Hauv kev tiv thaiv niaj hnub no, nrog kev txhim kho txuas ntxiv ntawm riam phom lub zog, cov kev xav tau ntawm cov khoom siv phom sij tau dhau los ua nruj.Silicon carbide, zoo li cov khoom siv zoo tib yam tab sis muaj zog heev, maj mam tawm los ua qhov nyiam tshiab hauv kev lag luam mos mos. Niaj hnub no, peb yuav nthuav tawm cov ntaub thaiv tsis meej ntawm silicon carbide bulletproof.
1 、 Unveiling lub ntsiab cai ntawm mos mos
Lub hauv paus ntawm kev tiv thaiv armor yog nyob rau hauv kev siv lub zog ntawm projectiles, slowing lawv mus txog thaum lawv poob lawv txaus ntshai. Cov khoom siv hlau tsoos cia siab rau cov yas deformation kom nqus tau lub zog, thaum cov ntaub ntawv ceramic ua tiav lub hom phiaj los ntawm cov txheej txheem micro crushing tshwj xeeb. Noj silicon carbide bulletproof ceramics ua piv txwv, thaum muaj kev cuam tshuam rau qhov projectile, qhov projectile ua ntej ua blunt tam sim ntawd ntawm qhov cuam tshuam nto, thiab cov nplais ceramic yog crushed los ua ib qho nyuaj fragmented cheeb tsam. Cov txheej txheem no zoo li muab qhov projectile "rauj" thiab pib nqus lub zog; Tom qab ntawd, lub blunted projectile txuas ntxiv mus rau pem hauv ntej, eroding lub fragmented cheeb tsam thiab tsim ib tug nruam txheej ntawm ceramic fragments; Thaum kawg, cov pob txha ceramics nyob rau hauv tensile kev nyuaj siab, thiab lub backplate pib deform. Lub zog ntxiv yog absorbed tag nrho los ntawm deformation ntawm cov khoom siv backplate.
2, Vim li cas silicon carbide tuaj yeem ua cov mos txwv?
Silicon carbide yog ib qho sib xyaw ua ke ntawm covalent bonds, thiab nws cov Si-C bonds tuaj yeem tuav lub zog siab ntawm qhov kub thiab txias. Cov qauv tshwj xeeb no ua rau cov khoom siv silicon carbide ceramics nrog ntau yam khoom zoo heev. Nws muaj qhov nyuaj siab heev, thib ob tsuas yog pob zeb diamond, cubic boron nitride, thiab boron carbide ntawm cov khoom siv. Nws zoo li ib tug tub rog hnav lub tsho tawv tawv, muaj peev xwm tiv taus qhov projectile; Nyob rau tib lub sijhawm, nws muaj qhov qis dua thiab muaj qhov sib dua hauv qhov hnyav thaum tsim cov khoom siv rau hauv cov khoom lag luam. Txawm hais tias nws yog rau kev sib ntaus sib tua ib leeg lossis nruab rau hauv tsheb thiab dav hlau, nws yuav tsis dhau los ua lub nra ntxiv, tab sis tuaj yeem txhim kho kev txav mus los ntawm kev sib ntaus sib tua. Tsis tas li ntawd, silicon carbide kuj muaj qhov zoo thermal stability thiab tshuaj tiv thaiv corrosion, thiab tuaj yeem ua lub luag haujlwm ruaj khov hauv ntau qhov chaw ib puag ncig.
3, Qhov tshwj xeeb zoo ntawm cov tshuaj tiv thaiv sintered silicon carbide nyob rau hauv customized qhov chaw
Hauv kev npaj cov txheej txheem ntawm silicon carbide ceramics, cov tshuaj tiv thaiv sintered silicon carbide (RBSiC) sawv tawm, tshwj xeeb tshaj yog tsim rau kev tsim khoom, rau cov laj thawj hauv qab no:
1. Kev ntom ntom ntom thiab lub zog siab: nyob rau hauv cov kev mob siab ntau, dawb carbon reacts nrog kua Silicon kom tsim cov khoom siv tshiab silicon kom tsim cov khoom tshiab silicon Nyob rau tib lub sij hawm, dawb silicon permeates thiab nyob rau hauv lub qhov hws, zoo heev nce qhov ceev ntawm cov khoom, yuav luag mus txog lub theoretical ntom. Qhov no tsis tsuas yog endows cov khoom uas zoo heev compressive thiab dabtsi yog khoov lub zog, tab sis kuj muab nws zoo hnav tsis kam, uas muaj peev xwm tiv taus siab thiab siab tej yam kev mob, ua tau raws li nruj raws li qhov yuav tsum tau ntawm customized qhov chaw rau lub zog thiab durability.
2. Controllable microstructure: Cov txheej txheem sintering cov tshuaj tiv thaiv tuaj yeem tswj tau qhov kev loj hlob ntawm cov nplej, tsim cov khoom me me thiab zoo ib yam. Qhov zoo microstructure no ntxiv txhim kho cov khoom siv dag zog ntawm cov khoom, ua kom nws nyob ruaj khov thiab tsis tshua muaj kev tawg lossis puas tsuaj thaum ntsib ntau yam kev ntxhov siab, muab cov khoom lav rau kev ntseeg siab ntawm cov khoom siv.
3. High dimensional precision: Thaum lub sij hawm densification txheej txheem, qhov seem hloov ntawm cov tshuaj tiv thaiv sintered silicon carbide yog tsawg, uas yog ib qho tseem ceeb rau customized qhov chaw. Txawm hais tias nws yog ib tug tub rog phom phom ntsaws nrog cov duab nyuaj lossis lub tsheb tshwj xeeb tiv thaiv nrog nruj me me, lawv tuaj yeem raug tsim los ua kom muaj kev sib raug zoo nrog cov khoom siv.
4. Kev ruaj ntseg tshuaj zoo: Cov tshuaj tiv thaiv sintered silicon carbide yuav luag tsis muaj qhov qhib qhov hws, ua rau nws nyuaj rau cov pa oxygen thiab cov khoom corrosive kom nkag mus rau sab hauv ntawm cov khoom, yog li muaj zog oxidation thiab corrosion kuj. Qhov no txhais tau hais tias customized silicon carbide bulletproof khoom tseem tuaj yeem tswj kev ua haujlwm ruaj khov, txuas ntxiv kev pab cuam lub neej, thiab txo cov nqi tu hauv qhov hnyav ntuj lossis tshuaj lom neeg ib puag ncig ntev.
4 、 Silicon carbide bulletproof daim ntawv thov teb
Nrog nws cov kev ua tau zoo heev, silicon carbide cov ntaub ntawv pov thawj tau siv dav hauv ntau qhov chaw:
1. Cov khoom siv ntawm tus kheej: silicon carbide bulletproof tsho khuam hauv ob sab phlu, lub kaus mom tsis muaj phom, thiab lwm yam, muab cov tub rog nrog lub teeb yuag thiab kev tiv thaiv siab, ua rau lawv yoog raws kev sib ntaus sib tua thaum muaj kev tiv thaiv kev ruaj ntseg.
2. Cov tsheb tshwj xeeb: xws li tsheb armored, tsheb thauj nyiaj ntsuab, kev tiv thaiv kev ua phem thiab kev tswj hwm kev kub ntxhov, thiab lwm yam, tau nruab nrog silicon carbide ceramic armor hauv cov khoom tseem ceeb, uas tuaj yeem tiv thaiv ntau yam riam phom tawm tsam thiab tiv thaiv kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom tseem ceeb hauv lub tsheb.
3. Aerospace: Silicon carbide bulletproof cov ntaub ntawv yog siv los ntawm armed helicopters thiab lwm yam aircraft los txo lawv tus kheej qhov hnyav, txhim kho kev ua haujlwm ntawm lub davhlau, thiab txhim kho lawv lub peev xwm los tiv thaiv cov yeeb ncuab hluav taws, ua kom muaj kev nyab xeeb ntawm kev ya davhlau.
Nrog rau kev nce qib ntawm kev siv thev naus laus zis tas li, cov ntaub ntawv silicon carbide mos txwv yuav txuas ntxiv txhim kho thiab tsim kho tshiab, tsim kom muaj zog tiv thaiv kab rau kev tiv thaiv kev nyab xeeb. Yog hais tias koj xav nyob rau hauv customized qhov chaw ntawm cov tshuaj tiv thaiv sintered silicon carbide ceramics, thov koj xav tiv tauj peb.
