Daim ntawv thov ntawm titanium nyob rau hauv lub tshav pob ntawm nkoj

Titanium thiab titanium alloys tau dav siv hauv ntau lub teb vim lawv cov khoom zoo heev. Lawv yog siv rau hauv cov khoom siv hauv hiav txwv xws li nuclear submarines, sib sib zog nqus- hiav txwv submersibles, nuclear-powered icebreakers, hydrofoils, hovercraft, thiab minesweepers, nrog rau cov kiv cua, nplawm antennas, seawater pipelines, condensers, heat exchangers, acoustic devices, thiab fireighting{3}.

Titanium siab hulls ua lub luag haujlwm tseem ceeb hauv kev sib sib zog nqus - hiav txwv submersibles. Cov tuam txhab tsim khoom hauv tsev thiab thoob ntiaj teb tau siv titanium siab hull tshuab rau ntau qib. Piv txwv li, US's Sea Cliff submersible yog nruab nrog titanium soj ntsuam thiab tswj module, tso cai rau nws dhia mus rau qhov tob ntawm 6100 meters. kuv lub teb chaws kuj tau ua tiav tseem ceeb hauv kev sib sib zog nqus -submersible technology, nrog nws tus kheej tsim Jiaolong submersible mus txog qhov tob tshaj 5000 meters.

Nyob rau hauv lub tshav pob ntawm submarines loj, Russia yog tib lub teb chaws uas siv titanium cov ntaub ntawv ntau. Nws rau Typhoon -chav kawm nuclear submarines feem ntau siv ntau yam titanium alloys, suav nrog kev lag luam ntshiab titanium, Ti64, Ti64ELI, Ti-6Al-2Nb-1Ta-0.8Mo, Ti-3Al-2.5V, IIT-3B, thiab IIT-7M.

1. Nuclear submarine
Russia yog ib tug thawj coj nyob rau hauv lub teb ntawm titanium alloy nuclear submarines, pioneering siv titanium alloys los tsim lub siab hulls. Ntawm nws plaub tiam ntawm nuclear submarines txij li xyoo 1960, K162, tag nrho -titanium submarine tau tsim tawm xyoo 1968, ua haujlwm rau ntau dua 30 xyoo yam tsis muaj xwm txheej. ALFA-chav kawm nuclear submarine, ua rau xyoo 1970, muaj qhov siab tshaj plaws dhia dej tob ntawm 914 meters thiab zoo heev maneuverability. Lub Typhoon-chav kawm nuclear submarine ntiav titanium ob - qauv qauv, siv 9,000 tons ntawm titanium, thiab muaj qhov zoo xws li cov khoom tsis yog{15}}sib nqus, qhov tob tob tob, thiab kev kub ceev, nrog qhov siab tshaj plaws dhia dej tob ntawm 500 meters thiab lub sij hawm tsis tu ncua ntawm 1220 hnub.

2. Tag nrho lub nkoj titanium
Xyoo 1985, Nyiv tau tsim lub "Marishiten II" tag nrho -titanium speedboat, uas muag zoo hauv Tebchaws Meskas. Nyob rau hauv 1997, lub "Titan Express" speedboat tau launched, nrog optimized hull nkhaus kom txo sailing kuj. Eto Shipbuilding tau tsim "Second Asahi Maru" thiab "Sho Maru" hauv xyoo 1998-1999, uas yog lub teeb yuag, nrawm, thiab roj-npaum, tab sis kim thiab nyuaj rau kev tsim khoom.

3. Sib sib zog nqus- hiav txwv submersibles, cawm nkoj, thiab cov khoom hauv nkoj
Tebchaws Asmeskas, Nyiv, thiab Fabkis siv cov titanium alloys los tsim lub siab hulls sib sib zog nqus - hiav txwv submersibles. Ti-6Al-2Nb-1Ta-0.8Mo alloy yog siv rau lub hulls ntawm American Aivin thiab Hiav txwv-Clifi; Ti-6Al-4V ELI alloy yog siv rau cov hulls thiab buoyancy pob ntawm Fabkis SM97, Japanese "Shinkai 2000", thiab American Deep Sea Rescue Vehicle (DSRV).

4. Jiaolong submersible
Kuv lub teb chaws Jiaolong manned submersible, nws tus kheej tsim thiab kev koom ua ke, ua tiav nws cov dej hiav txwv sim ntawm qhov tob ntawm 3,759 meters hauv 2010 thiab mus txog qhov tob ntawm 5,180 meters hauv 2011, npog 70% ntawm lub ntiaj teb seabed. Nrog rau qhov tsim qhov tob ntawm 7,000 meters thiab kev ua haujlwm ntau yam npog 99.8% ntawm thaj chaw dej hiav txwv, nws qhia tau hais tias lub teb chaws txoj kev siv tshuab muaj zog thiab txhawb nqa kev tshawb fawb hauv hiav txwv.

5. Sonar fairing
Titanium alloy sonar fairings muaj kev ua tau zoo dua thiab siv nyob rau hauv lub tshuab sonar ntawm cov nkoj xws li Lavxias "Kursk". Cov ntaub ntawv acoustic siv rau sonar fairing shells ntawm cov nkoj hauv kev pabcuam nrog Suav Navy feem ntau yog cov hlau tsis muaj steel thiab fiber ntau- siv fiberglass. Thaum lub Cuaj Hlis Tsib -Xyoo Plan lub sijhawm, kuv lub tebchaws tau tshawb fawb txog kev siv cov titanium alloys hauv nkoj sonar fairings.

6. Lub tshuab raj
Titanium alloy propellers yog tus cwj pwm los ntawm lub zog siab, tiv thaiv dej hiav txwv yaig thiab cavitation corrosion, thiab tuaj yeem ua tau raws li kev ua tau zoo. US Navy yog thawj zaug siv supercavitating titanium alloy propellers ntawm hydrofoils. kuv lub teb chaws tsim nws tus kheej hydrofoil propellers nyob rau hauv 1972 thiab tau txij li thaum tsim titanium alloy propellers nrog diameters li ntawm 450 mus rau 1200 hli, boasting ib tug kev pab cuam lub neej ntau tshaj tsib npaug ntawm tooj liab alloys.

7. Nkoj twj tso kua mis, li qub thiab cov kav dej
Shipboard twj tso kua mis, li qub, thiab cov kav dej ua haujlwm nyob rau hauv cov xwm txheej hnyav; tooj liab lossis stainless hlau piping muaj lub neej tsuas yog 2-5 xyoos, thaum titanium alloy piping ua tau zoo dua. Lavxias txoj cai lij choj hais tias cov kav xa nkoj nkoj yuav tsum tau ua haujlwm thawj zaug txhua 8-9 xyoo, muaj kev pabcuam lub neej tsawg kawg yog 15 xyoo, thiab ua haujlwm ruaj khov rau 25-30 xyoo thoob plaws nws lub neej.

8. Atomic- lub nkoj muaj zog
Russia tau hloov cov hlau tsis muaj steel nrog titanium alloys hauv kev tsim cov tshuab hluav taws xob thiab cov khoom siv hluav taws xob, kov yeej cov teeb meem corrosion. Cov atomic uas twb muaj lawm -powered icebreakers dav siv titanium chav cav, txuas lawv lub neej kev pab los ntawm kaum ob lub sij hawm.
