okuphezulu, ukumelana ne-asidi & alkali kanye ne-reagent ye-organic, enezakhiwo ezinzile ngokomzimba namakhemikhali.
Uma kuqhathaniswa ne-high-purity graphite materials, i-graphite iqala ukufaka i-oxidize ku-400C, okuzobangela ukulahlekelwa kwempushana ngenxa ye-oxidation, okuholela ekungcoleni kwemvelo kumadivayisi we-peripheral kanye nama-vacuum chamber, futhi kwandise ukungcola kwemvelo ehlanzekile.
Kodwa-ke, ukufakwa kwe-SiC kungagcina ukuzinza ngokomzimba namakhemikhali kumadigri ayi-1600, Kusetshenziswa kabanzi embonini yesimanje, ikakhulukazi embonini ye-semiconductor.
Inkampani yethu ihlinzeka ngezinsizakalo zenqubo yokuhlanganisa ye-SiC ngendlela ye-CVD ebusweni be-graphite, i-ceramics nezinye izinto, ukuze amagesi akhethekile aqukethe i-carbon ne-silicon aphendule ekushiseni okuphezulu ukuze athole ukuhlanzeka okuphezulu kwama-molecule e-SiC, ama-molecule afakwe ebusweni bezinto ezimboziwe, ukwakha isendlalelo sokuzivikela se-SIC. I-SIC eyakhiwe ihlanganiswe ngokuqinile nesisekelo se-graphite, inikeze isisekelo se-graphite izakhiwo ezikhethekile, ngaleyo ndlela yenza ubuso be-graphite compact, i-Porosity-free, ukumelana nokushisa okuphezulu, ukumelana nokugqwala kanye nokumelana ne-oxidation.
Izici eziyinhloko:
1. Ukumelana nokushisa okuphezulu kwe-oxidation:
ukumelana ne-oxidation kusekuhle kakhulu lapho izinga lokushisa liphezulu njenge-1600 C.
2. Ukuhlanzeka okuphezulu: okwenziwe yi-chemical vapor deposition ngaphansi kwesimo sokushisa okuphezulu kwe-chlorination.
3. Ukumelana nokuguguleka: ubulukhuni obuphezulu, indawo ehlangene, izinhlayiya ezinhle.
4. Ukumelana nokugqwala: i-asidi, i-alkali, usawoti kanye nama-organic reagents.
