Ngokombono wabantu, i-ceramic ithambile.Kodwa-ke, ngemva kokucubungula ubuchwepheshe besimanje, i-ceramics "iguquliwe", ibe yinto entsha eqinile, enamandla amakhulu, ikakhulukazi emkhakheni wezinto ezingenanhlamvu ezinezakhiwo ezikhethekile ezibonakalayo, i-ceramics iyakhanya, ibe yinto ethandwa kakhulu ye-bulletproof.
①Isimiso sokuvikela izinhlamvu ze-ceramic
Umgomo oyisisekelo wokuvikela izikhali ukusebenzisa amandla e-projectile, wehlise ijubane, futhi uwenze angabi nangozi.Izinto eziningi zobunjiniyela bendabuko, njengezinto zensimbi, zimunca amandla ngokuguqulwa kwepulasitiki kwesakhiwo, kuyilapho izinto zobumba zimunca amandla ngenqubo yokuchotshozwa okuncane.
Inqubo yokumunca amandla yezitsha zobumba ezingangenwa izinhlamvu zingahlukaniswa cishe izigaba ezintathu:
(1) Isigaba sokuqala somthelela: I-projectile ithinta indawo yobumba, yenza i-warhead ibe buthuntu futhi imunce amandla ngesikhathi senqubo yokuchotshozwa nokwenza izingcezu ezincane neziqinile endaweni yobumba;
(2) Isiteji sokuguguleka: I-projectile ebuthuntu iyaqhubeka nokuguguleka indawo eyizicucu, yenza ungqimba oluqhubekayo lwezingcezu zobumba;
(3) Izigaba zokuguquguquka, ukuqhekeka, kanye nokuphuka: Ekugcineni, ukucindezeleka okuqinile kukhiqizwa ku-ceramic, okubangela ukuba liphihlize.Kamuva, ipuleti elingemuva liyakhubazeka, futhi wonke amandla asele amuncwa ukuwohloka kwempahla yepuleti elingemuva.Ngesikhathi senqubo yomthelela we-projectile kuma-ceramics, kokubili i-projectile ne-ceramics yonakaliswa.
②Izimfuneko zezinto ezibonakalayo zezitsha zobumba ezingangenwa izinhlamvu
Ngenxa yokuqina kwe-ceramic ngokwayo, iyaphuka lapho ithintwa i-projectile kunokuba i-plastic deformation.Ngaphansi kwesenzo somthwalo oqinile, ukuphuka kuqala kwenzeka ezindaweni ezihlukahlukene ezifana nama-pores kanye nemingcele yokusanhlamvu.Ngakho-ke, ukuze kuncishiswe ukugxilwa kokucindezeleka okuncane kakhulu, izitsha zobumba zempi kufanele zibe sezingeni eliphezulu ezine-porosity ephansi (kufika ku-99% yenani lokuminyana kwethiyori) kanye nesakhiwo sokusanhlamvu esihle.
| Impahla | Umthelela ekusebenzeni kokuvikela inhlamvu |
| Ukuminyana | Ikhwalithi yesistimu yezikhali |
| Ukuqina | Izinga lomonakalo ku-projectile |
| I-modulus ye-elasticity | Ukudluliselwa kwamagagasi okucindezeleka |
| Ukuqina | Ukumelana nokushaywa okuningi |
| Ukuqina kokuphuka | Ukumelana nokushaywa okuningi |
| Iphethini yokuphuka | Ikhono lokumunca amandla |
| I-Microstructure (usayizi wokusanhlamvu, isigaba sesibili, ukuguqulwa kwesigaba noma i-amorphous (i-stress-induced), i-porosity) | Ithinta konke ukusebenza okuchazwe kukholamu yesokunxele |
Izakhiwo zezinto kanye nemiphumela yazo kuzakhiwo ezingangenwa izinhlamvu
Ubuningi be-silicon carbide ceramic density buphansi uma kuqhathaniswa, ubulukhuni obuphezulu, i-ceramic yesakhiwo engabizi kakhulu, ngakho-ke iphinde ibe yi-ceramic evikela izinhlamvu esetshenziswa kakhulu eChina.
I-Boron carbide ceramics inobukhulu obuphansi kakhulu nobulukhuni obuphezulu kakhulu phakathi kwalezi zixhobo zobumba, kodwa ngesikhathi esifanayo, izidingo zabo zokucubungula ubuchwepheshe nazo ziphakeme kakhulu, ezidinga izinga lokushisa eliphezulu nokucindezela okuphezulu, ngakho-ke izindleko nazo ziphakeme kakhulu phakathi kwalezi zitsha zobumba ezintathu.
