Ƙirƙirar Hanyoyin Silicon Carbide Ceramics: Cikakken Bayani
Tsarin kristal na musamman da kaddarorin kayan yumbu na silicon carbide suna ba da gudummawa ga kyawawan kaddarorin sa. Suna da kyakkyawan ƙarfi, matsananciyar ƙarfi mai ƙarfi, kyakkyawan juriya na lalacewa, juriya na lalata, haɓakar yanayin zafi mai kyau da juriya mai kyau na thermal. Waɗannan kaddarorin sun sanya yumbu na siliki carbide ya dace don aikace-aikacen ballistic.
Samar da yumbu na siliki carbide yawanci yana ɗaukar hanyoyi masu zuwa:
1. Matsi gyare-gyare: Matsi gyare-gyare ne da yadu amfani hanya domin kerarre silicon carbide harsashi zanen gado. Tsarin yana da sauƙi, mai sauƙi don aiki, babban inganci kuma ya dace da ci gaba da samarwa.
2. Gyaran allura: Gyaran allura yana da kyakkyawar daidaitawa kuma yana iya ƙirƙirar sifofi da sifofi masu rikitarwa. Wannan hanya tana da fa'ida musamman lokacin samar da sassan yumbu na siliki carbide na musamman.
3. Cold isostatic latsa: Cold isostatic latsa ya ƙunshi aikace-aikace na uniform karfi ga kore jiki, haifar da uniform yawa rarraba. Wannan fasaha yana inganta aikin samfur sosai kuma ya dace da samar da kayan aiki na silicon carbide yumbu.
4. Gel gyare-gyaren gyare-gyaren: Gel allura gyare-gyaren sabon abu ne kusa da hanyar gyare-gyaren girman net. Koren jikin da aka samar yana da tsari iri ɗaya da ƙarfi mai ƙarfi. Za a iya sarrafa sassan yumbura da aka samu ta injuna daban-daban, wanda ke rage farashin sarrafawa bayan an gama. Yin gyare-gyaren gel ɗin gel ɗin ya dace musamman don kera yumbu na siliki carbide tare da sifofi masu rikitarwa.
Ta amfani da waɗannan hanyoyin ƙirƙira, masana'anta na iya samun ingantattun yumbu na siliki carbide tare da ingantattun kayan inji da ballistic. Ƙarfin samar da yumbu na siliki carbide a cikin nau'i-nau'i da nau'i-nau'i yana ba da damar gyare-gyare da haɓakawa don saduwa da ƙayyadaddun buƙatun aikace-aikace daban-daban.
Bugu da ƙari, ƙimar farashi na siliki carbide yumbura yana ƙara sha'awar sa azaman babban aiki mai jurewa ballistic. Wannan haɗe-haɗe na kyawawan kaddarorin da farashi mai ma'ana yana sanya yumbu na siliki carbide ya zama mai ƙarfi a cikin sararin sulke na jiki.
A ƙarshe, yumbu na silicon carbide sune manyan kayan ballistic saboda kyawawan kaddarorin su da hanyoyin gyare-gyare masu yawa. Tsarin lu'ulu'u, ƙarfi, taurin, juriya, juriya na lalata, haɓakar zafin jiki da juriya mai zafi na yumbu na silicon carbide ya sa su zama zaɓi mai ban sha'awa ga masana'antun da masu bincike. Tare da fasahohin ƙirƙira iri-iri, masana'anta na iya keɓance yumbu na silicon carbide don saduwa da takamaiman aikace-aikacen, tabbatar da ingantaccen aiki da kariya. Makomar silicon carbide ceramics yana da ban sha'awa yayin da suke ci gaba da haɓakawa da yin aiki mai kyau a fagen kayan ballistic.
Dangane da kariyar ballistic, haɗuwa da zanen gadon polyethylene da abubuwan saka yumbu sun tabbatar da tasiri sosai. Daga cikin zaɓuɓɓukan yumbu iri-iri da ake da su, silicon carbide ya jawo hankali sosai a gida da waje. A cikin 'yan shekarun nan, masu bincike da masana'antun suna yin binciko yuwuwar yumburan siliki carbide a matsayin babban abu mai jurewa ballistic saboda kyawawan kaddarorin sa da ƙarancin farashi.
Silicon carbide wani fili ne da aka kafa ta hanyar tara Si-C tetrahedrons, kuma yana da nau'ikan crystal guda biyu, α da β. A yanayin zafin jiki da ke ƙasa da 1600 ° C, silicon carbide yana wanzuwa a cikin nau'in β-SiC, kuma lokacin da zafin jiki ya wuce 1600 ° C, silicon carbide yana canzawa zuwa α-SiC. Haɗin haɗin gwiwar α-silicon carbide yana da ƙarfi sosai, kuma yana iya kiyaye haɗin gwiwa mai ƙarfi ko da a yanayin zafi.
