Abubuwan da aka sake yi na silicon carbide
Silicone carbide Recrystallized (R-SiC) abu ne mai girman gaske tare da taurin na biyu kawai zuwa lu'u-lu'u, wanda aka kafa a babban zafin jiki sama da 2000 ℃. Yana riƙe da kyawawan kaddarorin SiC masu yawa, kamar ƙarfin zafin jiki mai ƙarfi, juriya mai ƙarfi mai ƙarfi, juriya mai kyau na iskar shaka, juriya mai ƙarfi na thermal da sauransu.
● Kyakkyawan kayan aikin injiniya. Silikon carbide da aka sake yin amfani da shi yana da ƙarfin ƙarfi da taurin kai fiye da fiber carbon, juriya mai ƙarfi, yana iya yin aiki mai kyau a cikin matsanancin yanayin zafin jiki, yana iya yin kyakkyawan aiki mai daidaitawa a cikin yanayi daban-daban. Bugu da ƙari, yana da sassauci mai kyau kuma ba ya samun sauƙi ta hanyar mikewa da lankwasawa, wanda ke inganta aikinsa sosai.
● Babban juriya na lalata. Silikon carbide da aka sake yin amfani da shi yana da juriya mai ƙarfi ga kafofin watsa labaru iri-iri, yana iya hana yazawar kafofin watsa labaru iri-iri, yana iya kiyaye kaddarorin injinsa na dogon lokaci, yana da mannewa mai ƙarfi, don ya sami tsawon rayuwar sabis. Bugu da ƙari, yana da kwanciyar hankali mai kyau na thermal, zai iya daidaitawa zuwa wani nau'i na canje-canje na zafin jiki, inganta tasirin aikace-aikacensa.
● Yin zuzzurfan tunani ba ya raguwa. Saboda tsarin sintering ba ya raguwa, babu sauran damuwa da zai haifar da lalacewa ko fashe samfurin, kuma ana iya shirya sassan da ke da sifofi masu rikitarwa da madaidaici.
