Titanium yog cov khoom siv zoo tshaj plaws nyob rau hauv marine ib puag ncig. nws txoj kev siv tuaj yeem txhim kho kev sib ntaus sib tua zoo, txo cov nqi tu, ua kom lub neej ntev thiab txhim kho kev zais ntawm cov nkoj tub rog thiab cov khoom siv.
nws tau siv dav hauv siab-cov plhaub tiv thaiv, cov kav dej hiav txwv, cov khoom siv loj thiab lwm yam khoom ntawm cov dej hauv qab dej, cov nkoj hauv qab dej, cov nkoj ntog, nkoj thiab lwm yam khoom siv los ntawm Lavxias, Asmeskas thiab Suav navies.
Pressure resistant hull
Muaj ntau ntau yam piv txwv ntawm kev siv titanium raws li siab- resistant hull nyob rau hauv tsev thiab txawv teb chaws, uas yog tsuas yog siv nyob rau hauv sib sib zog nqus submarine manned spherical thiab submarine hull.Ti-6A1-4V, Ti-6A1-4VELI (suav nrog rau lub domestic hom TC4 thiab TC4ELD) yog qhov kev xaiv loj ntawmcov ntaub ntawv titaniumrau sib sib zog nqus submersible manned spherical hull nyob rau hauv tsev thiab txawv teb chaws. Ntau qhov sib sib zog nqus submersible manned spherical hull siv hlau nyob rau theem pib, tab sis lawv tau hloov los ntawm cov ntaub ntawv titanium nyob rau theem tom ntej, uas tuaj yeem txo qhov hnyav, nce qhov tob ntawm submersion thiab ua kom lub neej kev pab cuam.
For example: (1) The US Alvin deep submersible was constructed in 1964 with HY100 high strength steel (33.8m m plate thickness) and a submergence depth of 2000 m. When it was reconstructed in 1973, the pressure-resistant hull was replaced with titanium alloy (49m m plate thickness), the submergence depth increased to 3600 M. Ti-6A1-4VELI was also used for its auxiliary box and high-pressure air vehicle; (2) Japan's "Deep Sea 2000" manned spherical hull were prepared by rust-flipping, followed by the construction of "Deep Sea 6500" using titanium materials to prepare manned spherical shells to increase the depth of submergence.
Nyob rau hauv daim ntawv thov ntawm submarine siab hull, Russia xaiv titanium materia ua cov khoom ntxov tshaj plaws. Nws yog lub teb chaws tshaj plaws thiab paub tab nyob rau hauv lub ntiaj teb no siv titanium los ua lub siab hull. Lub xwbcov khoom siv titaniumxaiv rau tag nrho -titanium nuclear submarine manufacturing yog IIT-3B titanium alloy (xws li tus lej TA17). Nyob rau hauv xyoo tas los no, nws kuj tseem nyiam nyob rau hauv kev tsim cov submarines hauv Suav teb. Cov hom lag luam feem ntau tsom rau TA17, TC4, TC4ELI, TC11, ntshiab titanium, thiab lwm yam.
In addition, many countries are currently building large-depth manned submersibles and large-depth all-titanium weapons and equipment. The domestic "Fighter" deep-sea manned submersible successfully challenged the deepest Mariana trench in the world on November 10, 2020, reaching a depth of 1090m, fulfilling the Chinese deep-sea dream. The manned spherical shell of the deep-sea submersible is made of high strength, high toughness and damage tolerance titanium alloy.
