Kev sib piv ntawm Titanium Alloy thiab Aluminium Alloy Properties Thiab Daim Ntawv Thov Kev Xaiv

Raws li ob qho khoom siv hlau, titanium alloys thiab aluminium alloys ua lub luag haujlwm tseem ceeb hauv kev lag luam, aviation, thiab tshuaj. Txawm li cas los xij, lawv muaj qhov sib txawv tseem ceeb hauv qhov ntom ntom, lub zog, melting point, corrosion resistance, txheej txheem kev ua tau zoo, sib nqus thiab hluav taws xob conductivity, zoo nkauj thiab plasticity, uas txiav txim siab cov xwm txheej uas txhua tus siv tau.
1. Ceev thiab hnyav
Titanium alloy muaj qhov ceev ntawm 4.54g / cm³, thaum aluminium alloy muaj qhov ceev ntawm 2.7g / cm³. Aluminium alloys tau dav siv hauv tsheb, tsheb kauj vab, thiab dav hlau qhov yuav tsum tau txo qhov hnyav vim lawv cov khoom sib sib zog nqus. Titanium alloys hnyav dua li txhuas alloys, tab sis lawv lub teeb yuag tseem ua rau lawv zoo tagnrho rau kev ua haujlwm siab xws li lub dav hlau thiab cov khoom siv kho mob.
2. Lub zog thiab hardness
Titanium alloys muaj zog thiab nyuaj dua li aluminium alloys, ua rau lawv tshwj xeeb tshaj yog haum rau cov khoom uas yuav tsum tau muaj zog thiab hnav tsis kam, xws li lub dav hlau thiab cov khoom siv kho mob. Aluminium alloys, ntawm qhov tod tes, muaj zog me ntsis, tab sis tseem ua tau raws li qhov xav tau ntawm ntau yam kev siv niaj hnub thiab kev lag luam.

3. Melting point thiab kub tsis kam
Titanium alloys muaj qhov melting point ntau dua thiab kub tsis kam tshaj aluminium alloys, thiab muaj peev xwm tswj tau qhov kev ua haujlwm ruaj khov ntawm qhov kub thiab txias, yog li lawv ua tau zoo nyob rau hauv qhov chaw kub kub xws li foob pob hluav taws thiab lub tshuab dav hlau. Thaum aluminium alloys tuaj yeem tiv taus qee qhov kub, tab sis kev ua haujlwm ntawm qhov kub thiab txias yuav txo qis.
4. Corrosion kuj thiab oxidation kuj
Titanium alloy qhov kev tiv thaiv corrosion thiab oxidation kuj yog qhov zoo heev, muaj peev xwm tiv thaiv kev yaig ntawm ntau yam tshuaj lom neeg thiab cov tshuaj tiv thaiv electrochemical, tsim cov yeeb yaj kiab ntom ntom ntom ntom. Qhov no muab cov titanium alloys tshwj xeeb kom zoo dua hauv dej hiav txwv, dej ntsev, acid thiab alkali ib puag ncig. Aluminium alloys, ntawm qhov tod tes, txawm tias tseem muaj qee qhov kev txhim kho corrosion thiab oxidation tsis kam, yog qhov qis dua rau titanium alloys hauv qhov no.
5. Magnetism thiab hluav taws xob conductivity
Titanium alloy yog cov khoom tsis sib nqus uas tsis cuam tshuam los ntawm cov hlau nplaum thiab tsis tsim cov hlau nplaum. Nws cov hluav taws xob conductivity kuj tsis zoo thiab nws cov resistivity siab. Qhov no ua rau titanium alloys zoo heev nyob rau hauv daim ntawv thov uas yuav tsum tau muaj antimagnetic zog, xws li magnetic resonance imaging thiab sib nqus levitation tsheb ciav hlau. Thaum aluminium alloys muaj qee qhov kev coj ua, lawv tsim nyog dua li titanium alloys rau cov ntawv thov uas xav tau nruab nrab antimagnetism thiab siab conductivity, xws li cov khoom siv hluav taws xob thiab cov khoom siv sib txuas lus.
6. Aesthetics thiab plasticity
Cov tsos ntawm titanium alloy yog silver-dawb, nrog ib tug metallic luster, thiab tsis yooj yim rau oxidize thiab hloov xim. Nws plasticity kuj siab, tuaj yeem ua rau ntau yam duab, qhov ntau thiab tsawg thiab cov qauv los ntawm ntau txoj kev ua. Qhov no ua rau titanium alloys nrov rau cov hniav nyiaj hniav kub, watches, tsom iav, thiab lwm yam kev siv uas xav tau kev zoo nkauj thiab yas. Aluminium alloys, ntawm qhov tod tes, yog me ntsis aesthetically pleasing thiab malleable tshaj titanium alloys, tab sis tseem ua tau zoo nyob rau hauv nruab nrab xav tau daim ntaub ntawv xws li rooj tog, qhov rooj, qhov rais, thiab teeb.
7. Kev ua haujlwm thev naus laus zis thiab kev ua haujlwm zoo
Aluminium alloy yog superior rau titanium alloy nyob rau hauv cov nqe lus ntawm processability thiab workability. Aluminium alloys zoo dua hauv plasticity, malleability, weldability thiab machinability, tsis yooj yim rau txheej txheem thiab tus nqi qis. Ntawm qhov tod tes, titanium alloy yog qhov nyuaj rau cov txheej txheem, yuav tsum muaj cov cuab yeej tshwj xeeb thiab cov cuab yeej, thiab muaj tus nqi ua haujlwm siab.
Hauv cov ntsiab lus, titanium alloys thiab aluminium alloys txhua tus muaj lawv tus kheej cov khoom tshwj xeeb thiab qhov zoo thiab tsim nyog rau kev siv sib txawv. Thaum xaiv cov khoom siv hlau, kev txiav txim siab dav dav yuav tsum tau ua raws li cov kev xav tau ntawm kev ua tau zoo thiab kev siv nyiaj txiag zoo. Txawm hais tias nws yog titanium alloy nrhiav kev ua haujlwm siab, zoo siab thiab muaj txiaj ntsig ntxiv, lossis aluminium alloy nrhiav tus nqi qis, kev ua haujlwm siab thiab zoo, ob leeg tuaj yeem muab kev ua si rau lawv cov nqi tshwj xeeb hauv ntau qhov chaw.
