Kubva muzana ramakore rechi21, mararamiro asingapindi mabara akakura nekukurumidza aine mamwe marudzi, anosanganisira Alumina, Silicon Carbide, Boron carbide, Silicon Nitride, Titanium Boride, nezvimwewo. Pakati pazvo, Alumina Ceramics (Al2O3), Silicon Carbide ceramics (SiC) neBoron Carbide Ceramics. (B4C) ndiyo inonyanya kushandiswa.
Alumina Ceramics ane kusimba kwakanyanya, asi kuomarara kwakaderera, kuderera kwekugadzirisa, uye mutengo wakaderera.
Silicon carbide ceramics ine yakaderera density uye kuomarara kwakanyanya uye inodhura-inoshanda zvimiro zvekeramics, saka ndiwo zvakare anonyanya kushandiswa bulletproof ceramics muChina.
Boron carbide ceramics mumhando idzi dzeceramics mune yakaderera density, iyo yakanyanya kuoma, asi panguva imwechete iyo inogadziriswa zvinodiwa zvakare yakanyanya kukwirira, inoda tembiricha yepamusoro uye yakanyanya-kudzvanywa sintering, uye nekudaro mutengo uriwo wepamusoro pakati pezvitatu izvi. Ceramics.
Mukuenzanisa yezvitatu izvi zvinozivikanwa zve ballistic ceramic materials, Alumina ballistic ceramic cost ndiyo yakaderera asi kuita kwe ballistic kwakaderera zvikuru kune silicon carbide uye boron carbide, saka iko zvino kupihwa kweballistic ceramic kazhinji kacho silicon carbide uye boron carbide bulletproof.
Silicon carbide covalent bonding yakasimba zvakanyanya uye ichiri nepamusoro pesimba rekubatana pakupisa kwakanyanya. Ichi chimiro chechimiro chinopa silicon carbide ceramics simba rakanakisa, kuomarara kwakanyanya, kusagadzika kwekusapfeka, corrosion resistance, high thermal conductivity, good thermal shock resistance and other properties; panguva imwecheteyo, silicon carbide ceramics ine mwero mutengo uye inodhura-inoshanda, uye ndeimwe yeanonyanya kuvimbisa yakakwirira-inoshanda ekudzivirira zvombo. SiC ceramics ine nzvimbo yakakura yebudiriro mumunda wekudzivirira kwezvombo, uye mashandisirwo acho anowanzo kuve akasiyana munzvimbo dzakadai semidziyo inotakurika nevanhu uye mota dzakakosha. Sechinhu chekudzivirira chezvombo, tichifunga nezvezvinhu zvakaita semutengo uye mashandisirwo akasarudzika, mitsara midiki yeceramic mapaneru inowanzobatanidzwa neyakaumbwa inotsigirwa kuti iumbe ceramic composite inotangwa mahwendefa kukurira kutadza kweceramics nekuda kwekushushikana kwekushushikana uye kuve nechokwadi chekuti chidimbu chimwe chete. inopwanyika pasina kukuvadza nhumbi dzokurwa dzose kana projectile inopinda.
Boron carbide inozivikanwa sechinhu chechitatu chakaomesesa mushure medhaimondi uye cubic boron nitride, nekuoma kunosvika 3000 kg/mm2; low density, chete 2.52 g/cm3, ; yakakwirira modulus ye elasticity, 450 GPa; coefficient yayo yekuwedzera kwekushisa yakaderera, uye kupisa kwekushisa kwakakwirira. Mukuwedzera, boron carbide ine kugadzikana kwakanaka kwemakemikari, asidhi uye alkali corrosion resistance; uye nehuwandu hwesimbi yakanyungudutswa hainyorove uye haipindirani. Boron carbide ine zvakare yakanaka kwazvo neutron absorption kugona, iyo isingawanikwe mune zvimwe zve ceramic zvinhu. Iyo density yeB4C ndiyo yakaderera pane akati wandei anowanzo shandiswa ezvombo ceramics, uye yakakwira modulus yekunyungudika inoita kuti ive sarudzo yakanaka yezvombo zvehondo uye nzvimbo yemunda zvinhu. Matambudziko makuru neB4C mutengo wayo wepamusoro uye brittleness, iyo inodzikamisa kushandiswa kwayo kwakafara senhumbi dzekudzivirira.
