Shiri tsari na SIC shafi

A halin yanzu, hanyoyin shirye-shiryenSiC shafigalibi sun haɗa da hanyar gel-sol, hanyar sakawa, hanyar shafa buroshi, hanyar fesa plasma, hanyar amsawar tururi (CVR) da hanyar sanya tururi (CVD).

Hanyar sakawa
Wannan hanya wani nau'i ne na babban zafin jiki mai ƙarfi-lokaci sintering, wanda yafi amfani da Si foda da C foda a matsayin saka foda, sanyagraphite matrixa cikin saka foda, da sinters a high zafin jiki a inert gas, kuma a karshe samuSiC shafia saman matrix graphite. Wannan hanya yana da sauƙi a cikin tsari, kuma sutura da matrix suna da alaƙa da kyau, amma haɗin kai tare da jagorancin kauri ba shi da kyau, kuma yana da sauƙi don samar da ƙarin ramuka, yana haifar da rashin ƙarfi na oxidation.

Hanyar shafawa
Hanyar shafan goga galibi tana goge albarkatun ruwa a saman matrix ɗin graphite, sannan ya ƙarfafa albarkatun ƙasa a wani zafin jiki don shirya sutura. Wannan hanya mai sauƙi ne a cikin tsari kuma mai sauƙi a cikin farashi, amma suturar da aka shirya ta hanyar gyaran gyare-gyaren goga yana da rauni mai rauni tare da matrix, rashin daidaituwa mara kyau, suturar bakin ciki da ƙananan juriya na iskar shaka, kuma yana buƙatar wasu hanyoyi don taimakawa.

Hanyar fesa Plasma
Hanyar fesa Plasma galibi tana amfani da bindigar plasma don fesa narkakkar ko narkar da albarkatun ƙasa a saman faifan graphite, sannan kuma yana ƙarfafawa da ɗaure don samar da sutura. Wannan hanyar tana da sauƙi don aiki kuma tana iya shirya ɗan ƙaramin ƙarfisilicon carbide shafi, amma dasilicon carbide shafiwanda aka shirya ta wannan hanyar sau da yawa yana da rauni sosai don samun ƙarfin juriya na iskar shaka, don haka ana amfani da shi gabaɗaya don shirya kayan haɗin gwiwar SiC don haɓaka ingancin sutura.

Hanyar gel-sol
Hanyar gel-sol galibi tana shirya yunifom da bayani na sol don rufe saman saman, ya bushe shi a cikin gel, sa'an nan kuma sanya shi don samun sutura. Wannan hanyar yana da sauƙi don aiki kuma yana da ƙananan farashi, amma murfin da aka shirya yana da rashin amfani kamar ƙananan juriya na zafi da sauƙi mai sauƙi, kuma ba za a iya amfani da shi sosai ba.

Hanyar amsawar tururi (CVR)
CVR galibi yana haifar da tururin SiO ta hanyar amfani da Si da SiO2 foda a babban zafin jiki, kuma jerin halayen sinadarai suna faruwa akan farfajiyar kayan kayan C don samar da suturar SiC. Rufin SiC da aka shirya ta wannan hanyar yana da alaƙa tam zuwa ma'auni, amma yawan zafin jiki yana da girma kuma farashin yana da yawa.
