Raws li tib neeg lub neej zoo dua qub, qhov kev thov rau kev zoo nkauj thiab kev zoo hauv cov khoom tseem nce ntxiv. Ntau tus neeg siv khoom siv ntau ntxiv yog ua los ntawm cov khoom siv alloy. Cov ntaub ntawv hlau qhia qhov kev nkag siab ntawm high-end, sturdiness, thiab durability, thaum cov khoom siv yas yas yog maj mam txuam nrog cov ntawv "pheej yig" thiab "tsis zoo" nyob rau hauv lub siab ntawm cov neeg siv khoom.
Rau cov neeg siv khoom, feem ntau siv cov ntaub ntawv alloy muaj xws li aluminium alloy, zinc alloy, thiab magnesium alloy. Titanium alloy, vim nws cov biocompatibility zoo, feem ntau siv hauv kev kho mob. Hauv qab no, kuv yuav qhia cov yam ntxwv ntawm ob peb cov ntaub ntawv alloy thiab ua qhov sib piv.
kev taw qhia
Aluminium Alloy
Qhov ntom ntawm aluminium alloy yog li ntawm 2.63 txog 2.85g / cm³. Nws muaj zog dua, zoo castability, plasticity, zoo heev hluav taws xob thiab thermal conductivity, zoo corrosion kuj, thiab weldability.
Zinc Alloy
Zinc alloy muaj qhov tsis tshua muaj melting point, zoo fluidity, thiab yog yooj yim weldable. Raws li cov txheej txheem tsim khoom, nws tuaj yeem muab faib ua zinc alloy thiab wrought zinc alloy. Zinc alloy exhibits zoo heev malleability thiab ductility, feem ntau yog siv rau roj teeb casings, luam ntawv daim hlau, thiab cov khoom siv niaj hnub. Qhov ceev ntawm zinc alloy yog li ntawm 6.3 mus rau 6.7g / cm³, nrog rau qhov qis melting point ntawm 385 degree, ua rau nws yooj yim castable.
Magnesium alloy
Magnesium alloy yog ib qho alloy feem ntau muaj magnesium nrog rau lwm cov ntsiab lus ntxiv. Vim nws zoo heev casting, extrusion, txiav, thiab dabtsi yog khoov zog, magnesium alloys nrhiav kev siv dav hauv tsheb, hluav taws xob, textiles, kev tsim kho, thiab kev ua tub rog. Nrog lub melting point ntawm 650 degree, magnesium alloy muaj qis melting point piv rau aluminium alloy, muab kev ua tau zoo hauv cov txheej txheem tuag-casting. Lub zog tshwj xeeb ntawm high-strength magnesium alloys tuaj yeem sib tw ntawm titanium.
Titanium alloy
Titanium alloy hais txog ntau yam alloys ua los ntawm kev sib txuas titanium nrog lwm cov hlau. Nws muaj lub zog siab, zoo heev corrosion kuj, thiab kub kub kuj. Titanium alloys yog dav siv nyob rau hauv kev tsim khoom rau aircraft engine compressors, lub moj khaum, fasteners, tsaws iav, thiab lwm yam.
Qhov ceev ntawm titanium alloy feem ntau yog nyob ib ncig ntawm 4.51g / cm³, uas tsuas yog kwv yees li 60% ntawm cov hlau qhov ntom. Yog li ntawd, lub zog tshwj xeeb ntawm titanium alloys yog qhov siab dua li ntawm lwm cov khoom siv hlau, uas tso cai rau kev tsim cov khoom uas muaj zog rau ib chav tsev thiab lub teeb yuag, nrog zoo heev rigidity.
kev sib piv
Sib piv Table of Physical Properties
Ntawm cov plaub alloys no, titanium alloy yog qhov nyuaj tshaj plaws thiab tseem muaj lub zog siab tshaj plaws. Nyob rau hauv cov nqe lus ntawm hardness, titanium alloy yog ho nyuaj dua lwm yam peb alloys. Hais txog lub zog tensile, titanium alloy surpasses zinc alloy, ua raws li magnesium alloy, thaum aluminium alloy muaj lub zog qis tshaj.
Kev sib piv ntawm Lub Zog thiab Hardness
Txawm li cas los xij, hauv cov khoom tsim qauv, qhov hnyav kuj yuav tsum tau txiav txim siab. Thaum xav txog qhov ceev, zinc alloy, muaj qhov ceev tshaj plaws, ua tau tiag tiag muaj lub zog qis tshaj plaws-rau-hnyav piv. Titanium alloy thiab magnesium alloy qhia tau hais tias muaj zog dua, tab sis titanium alloy yog kim thiab muaj kev ua haujlwm tsis zoo. Yog li ntawd, nyob rau hauv cov khoom uas qhov hnyav thiab lub zog xav tau kev xav zoo, magnesium alloy feem ntau nyiam.
