Cov txiaj ntsig ntawm kev siv titanium hauv kev lag luam aerospace

Titanium yog cov hlau uas muaj ntau yam khoom tsim nyog rau kev lag luam aerospace. Nws muaj zog, hnav, hnav-resistant, thiab muaj peev xwm tiv taus qhov kub thiab txias. Cov yam ntxwv no ua rau titanium yog cov khoom siv zoo tshaj plaws rau ntau yam kev siv dav hlau, foob pob hluav taws, satellites, thiab chaw tsheb.

Ib qho txiaj ntsig tseem ceeb ntawm kev siv titanium hauv kev lag luam aerospace yog nws lub zog-rau-qhov hnyav piv. Titanium yog kwv yees li 40 feem pua ​​​​sib dua li cov hlau tab sis muaj qhov sib piv lossis siab dua lub zog. Qhov no txhais tau hais tias titanium tuaj yeem txo qhov hnyav ntawm lub dav hlau lossis lub dav hlau, uas txhim kho roj efficiency, kev ua tau zoo, thiab lub peev xwm them nyiaj. Piv txwv li, Boeing 787 Dreamliner siv li ntawm 15 feem pua ​​​​titanium los ntawm qhov hnyav, uas txuag tau txog 3 lab phaus roj ib xyoos ib lub dav hlau.

Lwm qhov txiaj ntsig ntawm kev siv titanium hauv kev lag luam aerospace yog nws cov corrosion kuj. Titanium tiv taus oxidation, yaig, thiab tshuaj lom neeg los ntawm ntau qhov chaw. Qhov no ua rau titanium haum rau qhov chaw uas raug dej ntsev, av noo, acids, alkalis, thiab lwm yam corrosive agents. Piv txwv li, titanium yog siv rau cov tshuab hydraulic, tsaws iav, thiab cov khoom siv cav ntawm cov dav hlau uas ua haujlwm hauv marine ib puag ncig.

Ib qho txiaj ntsig thib peb ntawm kev siv titanium hauv kev lag luam aerospace yog nws lub peev xwm tiv taus qhov kub thiab txias. Titanium muaj qhov siab melting point ntawm 1668 degree (3034 degree F), uas yog siab dua li cov hlau feem ntau. Titanium kuj muaj cov thermal expansion coefficient tsawg, uas txhais tau hais tias nws tsis deform los yog tawg yooj yim thaum rhuab los yog txias. Qhov no ua rau titanium zoo tagnrho rau cov khoom uas raug cua sov thiab siab, xws li lub nozzles, hniav, thiab casings ntawm dav hlau cav thiab foob pob ua ntxaij.

Hauv kev xaus, titanium yog cov hlau uas muaj ntau yam txiaj ntsig rau kev lag luam aerospace. Nws muaj zog, hnav, hnav-resistant, thiab muaj peev xwm tiv taus qhov kub thiab txias. Cov khoom no ua rau titanium yog cov khoom siv zoo heev rau ntau yam kev siv dav hlau, foob pob hluav taws, satellites, thiab chaw tsheb.
