Yuav ua li cas submarines cia siab rau Titanium kom ciaj sia qhov tob?

I. Qhov zoo ntawmTitanium alloyhauv submarines

Lub teeb

Raws li tib lub zog muaj zog, lub cev ntawm lub titanium alloy submarine tuaj yeem ua nyias thiab sib dua, yooj yim rhuav tshem cov kev txwv ntawm cov hlau -hulled submarines.

Corrosion Resistance

Titanium alloy forms a dense oxide film in seawater, effectively blocking the erosion of corrosive media. Nws lub neej kev pabcuam tuaj yeem txuas ntxiv mus rau ntau dua 30 xyoo, 1.5 npaug ntawm cov hlau zoo tib yam -hulled submarines. Qhov tseem ceeb tshaj, qhov kev ruaj ntseg no tso cai rau cov nkoj hauv nkoj kom nyob twj ywm rau lub sijhawm ntev yam tsis muaj kev sib tsoo rau kev saib xyuas.

Tsis yog -magnetic zog:

Titanium yog qhov sib nqus tsawg dua li hlau. Submarines siv cov khoom no yog stealthier thiab tsis tshua muaj kev cuam tshuam los ntawm kev tshawb nrhiav los ntawm cov khoom siv hlau nplaum.

II. Technological Breakthroughs ntawm Titanium Alloy Submarines

Tuam Tshoj txoj kev tshawb nrhiav thiab kev ua tiav hauv titanium alloy submarines hnub rov qab mus rau xyoo 1960 thaum txoj kev loj hlob tau teev tseg raws li qhov project tseem ceeb. Tom qab xyoo dhau los ntawm kev sib sau ua ke, Tuam Tshoj tau tsim ua tiav cov saw hlau los ntawm titanium ore mining, sponge titanium purification mus rau siab -kawg titanium alloy ua. Cov koom haum xws li Baoji Titanium Industry Co., Ltd. thiab Northwest Institute for Nonferrous Metal Research tau dhau los ua tub rog tseem ceeb hauv kev tshawb fawb thev naus laus zis. Qhov kev ua tau zoo ntawm kev lag luam no tau hloov zuj zus mus rau hauv kev dhia hauv kev ua haujlwm ntawm cov khoom siv submarine. Ntawm kev txhim kho Hom 093 thiab Hom 095 nuclear submarines, daim ntawv thov ntawm titanium alloy tau ua tiav loj - nplai tawg. Lub titanium alloy siab hull technology ntawm hom 095 nuclear submarine yog tshwj xeeb tshaj yog muaj tseeb. Kev noj titanium ib submarine tau nce 300% piv nrog rau tiam dhau los rau 120 tons. Qhov optimized TC21 (Ti-62222S) titanium alloy variant tau zoo heev txhim kho lub siab tiv thaiv thaum tswj qhov ceev ntawm 4.5 g / cm³, ua kom nws qhov tob tob tshaj 1,000 meters, deb dhau qhov kev ua tau zoo ntawm cov tsoos steel-hulled submarines.

Tuam Tshoj daim ntawv thov ntawm titanium alloy nyob rau hauv submarines tsis txwv rau lub hull tab sis tau tsim ib tug systematic qauv ntawm "tag nrho cov kev pab them nqi ntawm cov tseem ceeb Cheebtsam." Hais txog cov yam ntxwv tseem ceeb, Ti80 (Ti-6Al-3Nb-2Zr-1Mo), siab-lub zog + titanium alloy, yog siv dav hauv cov kiv cua, sonar domes, thiab lwm yam. Nws muaj kev cuam tshuam zoo heev thiab kev tiv thaiv corrosion ua kom lub sijhawm ntev - lub sijhawm ua haujlwm ruaj khov ntawm submarines nyob rau hauv txoj kev sib sib zog nqus - hiav txwv tej yam kev mob. Cov riam phom system teb tau ua tiav kev ua haujlwm thev naus laus zis. Lub torpedo hnyav tshiab tsim los ntawm Tuam Tshoj tau txais lub titanium alloy warhead, uas tsis yog tsuas yog muaj qhov tob tob tshaj 600 meters los tua cov yeeb ncuab siab heev nuclear submarines tab sis kuj dhau los ua "trump card" rau submarine stealth ua haujlwm nrog nws txoj kev -dawb thiab tsis tshua muaj suab nrov yam ntxwv. Nws tsim nyog hais tias submarine titanium alloy thev naus laus zis kuj tau ua tiav ob txoj kev txhawb nqa ntawm "kev ua tub rog-civilian kev koom ua ke." Los ntawm 7,000-meter diving titanium alloy siab hull ntawm "Jiaolong" submersible mus rau kev ywj pheej ntawm 10,000-meter manned spherical alarm ntawm "Striver" submersible, kev koom tes ntawm titanium alloy hauv cov cuab yeej sib sib zog nqus dej hiav txwv tau pub rov qab rau kev tshawb fawb thiab kev loj hlob.

III. Kev tsim kho ntawm Titanium Alloy Submarines

Cov tshiab titanium alloy composites yuav tsum tau ntxiv dag zog rau lub cev thiab corrosion kuj. Kev sib xyaw ua ke nrog lub suab nrov txo cov cuab yeej yuav txo cov suab nrov hauv qab dej ntawm titanium alloy submarines mus rau qib ntawm cov suab nrov hauv hiav txwv tom qab, paub qhov tseeb "stealth." Nyob rau tib lub sijhawm, kev sib koom ua ke ntawm kev txawj ntse txawj ntse thiab cov tshuab tsis siv neeg yuav ua rau titanium alloy submarines kom muaj kev tswj xyuas kev tswj xyuas thiab kev sib koom ua haujlwm muaj peev xwm, dhau los ua cov hauv paus tseem ceeb hauv kev sib ntaus sib tua hauv hiav txwv yav tom ntej.
