Sintered SiC Ceramics: Zvakanakira zveSiC Ceramic Ballistic Zvigadzirwa
Silicon carbide ceramic bulletproof zvigadzirwavari kuramba vachinyanya kufarirwa mumunda wekuchengetedzwa kwemunhu nemauto nekuda kwekuita kwavo kwakanaka uye kuita. Aya maceramics ane SiC content ≥99% uye kuoma (HV0.5) ≥2600, zvichiita kuti zvive zvinhu zvekusarudza zvekushandiswa kweballistic zvakadai semabhururu uye giya rekudzivirira rematangi nemotokari dzehondo.
Chigadzirwa chikuru cheiyi nhevedzano silicon carbide ceramic bulletproof sheet. Huremu hwayo hushoma uye huremu hwayo hunoita kuti inyatsokodzera midziyo yemasoja isingapindi bara, kunyanya seruzhowa rwemukati rwevhasi dzisingapindi bara. Uyezve, inopa zvakakosha zvakakosha maererano nekusimba, simba uye kugadzikana kwekupisa.
Silicon carbide (SiC) ceramics ine maviri makristasi zvimiro, cubic β-SiC uye hexagonal α-SiC. Aya maceramics ane yakasimba covalent zvisungo, zviri nani michina zvivakwa, oxidation kuramba, kupfeka kuramba uye yakaderera coefficient yekupokana pane mamwe maceramic akadai sealuminium uye boron carbide. Kupisa kwavo kwepamusoro kwemafuta, diki coefficient yekuwedzera kwekupisa, uye kuramba kwakanyanya kuvhundutsa kwekupisa uye kuparara kwemakemikari kunowedzera kugonesa mashandisirwo avo akasiyana-siyana.
Iyo bulletproof musimboti wesilicon carbide ceramics iri mukugona kwayo kubvisa uye kutora simba rebullet. Nepo zvechinyakare zveinjiniya zvinhu zvinotora simba kuburikidza nepurasitiki deformation, ceramic zvinhu, zvinosanganisira silicon carbide, ita izvi kuburikidza ne microfractures.
Iyo simba yekunyudza maitiro esilicon carbide bulletproof ceramics inogona kukamurwa kuita matanho matatu. Munguva yekutanga yekukanganisa, bara rinorova pamusoro peceramic, richibvisa bara uye richipwanya pamusoro peceramic, richigadzira nzvimbo diki, dzakaoma dzakatsemuka. Munguva yekukukurwa kwevhu, bullet rakagomara rinoramba richiparadza nzvimbo yemarara, richigadzira dura rinoenderera remarara e ceramic. Pakupedzisira, panguva yekuchinja, kutsemuka uye kutsemuka kwezvikamu, iyo ceramic inoiswa pasi pekunetsekana, zvichikonzera kuputika kwayo. Simba rakasara rinobva raparara ne deformation ye backplate material.
Aya akanakisa zvivakwa uye matatu-nhanho simba absorption process inogonesa silicon carbide ceramic ballistic zvigadzirwa kuti zvinyatso kudzikamisa maitiro emabara uye kuti asakuvadze. Iyo bulletproof rating inosvika kuAmerican standard level 4, iyo inopa kuchengetedzwa kwakanyanya uye ndiyo yekutanga sarudzo yemauto nyanzvi munyika.
Kupfupisa, sintered silicon carbide ceramics uye silicon carbide ceramic bulletproof chigadzirwa akateedzana ane akasiyana mabhenefiti maererano nemakanika zvivakwa, kugadzikana kwemafuta, uye bulletproof kunyatsoita. Nezvimiro zvadzo zvepamusoro, aya maceramics anoshandiswa zvakanyanya semidziyo yekumisikidza mabara uye midziyo yekudzivirira yematangi nemotokari dzehondo. Density yavo yakaderera uye huremu huremu hunoita kuti ive yakanaka kune yega ballistic dziviriro. Sezvo tekinoroji ichiramba ichifambira mberi, tinogona kutarisira kuenderera mberi uye mashandisirwo eaya anoshamisa ceramics mukudzivirira kwemunhu nemauto.
