Iimbumba zekhabhoni / ikhabhoni(emva koku kuthiwa "C / C okanye CFC") luhlobo lwezinto ezidibeneyo ezisekelwe kwikhabhoni kwaye zomelezwe yi-carbon fiber kunye neemveliso zayo (i-carbon fiber preform). Inayo zombini inertia yekhabhoni kunye namandla aphezulu e-carbon fiber. Ineempawu ezilungileyo zoomatshini, ukumelana nobushushu, ukuxhathisa ukugqwala, ukudambisa i-friction kunye ne-thermal kunye neempawu zombane.
CVD-SiCI-coating ineempawu zesakhiwo esifanayo, i-compact material, ukumelana nobushushu obuphezulu, ukumelana ne-oxidation, ukucoceka okuphezulu, ukuxhathisa kwe-asidi kunye ne-alkali kunye ne-reagent ye-organic, eneempawu ezizinzileyo zomzimba kunye neekhemikhali.
Iimpawu eziphambili:
1. Ukumelana nobushushu obuphezulu be-oxidation:Ukumelana ne-oxidation kusekuhle kakhulu xa ubushushu buphezulu ukuya kuma-1600 C.
2. Ukucoceka okuphezulu: okwenziwe nge-chemical vapour deposition phantsi kwemeko yokushisa kwe-chlorination ephezulu.
3. Ukumelana nokhukuliseko: ubunzima obuphezulu, indawo edibeneyo, iincinci ezincinci.
4. Ukumelana nokubola: i-asidi, i-alkali, ityuwa kunye ne-organic reagents.

I-VET Amandla ngumvelisi wokwenyani weemveliso zegraphite kunye ne-silicon carbide ezineengubo ezahlukeneyo ezifana nokwaleka kwe-SiC, i-TaC yokwambathisa, i-glassy carbon coating, i-pyrolytic carbon coating, njl., inokubonelela ngeendawo ezahlukeneyo ezilungiselelwe i-semiconductor kunye ne-photovoltaic industry.
Iqela lethu lobuchwephesha livela kumaziko aphezulu ophando lwasekhaya, linokubonelela ngezisombululo zemathiriyeli yobuchwephesha.
Sisoloko siphuhlisa iinkqubo eziphambili zokubonelela ngemathiriyeli ephucukileyo, kwaye sisebenze itekhnoloji eyodwa enelungelo elilodwa lomenzi wechiza, enokwenza iqhina phakathi kwengubo kunye ne-substrate ibe ngqongqo kwaye ingabikho lula ekuthinteleni.
Wamkelekile ngokufudumeleyo ukuba undwendwele umzi-mveliso wethu, makhe sibenengxoxo eyongezelelekileyo!
