Silicon carbide (sic) surramicsAn san su da ƙarfin su na ban sha'awa, juriya da zafi, da kuma tsorewa. Waɗannan kaddarorin suna sa su zama da kyau don amfani a cikin mahallai ne injunan Aerospace ko injunan masana'antu. Amma yaya daidai waɗannan kayan aikin da aka kirkira? Bari mu rushe tsarin mataki-mataki.
1.Raw abu shiri
Duk yana farawa da tsarkakakken silicon carbide foda. Yi tunanin wannan a matsayin "gari" don yin burodi "cake." Don haɓaka kayan ƙarshe na ƙarshe - suna gauraye a cikin.
2. Gada yumbu
Daga nan sai aka juya foda ya zama tsari mai ma'ana. Ana amfani da hanyoyin guda biyu:
Pressing: foda yana da foda a cikin takamaiman tsari ta amfani da babban matsin lamba, mai kama da cakuda dusar ƙanƙara cikin dusar ƙanƙara.
Abubuwan da allura: An gauraya foda tare da mai ba da wucin gadi (kamar kakin zuma) don ƙirƙirar cakuda da kullu, wanda ake allurar cikin molds don sifofin hadaddun.
A wannan matakin, har yanzu kayan har yanzu yana da rauni-kamar busassar subule-kuma yana buƙatar "gasa" don zama mai ƙarfi.
3. Tsarin naiyanci
Nan ne sihiri ya faru. Tsabtace yumbu yana mai zafi a cikin farfaden wuta na musamman a matsanancin zafi (sau da yawa sama da 1,800 ° C). A lokacin ake yi wa yin hira, abubuwa guda biyu suna faruwa:
Ruferyan silicon Carbide: hatsi silicon Carbide sun yi kusa, kawar da gibba da samar da ingantaccen tsari.
Aiki mai ƙari: kara abubuwan da aka girka narke kadan, haifar da "gada" tsakanin barbashi don haɓaka tauri.
Yanayin da ke cikin tanderace yana sarrafawa sosai-wani lokacin cike da gas na ƙwayar cuta - don hana halayen da ba a so.
4. Kammala ya taba
Bayan saƙa, yumbu na iya yin ƙarin ƙarin jiyya don daidaita aikinta:
Polishing: Don aikace-aikacen da ke buƙatar santsi saman (misali, seales ko bearings).
Inating: Layer na kariya (kamar silicon nittride) za'a iya ƙara don bunkasa juriya.
Mactining: madaidaicin yankan ko hakowa don samun girma ta ƙarshe.
Me yasa wannan tsari batutuwa
Sirrin Silibiya Carbide ya ta'allaka ne da yadda zarra ta zarra yayin yin mata. Tsarin high-zazzabi yana ƙirƙirar cibiyar sadarwa mai ƙarfi silicon-carbon shaidu, waɗanda suke da tsayayya da zafi, lalata, da damuwa na zahiri. Additive da kuma ingancin yanayin zafin jiki tabbatar da samfurin ƙarshe ba mai wahala ba amma ma suna da wahala don yin tsayayya da fataka.
Hoto mafi girma
Daga yankan-yankewa-gefen Turbines don tsarin sarrafa masu gurbatawa, Silicon Carbide suna taka muhimmiyar rawa a fasaha na zamani. Duk da yake tsarin masana'antu yana da hadaddun, Injiniya ne a hankali na kimiya da injiniya da ke yin sauki foda a cikin kayan da zai iya nuna ƙazamar yanayi.
A matsayin cigaba ci gaba, sabbin hanyoyin-kamar buga 3D na Bramics - suna fitowa ne, alkalin da har ma da karin amfani da wannan kayan masarufi.
