TheDahaarka CVD SiCQaab-dhismeedka CC Composite, Qaab-dhismeedka Kaarboon-Kaarboon, Qaab-dhismeedka C/C ee laga sameeyay Shiinaha xoolaha waa qaab-dhismeed waxqabad sare leh oo loogu talagalay warshadaha u baahan iska caabin kuleyl iyo kiimiko oo heer sare ah.isku-dhafka kaarboon-kaarboonQaab-dhismeedka, oo lagu xoojiyay dahaarka CVD SiC (Silicon Carbide), wuxuu bixiyaa cimri dherer iyo xasillooni heer sare ah heerkulka aadka u daran, taasoo ka dhigaysa mid ku habboon codsiyada adag sida wax soo saarka semiconductor-ka, hawada sare, iyo qaybaha baabuurta.
TheDahaarka CVD SiCWaxay bixisaa iska caabin cajiib ah oo ku aaddan xirashada iyo oksaydhka, iyadoo dheereyneysa cimriga caaryada iyo hubinta waxqabad la isku halleyn karo oo ku jira jawi adag. Tiknoolajiyaddan dahaadhka ee horumarsan waxay sidoo kale hagaajisaa adkaanta dusha sare, iyadoo ilaalinaysa caaryada inta lagu jiro hababka heerkulka sare iyo ka hortagga isbeddelka ama dhaawaca. Caaryada vet-china aad bay ugu habboon yihiin warshadaha isticmaalaGiraangiraha CVD SiCiyo qaybaha, iyagoo bixinaya xal ugu habboon oo loogu talagalay soo saarista saxnaanta sare.
Marka laga soo tago dahaarka SiC,Dahaarka CVD TaCwaxaa sidoo kale loo isticmaali karaa si loo xoojiyo iska caabbinta kiimikada, taasoo ka dhigaysa caaryada mid u habboon codsiyada kala duwan ee u baahan ilaalinta walxaha sunta ah. Khibradda Vet-china ee isku-dhafka CVD SiC iyo C/C waxay hubineysaa in caaryada kasta si sax ah loo sameeyay, taasoo keenaysa waxqabad heer sare ah labada jawi ee warshadaha iyo farsamada.
Isku-darka walxaha isku-dhafan ee CVD SiC iyo kaarboon-kaarboon waxay hubinayaan in CVD SiC Coating CC Composite Mold, Kaarboon-Kaarboon Composite Mold, C/C Mold ay ku fiican tahay hababka ku lug leh kulayl sare, soo-gaadhista kiimikada, iyo walbahaarka farsamada, taasoo siinaysa dadka isticmaala xal caaryada oo waara oo la isku halleyn karo.
Astaamaha ugu muhiimsan:
1. Iska caabinta oksaydhka heerkulka sare:
Iska caabbinta oksaydhku wali aad bay u fiican tahay marka heerkulku uu gaaro 1600 C.
2. Nadiifnimo sare: waxaa lagu sameeyaa kaydka uumiga kiimikada iyadoo xaalad koloriin heerkul sare leh.
3. Iska caabbinta nabaad-guurka: adkaansho sare, dusha sare oo is haysta, walxo yaryar.
4. Iska caabbinta daxalka: aashitada, alkali, milixda iyo walxaha dabiiciga ah.
