Aluminium thiab titanium alloys: lawv puas tuaj yeem hloov pauv hauv aerospace?

Qhov kev tsis sib haum xeeb ntawm aluminium alloy solenoids piv rau titanium alloy aerospace solenoids tau ua rau muaj kev cuam tshuam thoob plaws lub sijhawm thaum muaj teeb meem huab cua ntawm Boeing lub dav hlau tshiab. Kev sib cav tsis yog tsuas yog txhawj xeeb txog kev nyab xeeb ntawm lub dav hlau, tab sis kuj tseem cuam tshuam txog qhov teeb meem tseem ceeb hauv cov ntaub ntawv kev tshawb fawb: puas tuaj yeem ua cov txhuas alloys dhau los ua titanium alloys los yog tsis? Txhawm rau teb cov lus nug no, peb yuav tsum ua qhov kev soj ntsuam tob tob los ntawm ntau qhov ntev, xws li kev ua tau zoo, txheej txheem, muaj pes tsawg leeg, thiab thaj chaw siv.
Kev Sib Tham Zoo
Hauv kev ua haujlwm ntawm aerospace, qhov zoo ntawm cov ntaub ntawv yog ncaj qha ntsig txog kev ua haujlwm thiab kev nyab xeeb ntawm lub dav hlau. Titanium alloy, paub txog nws lub zog siab, tsis tshua muaj siab, corrosion kuj thiab lwm yam khoom zoo, yog cov khoom siv rau kev tsim cov dav hlau ua haujlwm siab. Nyob rau hauv sib piv, txawm hais tias aluminium alloy kuj muaj lub zog siab, nws yog qis dua rau titanium alloy nyob rau hauv cov nqe lus ntawm kub thiab corrosion kuj. Yog li ntawd, los ntawm kev pom zoo, aluminium alloys tsis tuaj yeem hloov titanium alloys.
Qhov txawv ntawm Cov Txheej Txheem
Titanium alloy yog qhov nyuaj rau kev ua haujlwm thiab yuav tsum tau ua cov cuab yeej tshwj xeeb thiab thev naus laus zis. Kev ua ntawm aluminium alloy yog qhov yooj yim thiab tus nqi qis dua. Txawm li cas los xij, qhov sib txawv ntawm cov txheej txheem no kuj tseem txiav txim siab txog lawv daim ntawv thov hauv thaj chaw aerospace. Titanium alloys yog dav siv nyob rau hauv cov khoom tseem ceeb xws li cav thiab tsaws iav vim lawv cov khoom tshwj xeeb, thaum aluminium alloys feem ntau siv nyob rau hauv cov qauv uas tsis yog-loading xws li aircraft plhaub.

Kev sib xyaw
Kev sib cav txog seb puas yog aluminium alloys tuaj yeem dhau rau titanium alloys hinges ntawm kev nkag siab ntawm cov khoom muaj pes tsawg leeg. Txawm hais tias feem ntau ntawm cov titanium alloys tam sim no siv los ntawm noob neej muaj txhuas (piv txwv li, Ti-6Al-4V alloy), qhov no tsis tau txhais hais tias aluminium alloys tuaj yeem hloov cov titanium alloys. cov ntsiab lus txhuas ntawm Ti-6Al-4V alloys suav rau ib feem me me ntawm cov hlau, thiab nws qhov kev ua tau zoo yog txiav txim siab los ntawm qhov piv ntawm titanium, aluminium thiab vanadium. Yog li ntawd, muaj qhov sib txawv tseem ceeb ntawm aluminium alloys thiab titanium alloys nkaus xwb los ntawm cov ntsiab lus ntawm kev pom.

Qhov sib txawv ntawm thaj chaw thov
Hauv kev lag luam aerospace, kev siv cov khoom sib txawv nyob ntawm qhov kev sib pauv ntawm kev ua tau zoo thiab tus nqi. Titanium alloys tau siv dav hauv cov chaw tseem ceeb vim tias lawv cov kev ua haujlwm siab, tab sis ntawm tus nqi siab dua, thaum aluminium alloys tau siv dav hauv cov qauv tsis muaj kev thauj khoom vim tias lawv cov nqi qis dua thiab kev ua haujlwm zoo dua. Qhov kev faib ua haujlwm no tsis yog kev sib tsoo, tab sis yog nyob ntawm kev xyaum ua ntev thiab kev paub dhau los.
Hauv cov ntsiab lus, aluminium alloys tsis tuaj yeem dhau los ua titanium alloys. Txawm hais tias qee qhov txhuas txhuas tuaj yeem hloov pauv cov haujlwm ntawm titanium alloys, qhov kev hloov pauv yog txwv thiab txaus ntshai hauv ib puag ncig xws li aerospace, qhov twg cov khoom siv tau zoo heev. Yog li ntawd, nyob rau hauv cov ntaub ntawv ntawm cov huab cua leakage teeb meem nyob rau hauv lub tshiab airship ntawm Boeing, peb yuav tsum tsis txhob las mees qhov tseem ceeb ntawm kev xaiv cov khoom, tab sis theej soj ntsuam kom tob thiab nrhiav kom paub qhov tseeb ntawm qhov teeb meem.
