Sintered silicon carbide ceramics thiab silicon carbide ceramic bulletproof khoom series

Cov Khoom Siv SiC Uas Sintered: Cov Zoo ntawm SiC Ceramic Ballistic Products

Cov khoom siv tiv thaiv kab mob silicon carbide ceramictab tom nrov zuj zus hauv kev tiv thaiv tus kheej thiab tub rog vim lawv qhov kev ua tau zoo thiab kev ua tau zoo heev. Cov khoom siv ceramics no muaj cov ntsiab lus SiC ≥99% thiab qhov nyuaj (HV0.5) ≥2600, ua rau lawv yog cov khoom siv xaiv rau cov ntawv thov ballistic xws li cov tsho tiv thaiv mos txwv thiab cov khoom siv tiv thaiv rau cov tank thiab cov tsheb armored.

Cov khoom tseem ceeb ntawm cov koob no yog silicon carbide ceramic bulletproof sheet. Nws qhov ceev tsawg thiab lub teeb yuag ua rau nws haum rau cov tub rog cov khoom siv bulletproof, tshwj xeeb tshaj yog ua sab hauv ntawm cov tsho tiv thaiv bulletproof. Tsis tas li ntawd, nws muaj cov txiaj ntsig zoo hauv kev ruaj khov, lub zog thiab kev ruaj khov thermal.

Cov khoom siv ua los ntawm silicon carbide (SiC) muaj ob lub qauv siv lead ua, cubic β-SiC thiab hexagonal α-SiC. Cov khoom siv ua los ntawm cov khoom no muaj covalent bonds muaj zog, cov khoom siv kho tshuab zoo dua, tiv taus oxidation, tiv taus hnav thiab coefficient ntawm kev sib txhuam qis dua li lwm cov khoom siv ua los ntawm alumina thiab boron carbide. Lawv cov thermal conductivity siab, coefficient ntawm thermal expansion me me, thiab tiv taus zoo heev rau thermal shock thiab tshuaj corrosion ntxiv ua rau lawv siv tau dav.

Lub hauv paus ntsiab lus tiv thaiv mos txwv ntawm silicon carbide ceramics yog nws lub peev xwm los rhuav tshem thiab nqus lub zog mos txwv. Thaum cov ntaub ntawv engineering ib txwm nqus lub zog los ntawm kev hloov pauv yas, cov ntaub ntawv ceramic, suav nrog silicon carbide, ua li ntawd los ntawm microfractures.

Cov txheej txheem nqus zog ntawm silicon carbide bulletproof ceramics muaj peb theem. Thaum lub sijhawm pib sib tsoo, lub mos txwv ntaus rau ntawm qhov chaw ceramic, ua rau lub mos txwv tsis muaj zog thiab tsoo qhov chaw ceramic, tsim cov cheeb tsam me me, tawv tawg. Thaum lub sijhawm erosion, lub mos txwv blunt txuas ntxiv eroded thaj chaw khib nyiab, tsim ib txheej txuas ntxiv ntawm cov khib nyiab ceramic. Thaum kawg, thaum lub sijhawm deformation, tawg thiab tawg, cov ceramic raug kev nyuaj siab tensile, ua rau nws tawg. Lub zog seem tom qab ntawd raug tshem tawm los ntawm kev deformation ntawm cov khoom siv backplate.

Cov khoom zoo heev no thiab cov txheej txheem nqus zog peb theem ua rau cov khoom siv silicon carbide ceramic ballistic tuaj yeem txo qhov cuam tshuam ntawm cov mos txwv thiab ua rau lawv tsis muaj teeb meem. Qhov ntsuas tiv thaiv mos txwv ncav cuag American standard theem 4, uas muab kev tiv thaiv siab tshaj plaws thiab yog thawj qhov kev xaiv ntawm cov kws tshaj lij tub rog hauv ntiaj teb.

Hauv kev xaus lus, cov khoom siv sintered silicon carbide ceramics thiab silicon carbide ceramic bulletproof series muaj cov txiaj ntsig tshwj xeeb hauv cov khoom siv kho tshuab, thermal stability, thiab bulletproof efficiency. Nrog lawv cov khoom zoo tshaj plaws, cov ceramics no tau siv dav ua cov ntaub ntawv hauv pem teb rau cov tsho tiv thaiv bulletproof thiab cov khoom siv tiv thaiv rau cov tank thiab cov tsheb armored. Lawv qhov ceev qis thiab qhov hnyav ua rau lawv zoo tagnrho rau kev tiv thaiv ballistic tus kheej. Raws li thev naus laus zis txuas ntxiv mus, peb tuaj yeem cia siab tias yuav muaj kev txhim kho ntxiv thiab kev siv ntawm cov khoom siv ceramics zoo kawg no hauv kev tiv thaiv tus kheej thiab tub rog.
