Titanium thiab nws cov alloys yog heev haum rau siv nyob rau hauv aircraft, missiles, foob pob ua ntxaij, thiab lwm yam high-ceev aircraft vim lawv tsis tshua muaj ceev (4.51g / cm3), siab zog (qee yam mus txog 1000MPa), siab tshwj xeeb zog, zoo heev thiab Kev ua haujlwm kub qis (- 250 degree ~ 500 degree) thiab qaug zog tiv thaiv (kev qaug zog yog ob npaug ntawm cov hlau). Cov nyhuv txo qhov hnyav uas tsim los ntawm daim ntawv thov ntawm titanium alloy fasteners yuav muaj kev cuam tshuam loj rau kev txhim kho lub propulsion ntawm aircraft thiab spacecraft, nce ntau yam, txuag roj, txo tus nqi pib, thiab lwm yam nyob rau hauv niaj hnub aircraft manufacturing, kev sib txuas fasteners siv los ntawm ib tug. dav hlau ntau los ntawm ntau pua txhiab mus rau lab.Titanium alloy fastenersaccount rau 90 feem pua ntawm threaded fasteners. Titanium fasteners tau dhau los ua qhov tseem ceeb tshaj plaws "aerospace fasteners".
Titanium alloy fastenersmuaj kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nws cov peev xwm ua tau zoo tsuas yog sib tw nrog carbon fiber ntau, uas tiv thaiv cov galvanic corrosion ntawm fasteners. Yog li ntawd, titanium fasteners tuaj yeem siv rau kev sib txuas ntawm cov qauv titanium, cov qauv txhuas, s, thiab txawm tias qee cov ntaub ntawv sib xyaw. Cov yam ntxwv no tsis tuaj yeem hloov tau los ntawm lwm cov ntaub ntawv, uas tseem yog kev txhim kho sai ntawm titanium fasteners.
Titanium muaj kev ruaj ntseg tshwj xeeb hauv cov dej hiav txwv zoo li qub lossis kev kub ceev vim nws qhov kev tiv thaiv corrosion zoo dua li txhua yam hlau. Tsis tas li ntawd, cov fasteners ua los ntawm titanium alloy yog heev haum rau kev siv nyob rau hauv submarines, warships, pej xeem ships, thiab desalination li.
Industrial teb ntawm ib puag ncig corrosive heev
Hauv cov chaw tsim khoom thiab cov khoom siv hauv cov roj av, tshuaj lom neeg, metallurgy, hluav taws xob fais fab, thiab lwm yam kev lag luam, fasteners thiab connectors yuav tsum tsis tsuas yog dais ib qho load, tab sis kuj yuav muaj zog corroded los ntawm ntau yam kua qaub thiab alkali xov xwm. Cov xwm txheej ua haujlwm hnyav heev. Kev siv ntawmtitanium alloy fastenersyog qhov kev xaiv zoo tshaj plaws.
Vim tias titanium muaj zog heev corrosion kuj nyob rau hauv high-temperature thiab ntub chlorine ib puag ncig. Piv txwv li, tus nqi corrosion ntawm titanium nyob rau hauv ib txwm kub chlorine dej yog 0.000565mm/a; Hauv dej chlorine ntawm 80 degree, tus nqi corrosion yog 0.00431mm / a; Hauv 95 feem pua cov dej chlorine ntub dej, tus nqi corrosion yog 0.00096mm / a. Yog li ntawd, titanium fasteners yog qhov zoo tshaj plaws lwm txoj rau stainless hlau fasteners.
