Daim ntawv thov ntawm titanium daim hlau nyob rau hauv kev lag luam shipbuilding mas siv nws zoo heev corrosion kuj, tsawg ceev, nco, thiab tsis-magnetic zog. Titanium thiab titanium alloys yog dav siv nyob rau hauv nuclear submarines, sib sib zog nqus submersibles, atomic icebreakers, hydrofoils, hovercrafts, minesweepers, as well as propellers, nplawm antennas, seawater pipelines, condensers, heat exchangers, acoustic devices, thiab hluav taws-tua khoom. Superior. Lub ntsiab siv titanium alloys yog: industrial ntshiab titanium, Ti-SARV, Ti-6A1-4VELKTi-6Al-2Nb-Ta-0.8Mo, Ti-3AI-2.5V and Ti-3B (Ti-4A1-2V), nT- 7M(Ti{{17} }}Al-2.5Zr).
(1) Tag nrho titanium nkoj. F1 Ben muaj kev paub zoo hauv kev tsim cov nkoj titanium. Nyob rau xyoo 1990, Toho Titanium Company, Nissei Industrial Company, Fujishin Shipyard, Eto Shipyard, thiab lwm yam tag nrho ua tau tag nrho cov titanium nuv ntses nkoj los yog speedboats. Qhov zoo ntawm tag nrho cov titanium nkoj yog lub teeb yuag, ceev ceev, lub cav me me, tsis tshua muaj nqi roj, qis carbon dioxide emissions, tsis xav tau txheej txheej, thiab yooj yim tu cov ntaub ntawv txuas. Qhov tsis zoo yog cov khoom siv siab, kev ua haujlwm nyuaj thiab kev tsim khoom siv tshuab, thiab kev tiv thaiv yuav tsum tau ua. nruj. Cov txiaj ntsig ntawm lub nkoj kuaj pom tau tias lub nkoj nrawm nrawm, kev vibration thiab suab nrov ua haujlwm tau zoo heev.
(2) Atomic powered nkoj. Russia siv titanium alloy es tsis txhob stainless hlau los tsim lub nkoj chav cav, tshav kub exchangers, thiab txias kom kov yeej corrosion puas. Titanium chav cav yog dav siv nyob rau hauv cov fais fab nroj tsuag ntawm Russia lub atomic-powered icebreakers uas twb muaj lawm. Kev siv cov titanium alloy tuaj yeem txuas ntxiv lub neej kev pabcuam ntawm nws lub cav los ntawm ntau tshaj 10 zaug.
(3) Propeller. Cov khoom siv kiv cua xav tau lub zog siab, kev ua haujlwm zoo qaug zog hauv cov dej hiav txwv nruab nrab, thiab tiv thaiv kev yaig thiab cavitation corrosion. Titanium alloy tuaj yeem ua tau raws li cov kev xav tau ua tiav saum toj no. US Navy yog thawj zaug siv lub 1500mm txoj kab uas hla, plaub-hniav detachable supercavitating titanium alloy kiv cua ntawm lub nkoj hydrofoil. kuv lub teb chaws tsim hydrofoil speedboat propellers nyob rau hauv 1972. Txog tam sim no, nws tau tsim ntau yam titanium alloy propellers nrog diameters ntawm 450-1700mm. M tuaj yeem tsim kho titanium alloy propellers nrog txoj kab uas hla ntawm 1200mm thiab qhov hnyav ntawm 130kg. Kev siv mus sij hawm ntev qhia tau hais tias lub neej kev pab cuam ntawm titanium alloy propellers yog ntau tshaj tsib npaug ntawm tooj liab alloy kiv cua.
(4) Nkoj twj tso kua mis, li qub thiab cov kav dej. Vim muaj kev ua hauj lwm hnyav heev ntawm lub nkoj lub twj tso kua mis, li qub thiab cov kav dej, cov kav dej ua los ntawm tooj liab thiab stainless hlau tsuas yog muaj lub neej ntev ntawm 2-5 xyoo. Tom qab hloov nrog titanium alloy, cov nyhuv yog zoo thiab haum rau high-flow txav seawater kav. Lavxias lub neej cov qauv rau cov kav xa nkoj tau teev tseg peb xyoos ntawm qhov yuav tsum tau ua, uas yog, lub sijhawm kho thawj zaug yog 8-9 xyoo; lub neej kev pabcuam yuav tsum tsis pub tsawg tshaj 15 xyoo; thiab tag nrho lub neej yuav tsum tau muaj rau txhua chav kawm ntawm lub nkoj yuav tsum yog 25 xyoo. - Txhim khu kev lag luam rau 30 xyoo.
