Mu kiganiro kirekire hagati y'abantu n'ibikoresho birinda,ibumba rya karubide rya silikoniirimo gusubiza igitekerezo cy’iteka cyo kurinda umutekano mu ijwi ridasanzwe. Iyi ceramic isa n’iy’umukara isa n’iy’imvi isanzwe irimo gukora inkuru igezweho yo “kwihangana no koroha mu guhangana n’ubukana” mu nzego zigezweho nko mu nganda za gisirikare no mu kirere.
Amategeko agenga uburinzi bwa silicon carbide ceramics ari mu isi yayo ntoya. Iyo ikuze igera kuri nanoscale, imiterere myinshi myiza ya tetrahedral iba imeze nk'udukingirizo twa Lego twakusanyijwe neza, kandi uru rusobe rw'imiterere itatu rutuma ibikoresho bikomera kandi bikomeye bidasanzwe. Iyo isasu rikoze ku buso, uru rusobe rushobora gukora nk'"isoko y'ingirabuzimafatizo", rukagabanya imbaraga z'ingufu, rukirinda gucika no kwangirika kw'ibyuma gakondo kandi rugatsinda intege nke z'ibikoresho bisanzwe bya ceramics bishobora kwangirika.
Ugereranyije n'ibikoresho bisanzwe bidashobora kwinjizwamo amasasu, ubu bwoko bushya bw'ibumba bufite "imiterere ibiri" yihariye. Ubukomere bwayo bushobora guhwana n'ubwa diyama, ariko uburemere bwayo ni kimwe cya gatatu cy'icyuma. Iyi miterere y' "ubwoya nk'ubw'umukara" ituma ibikoresho birinda bishobora kugera ku ntambwe nyayo mu kugabanya ibiro. Igitangaje kurushaho ni uko nyuma yo kwihanganira ingaruka zikomeye, idasiga imbaraga zica imbere nk'uko ibyuma bibigenza, kandi iyi miterere "yo kudaharira" yongera cyane ubwizerwe bw'ibikoresho.
Muri laboratwari, icyuma cya silikoni cya karubide kirimo gupimwa. Iyo icyuma kiregereye ku muvuduko wa metero 900 ku isegonda, ibishashi biturika iyo bihuye nacyo biba bimeze nk'umuriro ugaragara mu isi ya mikorosikopi. Muri iki gihe, ubuso bwa ceramic butangira kugaragaza "ubuhanga bwa Tai Chi": ubwa mbere, binyuze mu gukomera cyane k'ubuso, icyuma kirekuye kiragabanuka; hanyuma, imiterere y'ubuki ikwirakwiza umuraba wo gukubita mu mpande zose; amaherezo, binyuze mu guhindura pulasitiki kw'ibikoresho bya matrix, ingufu zisigaye zinjiramo burundu. Ubu buryo bwo kwirinda urwego ku rundi busobanura neza ubuhanga bw'ikoranabuhanga rigezweho ryo kurinda.
Abahanga mu by’ibikoresho baracyashakisha andi mahirwe menshi: binyuze mu gushushanya bionics kugira ngo bigane imiterere y’ibikonoshwa, gushyiramo imigozi y’ubwenge mu matrix ya ceramic, ndetse no kugerageza gutuma ibikoresho bifite ubushobozi bwo kwisana. Ubu bushya ntibutera imbere gusa mu ikoranabuhanga ryo kurinda ahubwo bunasobanura neza icyo "umutekano" ugezweho.
Kuva ku ntwaro z'umuringa z'abasirikare ba kera kugeza ku byuma bito bito binini byo muri iki gihe, abantu bakomeje gushaka uburyo bwo kurinda umutekano. Inkuru y'iterambere rya silicon carbide ceramics itubwira iti: Uburinzi bukomeye cyane akenshi buturuka ku mategeko ahambaye cyane y'ibidukikije, kandi iterambere mu bumenyi bw'ibikoresho mu by'ibanze ni imbyino nziza ijyanye n'amategeko agenga fiziki.
