Raws li ob qho khoom siv hlau, titanium alloys thiab aluminium alloys ua si tseem ceeb hauv kev lag luam, aviation, thiab tshuaj. Txawm li cas los xij, lawv muaj qhov sib txawv tseem ceeb hauv qhov ceev, lub zog, melting point, sib xyaw ua ke, uas txiav txim siab cov xwm txheej uas txhua tus siv tau.
1. Qiv thiab qhov hnyav
Titanium alloy muaj qhov ntom ntawm 4.54g \/ thaum txhuas alloy muaj qhov ntom ntom ntawm 2.7g \/ cm³. Txhuas alloys tau dav siv nyob rau hauv tsheb, tsheb kauj vab, thiab dav tsheb uas qhov hnyav txo yog yuav tsum tau vim yog lawv lub teeb yuag. Titanium alloys tau hnyav dua alloys alloys, tab sis lawv lub teeb ci ntsa iab tseem ua rau lawv zoo rau kev ua haujlwm siab xws li chaw tsim khoom thiab kho mob.
2. Lub zog thiab hardness
Titanium alloys muaj zog thiab nyuaj tshaj txhuas alloys, ua rau lawv haum rau qhov uas yuav tsum muaj zog, xws li dav hlau thiab khoom siv kho mob. Txhuas alloys, ntawm qhov tod tes, yog tsawg me ntsis muaj zog, tab sis tseem ua tau raws li qhov xav tau ntawm ntau cov ntawv thov kev niaj hnub thiab muaj kev lag luam.
3. Melting taw tes thiab kub kuj
Titanium alloys muaj ntau dua melting taw tes thiab kub ua rau muaj kev ua tau zoo heev, yog li lawv tau ua tau zoo nyob ib puag ncig xws li cov pob zeb hluav taws xob thiab dav hlau tshuab. Thaum aluminium alloys tuaj yeem tiv taus qee yam kub siab, tab sis kev ua tau zoo ntawm qhov kub siab yuav raug txo qis.
4. Corrosion tsis kam thiab oxidation tsis kam
Titanium alloy cov corrosion tsis kam thiab oxidation tiv taus heev, muaj peev xwm tawm tsam ntau yam tshuaj thiab kev tsim ntawm cov yeeb yaj kiab uas passivation. Qhov no muab titanium alloys ib qho tshwj xeeb zoo rau hauv dej hiav txwv, ntsev dej, kua qaub thiab alkali ib puag ncig. Txhuas alloys, ntawm qhov tod tes, txawm hais tias tseem muaj qee qhov kev kawm ntawm corrosion thiab oxidation tsis kam, yog qhov deb dua rau titanium alloys hauv qhov no.
5. Magnetism thiab Hluav Taws Xob Ua Haujlwm
Titanium alloy yog cov khoom siv tsis sib nqus uas tsis cuam tshuam los ntawm kev sib nqus teb thiab tsis tsim cov khoom sib nqus. Nws hluav taws xob conduction yog cov neeg tsis zoo thiab nws txoj kev tiv taus yog qhov siab. Qhov no ua rau titanium alloys tau zoo heev hauv cov ntawv thov uas xav tau cov qauv tsheb sib nqus thiab cov nyiam sib nqus levitation. Thaum aluminium alloys muaj qee qib ntawm conductivity, lawv tau tsim nyog dua titimagnetism thiab cov khoom siv hluav taws xob thiab cov khoom siv sib txuas lus.
6. Kev tsaug zog thiab cov yas
Cov tsos ntawm titanium alloy yog nyiaj-dawb, nrog nws yog xim hlau luster, thiab tsis yooj yim rau oxidize thiab hloov xim. Nws cov plasticity tseem tseem siab, tuaj yeem ua rau hauv ntau cov duab, ntau 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 thov uas xav tau kev ua kom zoo nkauj thiab cov plasticity siab. Txhuas alloys, ntawm qhov tod tes, yog me ntsis tsawg dua kev ua kom zoo nkauj, tab sis tseem ua tau zoo nyob rau hauv cov ntaub ntawv, lub qhov rooj, qhov rai, thiab teeb.
7. Kev Ua Haujlwm Siv Technological thiab Kev Ua Haujlwm
Aluminium alloy yog superior rau titanium alloy nyob rau hauv cov nqe lus ntawm cov txheej txheem thiab ua haujlwm. Aluminium alloys zoo dua nyob rau hauv cov yas, mallab nkas, weldability, weldability thiab impinability los ua txheej txheem thiab tsawg tus nqi. 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 siv tau ua tiav.
Hauv cov ntsiab lus, titanium alloys thiab txhuas alloys txhua tus muaj lawv tus kheej cov khoom tshwj xeeb thiab haum rau cov ntawv thov sib txawv. Thaum xaiv cov ntaub ntawv hlau, kev txiav txim siab kom zoo tshaj plaws yuav tsum tau ua raws li cov kev xav tau ua tau zoo thiab raug nqi. Txawm hais tias nws yog titanium alloy nrhiav kev ua tau zoo, muaj txiaj ntsig zoo thiab aluminium allocess thiab zoo, ob leeg tuaj yeem muab ua si rau lawv tus nqi tshwj xeeb hauv ntau daim teb.
