Rullaluistemka Silikoon Carbide
Rullaluistemyada Silicon Carbide (SiC)waa qaybaha gudbinta asaasiga ah ee foornada duuban, oo si weyn loogu isticmaalo dab-damiska dhismaha, alaabta nadaafadda, dhoobada guriga, iyo dhoobada elektaroonigga ah. Iyada oo lagu saleynayo habka wax soo saarka, waxaa inta badan loo kala saaraa laba nooc: Reaction Bonded Silicon Carbide (RBSiC) iyo Recrystallized Silicon Carbide (RSiC).
Isbarbardhigga Nooca:
1. SiC-ga ku xiran falgalka (RBSiC):
Halabuurka: Waxaa ku jira xaddi yar oo silikoon bilaash ah.
Faa'iidooyinka: Cufnaan sare, xoog sare, iyo kharash-ool ah.
Heerkulka ugu Sareeya: Ilaa 1400°C.
Adeegsiga: Ku habboon foornada dabka ee heerkulka dhexdhexaadka ah ilaa sare iyo dhoobada guriga. Waxay bixisaa dheelitirka ugu fiican ee waxqabadka iyo qiimaha.
2. SiC dib loo warshadeeyay (RSiC):
Halabuurka: Nadiifnimo sare oo aan lahayn marxalad isku xidhnaan ah.
Faa'iidooyinka: Iska caabin heer-kul sare oo heer sare ah iyo iska caabin gurguurta (isbeddel la'aan marka kulaylka sare jiro).
Heerkulka ugu Sareeya: Ilaa 1650°C+.
Codsiga: Ku habboon in lagu shido heerkul sare oo ah qalabka nadaafadda iyo dhoobada gaarka ah halkaas oo loo baahan yahay xasillooni kuleyl xad dhaaf ah.
Astaamaha Muhiimka ah:
1. Xoog Heerkul Sare oo Sare:Waxay ilaalisaa sifooyinka farsamada ee aadka u fiican xitaa heerkulka u dhexeeya 1400°C ilaa 1600°C.
2. Iska caabinta Shoogga Kulaylka oo Aad u Fiican:Waxay u adkaysataa isbeddellada heerkulka degdegga ah, waxayna ka hortagtaa dildilaaca ama jabka inta lagu jiro wareegyada kululaynta iyo qaboojinta degdegga ah.
3. Iska caabinta Xidhitaanka Sare:Waxay kordhisaa cimriga adeegga waxayna yareysaa kharashyada dayactirka ee deegaannada foornada xoqan.
4. Iska caabbinta Daxalka iyo Oksaydhka:Si fiican ayuu ugu shaqeeyaa jawiyo kala duwan oo foornada ah, isagoo iska caabinaya nabaad-guurka kiimikada.
5. Saxnaanta Cabbirka Sare:Dhammaystirka dusha sare ee siman wuxuu hubiyaa gaadiid deggan oo sax ah oo alaabta dhoobada ah.
