Vim nws qhov ceev tau zoo tshaj plaws thiab cov txheej txheem lub zog, titanium alloys pom dav dav hauv ntau lub teb, kho tshuab, txawm nws yog lub tshuab luam ntawv lossis tshuab luam ntawv. Tshwj xeeb hauv kev lag luam aerospace, titanium alloys tuav txoj haujlwm tseem ceeb thiab ua haujlwm tseem ceeb ntawm cov khoom siv.
Nrog rau kev loj hlob tsis tu ncua hauv aerospace thiab kev lag luam tiv thaiv, qhov kev thov rau kev tsim khoom yuav nce ntxiv. Tsis tas li ntawd, kev xaiv cov khoom siv yog qhov tseem ceeb hauv kev tsim rau kev siv dav hlau thiab kev tiv thaiv. Rau cov khoom tawm hauv av, txo cov khoom siv thiab txo qhov hnyav yog qhov tseem ceeb. Hauv cov cheeb tsam no, txhua gram txo qhov hnyav ua rau muaj txiaj ntsig zoo.
Hauv cov ntsiab lus, siv titanium ua cov khoom siv rau aerospace muaj ntau yam zoo:
Strength-to-weight ratio:Hauv cov xwm txheej tseem ceeb uas txhua gram ntawm cov khoom tseem ceeb, titanium yog qhov kev xaiv zoo tshaj plaws thaum xav tau cov khoom siv zog ntau dua. Li no, titanium alloys yog ua hauj lwm nyob rau hauv kev tsim cov khoom kho mob / cog, complex satellite Cheebtsam, fixtures, thiab kev txhawb nqa.
Tus nqi:Txawm hais tias tus nqi siab ntawm titanium, nws propels muaj nuj nqis leaps. Cov khoom sib sib zog nqus uas nws muab rau lub dav hlau lossis lub dav hlau ua rau muaj kev txuag roj tseem ceeb, thiab cov khoom siv titanium alloy muab lub neej ntev dua.
Kev ua haujlwm kub:Titanium lub siab melting point ua rau nws haum rau high-temperature daim ntaub ntawv, uas muaj xws li ib tug ntau yam ntawm titanium alloy Cheebtsam nyob rau hauv lub aircraft engine.
Corrosion kuj:titanium exhibits zoo heev corrosion kuj. Nws tsis kam mus corrosion thiab tsis tshua muaj reactivity ua rau nws cov biocompatible hlau feem ntau, dav siv nyob rau hauv kev kho mob teb zoo li cov cuab yeej phais. Ti64, piv txwv li, kuj ua tau zoo tiv thaiv ib puag ncig dej ntsev thiab nquag siv hauv kev siv dej hiav txwv.
Titanium alloys muaj lub zog siab thiab qhov ntom ntom, kwv yees li 57% ntawm cov hlau. Cov yam ntxwv no ua rau lub zog-rau-hnyav piv rau lwm cov khoom siv hlau, tso cai rau kev tsim cov khoom uas muaj zog thiab hnyav. Titanium alloys yog siv nyob rau hauv ntau yam aircraft Cheebtsam xws li engine qhov chaw, lub moj khaum, daim tawv nqaij qauv, fasteners, thiab tsaws iav.
Titanium muaj qhov siab melting point, siab tshaj 1600 degree, ua rau nws nyuaj rau cov txheej txheem, uas yog ib qho ntawm cov laj thawj tseem ceeb rau nws cov nqi siab dua piv rau lwm cov hlau. titanium alloy cov ntaub ntawv tsis tsuas yog lub teeb yuag, tab sis kuj muaj lub zog siab thiab kub-resistant, ua rau lawv xav tau heev hauv kev lag luam aerospace.
Cov ntawv thov feem ntau suav nrog kev tsim cov hniav, discs, casings, thiab lwm qhov chaw rau cov kiv cua ntawm lub cav thiab cov compressors uas ua haujlwm nyob rau hauv qhov chaw kub qis, xws li ntawm 400-500 degree . Tsis tas li ntawd, titanium yog siv rau hauv kev tsim cov fuselage thiab spacecraft Cheebtsam, foob pob ua ntxaij cav casings, helicopter rotor hubs, thiab lwm yam.
Txawm li cas los xij, txawm tias nws qhov kub thiab txias tsis kam tiv thaiv corrosion, titanium muaj cov hluav taws xob tsis zoo, ua rau nws tsis tsim nyog rau kev siv hluav taws xob. Tsis tas li ntawd, titanium alloys kim dua piv rau lwm cov hlau hnyav xws li txhuas.
