Muhurukuro refu pakati pevanhu nezvinhu zvinodzivirira,zviumbwa zvesimbi zvesilicon carbideiri kupindura pfungwa isingaperi yekudzivirira kuchengetedzeka nenzwi rakasiyana. Iyi ceramic inoita kunge yakajairika yegrey-black iri kuita shanduro yemazuva ano yenyaya ye "kupfava nekuomarara" munzvimbo dzemazuva ano dzakadai seindasitiri yemauto nendege.
Kodhi yekudzivirira yesilicon carbide ceramics iri munyika yayo ine microscopic. Kana ikakudzwa kusvika pa nanoscale, maumbirwo akawanda e tetrahedral akafanana nemaLego blocks akagadzirwa nemazvo, uye network iyi yechisikigo ine mativi matatu inoita kuti zvinhu zvive zvakaoma uye zvakasimba. Kana bara rikarova pamusoro, chimiro ichi chinogona kushanda se "molecular spring", chichiisa nekunyungudutsa simba rekurova, kudzivirira kupinda uye kushanduka kwezvombo zvesimbi zvechinyakare uye kukunda kushaya simba kweceramics dzakajairika dzinogona kutsemuka.
Kana tichienzanisa nezvinhu zvechinyakare zvisingapindi mabara, rudzi urwu rutsva rweceramic runoratidza "hunhu huviri" hwakasiyana. Kuoma kwayo kunogona kukwikwidzana nedhaimani, asi huremu hwayo hunongova chikamu chimwe muzvitatu chesimbi. Hunhu uhwu hwe "kupenya seminhenga" hunoita kuti michina yekudzivirira ikwanise kubudirira mukugadzira mwenje. Chinotoshamisa ndechekuti mushure mekukunda zvakanyanya, haisiye kushushikana kwemukati kunouraya sezvinoita simbi, uye hunhu uhwu hwe "kusakanganwira" hunowedzera kuvimbika kwechinhu chacho.
Murabhoritari, ndiro yesimbi yesilicon carbide iri kuyedzwa ne ballistic. Kana projectile yasvika nekumhanya kwemamita 900 pasekondi, mapfari anoputika kana abatwa akafanana ne fireworks inoratidzwa munyika ine microscopic. Panguva ino, pamusoro pe ceramic inotanga kuratidza "hunyanzvi hwayo hweTai Chi": kutanga, kuburikidza nekuomarara kwakanyanya kwenzvimbo, projectile inogomara; ipapo, chimiro chehuchi chinoparadzira mafungu ekuvhunduka kumativi ese; pakupedzisira, kuburikidza nekushanduka kwepurasitiki kwezvinhu zve matrix, simba rasara rinonyudzwa zvachose. Iyi nzira yekudzivirira layer-by-layer inotsanangura zvakajeka uchenjeri hwetekinoroji yekudzivirira yemazuva ano.
Masayendisiti ezvezvinhu achiri kutsvaga mikana yakawanda: kuburikidza nekugadzira bionics kutevedzera chimiro chegoko, kuisa fibers dzekunzwisisa dzakangwara mu ceramic matrix, uye kutoedza kuita kuti chinhu ichi chive nehunyanzvi hwekuzvigadzirisa chega. Izvi zvitsva hazvingotungamidze kufambira mberi kwetekinoroji yekudzivirira chete asiwo zvinotsanangura patsva zvinoreva "kuchengetedzwa" kwemazuva ano.
Kubva pazvombo zvehondo zvemasoja ekare zvebronze kusvika kuzvinhu zve nanoceramics zvanhasi, kutsvaga kwevanhu dziviriro yekuchengetedza hakuna kuchinja. Nyaya yekuvandudzwa kwe silicon carbide ceramics inotiudza kuti: Dziviriro yakasimba inowanzobva mumitemo yechisikigo yakanakisisa, uye kubudirira mune zvesainzi yezvinhu chaizvoizvo kutamba kwakanaka nemitemo yepanyama.
