Lokacin da aka sanya yumbu a kan "Sulke masu hana harsashi": Shiga Duniyar Kayan Silicon Carbide

A cikin dogon tattaunawa tsakanin mutane da kayan kariya,yumburan silicon carbideyana mayar da martani ga shawarar kariyar tsaro ta har abada da murya ta musamman. Wannan yumbu mai launin toka-baƙi na yau da kullun yana yin sigar zamani ta labarin "laushi da laushi akan tauri" a fannoni na zamani kamar masana'antar soja da sararin samaniya.
Lambar kariya ta yumburan silicon carbide tana cikin duniyarta mai ƙaramin ƙarfi. Idan aka ƙara girmanta zuwa sikelin nano, gine-ginen tetrahedral marasa adadi suna kama da tubalan Lego da aka haɗa daidai, kuma wannan hanyar sadarwa ta halitta mai girma uku tana ba kayan tauri da tauri mai ban mamaki. Lokacin da harsashi ya shafi saman, wannan tsarin zai iya aiki kamar "maɓuɓɓugar ƙwayoyin halitta", yana shimfidawa da narke ƙarfin tasirin, yana guje wa shiga da nakasa na sulke na ƙarfe na gargajiya da kuma shawo kan raunin yumbu na yau da kullun waɗanda ke iya fashewa.

Idan aka kwatanta da kayan gargajiya masu hana harsashi, wannan sabon nau'in yumbu yana nuna wani "halaye biyu" na musamman. Taurinsa zai iya yin gogayya da na lu'u-lu'u, amma nauyinsa kashi ɗaya bisa uku ne kawai na ƙarfe. Wannan siffa ta "haske kamar gashin fuka-fuki" tana bawa kayan kariya damar cimma nasara a fannin rage nauyi. Abin mamaki shine bayan ya jure wa mummunan tasiri, ba ya barin damuwa ta ciki kamar yadda ƙarfe ke yi, kuma wannan siffa ta "mara gafara" tana ƙara ingancin kayan sosai.
A dakin gwaje-gwaje, ana gwajin farantin yumbu na silicon carbide. Lokacin da harsashin ya kusanci da gudun mita 900 a kowace daƙiƙa, tartsatsin da ke fashewa idan aka taɓa su suna kama da wasan wuta da ake nunawa a duniyar da ba a gani ba. A wannan lokacin, saman yumbu ya fara nuna "ƙwarewar Tai Chi": da farko, ta hanyar tsananin taurin saman, harsashin ya yi kauri; sannan, tsarin zumar zuma ya yaɗa girgizar ƙasa a kowane bangare; a ƙarshe, ta hanyar nakasar filastik na kayan matrix, makamashin da ya rage yana sha gaba ɗaya. Wannan tsarin kariya na Layer-by-Layer ya fassara hikimar fasahar kariya ta zamani a sarari.
Masana kimiyyar kayan aiki har yanzu suna binciken ƙarin damarmaki: ta hanyar ƙirar bionics don kwaikwayon tsarin harsashi mai layi, saka zare masu fahimta a cikin matrix na yumbu, har ma da ƙoƙarin sanya kayan su sami damar gyara kansu. Waɗannan sabbin abubuwa ba wai kawai suna haifar da ci gaban fasahar kariya ba, har ma suna sake fasalta ma'anar zamani ta "aminci".
Tun daga sulken tagulla na tsoffin sojoji zuwa tukwanen nano na yau, neman kare lafiya na ɗan adam bai canza ba. Labarin ci gaban tukwanen silicon carbide ya gaya mana: Kariya mafi ƙarfi galibi ta samo asali ne daga mafi kyawun dokokin halitta, kuma ci gaban da aka samu a kimiyyar kayan abu ainihin rawa ce mai kyau tare da dokokin zahiri.
