Hlau ua npuas ncauj tsis yog cov hlau hnyav tshaj plaws thiab muaj ntau yam khoom zoo heev

Hlau ua npuas ncauj tsis yog cov hlau hnyav tshaj plaws, thiab nws qhov hardness tuaj yeem sib txawv nyob ntawm seb cov hlau muaj pes tsawg leeg thiab cov qauv pore. Piv txwv li, tungsten ua npuas ncauj tuaj yeem ncav cuag Vickers hardness ntawm 600, thaumaluminium ua npuas ncaujNws kuj yog qhov tsawg hauv hardness, feem ntau nyob ib ncig ntawm HV50. Nyob rau hauv sib piv, superhard pob zeb diamonds synthesized ntawm high pressures thiab kub yuav ncav cuag ib tug Vickers hardness txog 5,000, uas yog ntau tshaj kaum npaug ntawm hardness ntawm hlau foams.

Hlau ua npuas ncauj superior kev ua tau zoo
Txawm tiashlau ua npuas ncaujtsis yog qhov nyuaj tshaj plaws, nws tseem muaj ntau yam khoom zoo heev. Piv txwv li:
1, lub teeb yuag: vim nws cov qauv pore cov qauv, feem ntau tsawg dua 0.5 G / CM3, yog li nws tuaj yeem siv ua ib qho kev siv hluav taws xob hauv AEROSPACE thiab cov ntawv thov tsheb.
2, Muaj zog-absorbing: Lub pore qauv ntawm hlau ua npuas ncauj tso cai rau nws deform thiab nqus lub zog thaum raug lub siab, yog li nws muaj peev xwm tiv thaiv kev vibration thiab kev sib tsoo zoo heev.
3, thermal thiab hluav taws xob khoom:hlau ua npuas ncaujtuaj yeem siv ua cov rwb thaiv tsev zoo thiab cov khoom siv thermal conductivity, tab sis kuj muaj hluav taws xob zoo.
Vim yog cov khoom zoo saum toj no, hlau ua npuas ncauj muaj ntau yam ntawm daim ntawv thov kev cia siab, xws li rau tsheb poob siab-absorbing cov ntaub ntawv, aerospace structural Cheebtsam, mos mos cov ntaub ntawv, tshuaj reactors thiab lwm yam teb.
Hlau ua npuas ncauj tsis yog cov hlau hnyav tshaj plaws, tab sis nws muaj lub teeb yuag,lub zog nqus, thermal rwb thaiv tsev, thermal thiab hluav taws xob conductivitythiab ntau lwm yam khoom zoo heev, muaj ntau yam kev thov kev cia siab.
