- FAA'IIDOOYINKA FACEYLKA EE SILICON CARBIDE EE LA XIDHAY
Badeecadaha Reaction Bonded Silicon Carbide (RBSC, ama SiSiC) waxay bixiyaan iska caabin adag/abrasion aad u daran iyo xasillooni kiimiko oo heer sare ah jawiyada dagaalka. Silicon Carbide waa walxo macmal ah oo muujiya astaamo waxqabad sare leh oo ay ku jiraan:
lIska caabin kiimiko oo aad u fiican.
Xoogga RBSC wuxuu ku dhawaad 50% ka weyn yahay inta badan kaarboohaydraytyada silicon ee ku xiran nitride. RBSC waa iska caabbinta daxalka ee ugu fiican iyo dhoobada ka hortagga oksaydhka. Waxaa loo samayn karaa noocyo kala duwan oo ah nalka nadiifinta (FGD).
lXirashada aadka u fiican iyo iska caabinta saameynta.
Waa tignoolajiyada dhoobada ee u adkaysata xoqidda baaxadda weyn. RBSiC waxay leedahay adkeysi sare oo u dhow kan dheemanka. Waxaa loogu talagalay in loo isticmaalo codsiyada qaababka waaweyn halkaas oo heerarka iska caabbinta ee silicon carbide ay muujinayaan xoqid ama dhaawac ka dhasha saameynta walxaha waaweyn. Waxay u adkaysataa xoqidda tooska ah ee walxaha iftiinka iyo sidoo kale saameynta iyo xoqidda simbiriirixan ee walxaha culus ee ka kooban slurries. Waxaa loo samayn karaa qaabab kala duwan, oo ay ku jiraan qaababka koonaha iyo gacmaha, iyo sidoo kale qaybo ka sii adag oo la farsameeyay oo loogu talagalay qalabka ku lug leh farsamaynta walxaha ceeriin.
lIska caabinta shoogga kulaylka oo aad u fiican.
Qaybaha carbide-ka silicon ee ku xiran falcelinta waxay bixiyaan iska caabin shoog kuleyl oo heer sare ah laakiin si ka duwan dhoobada dhaqameed, waxay sidoo kale isku daraan cufnaanta hoose iyo xoogga farsamada sare.
lXoog sare (wuxuu xoog yeeshaa heerkulka).
Kaarboohaydraytka Silicon ee ku xiran falcelinta wuxuu hayaa inta badan awooddiisa farsamo heerkulka sare wuxuuna muujiyaa heerar aad u hooseeya oo gurguur ah, taasoo ka dhigaysa doorashada koowaad ee codsiyada culeyska qaada ee u dhexeeya 1300ºC ilaa 1650ºC (2400ºC ilaa 3000ºF).
