TheDahaarka CVD SiCUsha Isku-dhafka ah ee CC,Usha Isku-dhafka ah ee Silikoon Carbide-Kaarboon, Usha isku-dhafka ah ee SiC ee dahaaran CC oo ka timid vet-china waxay isku daraysaa sifooyinka gaarka ah eeisku-darka kaarboon-kaarboon (CC)oo leh ilaalinDahaarka CVD SiC (Silicon Carbide)Ushani horumarsan waxaa loogu talagalay codsiyada waxqabadka sare leh ee u baahan xasillooni kuleyl oo heer sare ah, xoog farsamo, iyo iska caabin kiimiko. Xudunta kaarboon-kaarboon waxay bixisaa cimri dherer aad u fiican iyo sifooyin fudud, halka dahaarka SiC uu xoojiyo iska caabbinta xirashada, oksaydhka, iyo heerkulka sare.
Dahaarka CVD SiC wuxuu bixiyaa ilaalin adag, taasoo u oggolaanaysa usha inay u adkaysato xaaladaha ba'an, taasoo ka dhigaysa mid ku habboon wax soo saarka semiconductor-ka, hawada sare, iyo hababka warshadaha. vet-china waxay hubisaa inDahaarka CVD SiCCC Composite Rod waxay la tacaali kartaa heerkulka ka sarreeya 1600°C, taasoo siinaysa isku hallayn jawi u baahan saxnaan iyo cimri dheer labadaba.
Usha isku-dhafka ah ee xoolaha iyo shiinaha waxaa loo farsameeyay inay ku shaqeyso xaaladaha ugu adag, iyadoo hubinaysa xasilloonida iyo kordhinta cimriga qaybaha warshadaha baahida sare leh. Isku-darka dahaarka CVD SiC iyo qaab-dhismeedka isku-dhafka ah ee CC wuxuu keenaa badeecad aan kaliya ahayn mid fudud laakiin sidoo kale aad u xoog badan oo u adkaysata xirashada iyo jeexitaanka.
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.
