Lub luag haujlwm ntawm Titanium yog dab tsi?

Titanium yog cov hlau hloov pauv thiab tau suav tias yog cov hlau tsis tshua muaj rau qee lub sijhawm. Txij li thaum xyoo 1940s, titanium thiab nws cov tebchaw tau siv dav hauv dav hlau, foob pob ua ntxaij, missiles, satellites, spacecraft, naval ships, tub rog, kev kho mob thiab petrochemical teb. Vim tias titanium muaj cov ntsiab lus siab melting, siab hardness, muaj zog plasticity, me me ntom, corrosion kuj thiab lwm yam zoo; titanium zoo li hlau thiab muaj lub teeb grey lub teeb txhais lus. Lub zog ntawm titanium yog loj, lub zog tensile ntawm titanium alloy ncav cuag 180kg / mm3. Cov yam ntxwv ntawm titanium yog me me ntom (4.51g / cm3), siab hardness, siab melting point (1675 degree), siab purity titanium muaj plasticity zoo, tab sis thaum muaj impurities ua nkig thiab tawv. Nyob rau hauv chav tsev kub, titanium tsis cuam tshuam nrog chlorine, dilute sulfuric acid, dilute hydrochloric acid thiab nitric acid, tab sis yuav eroded los ntawm hydrofluoric acid, phosphoric acid thiab molten alkali. Titanium yog yooj yim yaj nyob rau hauv H2SO4, thiab cov khoom zoo tshaj plaws ntawm titanium yog nws muaj zog corrosion kuj rau seawater. Titanium ua rau li 0.42 feem pua ​​​​ntawm tag nrho qhov hnyav hauv ntiaj teb lub pob zeb, nyob rau qib xya hauv ntiaj teb hlau, nrog ntau dua 70 cov zaub mov muaj titanium. Tam sim no, titanium tau dav siv nyob rau hauv dav hlau, foob pob ua ntxaij, missiles, satellites, spacecraft, nkoj, tub rog kev lag luam, lub teeb kev lag luam, tshuaj lom neeg kev lag luam, textile kev lag luam, kev kho mob thiab petrochemical kev lag luam thiab lwm yam kev lag luam. Zoo heev titanium hmoov, yog ib tug zoo roj rau foob pob ua ntxaij; Qhov kev tiv thaiv corrosion ntawm titanium yog 15 npaug zog dua li cov hlau tsis tshua siv, thiab lub neej kev pabcuam yog ntau tshaj 10 npaug ntev dua li cov hlau tsis muaj steel. Kev siv titanium hauv kev phais kuj tseem nthuav heev. Tam sim no, cov pob txha phais tau teeb tsa nrog cov hlau tsis muaj steel, kev siv cov hlau tsis muaj steel muaj qhov tsis zoo, yog cov pob txha kho, tshem tawm cov ntawv hlau stainless dua, qhov no yog qhov mob heev. Txwv tsis pub, stainless hlau yuav ua rau tib neeg lub cev tsis zoo vim xeb. Hloov mus rau titanium "cov pob txha pob txha" yuav hloov tag nrho orthopedic thev naus laus zis. Ntawm lub taub hau ntawm kev puas tsuaj, siv titanium phaj nrog titanium screws, tom qab ob peb lub hlis, cov pob txha yuav loj hlob rov qab rau hauv titanium phaj qhov thiab ntsia hlau, cov leeg nqaij tshiab yog qhwv hauv daim ntawv titanium, titanium skeleton zoo li cov pob txha tiag tiag thiab lub cev ntawm kev txhawb nqa thiab kev txhawb nqa. cov nyhuv, yog li, titanium tau hailed li "hlau". Tam sim no nws tau pib siv rau hauv lub hauv caug sib koom tes, lub xub pwg sib koom ua ke, tav kev sib koom ua ke, cranium, lub plawv dhia dhia, pob txha fixation clip thiab lwm yam. Hauv kev lag luam steelmaking, me me ntawm titanium yog ib qho zoo deoxidation, nitrogen thiab sulfur tshem tawm tus neeg sawv cev. Dioxy titanium yog cov xim dawb dawb hu ua titanium dioxide. Titanium dioxide muaj cov khoom zais ntawm cov hlau lead dawb thiab durability ntawm zinc dawb. Nws yog ib qho ntawm cov tshuaj dawb tshaj plaws hauv ntiaj teb, thiab titanium dioxide tsis muaj tshuaj lom. Ntau pua txhiab tons ntawm titanium dioxide tam sim no siv los ua cov xim txhua xyoo. Vim nws cov ntsiab lus melting siab, titanium dioxide feem ntau yog siv los ua cov iav refractory, glaze, enamel, av nplaum, siab kub resistant sim nkoj, thiab lwm yam. Titanium tetrachloride muab tawm ntau cov pa luam yeeb dawb hauv huab cua ntub. Vim hais tias ntawm cov cuab yeej no, nws yog feem ntau siv nyob rau hauv cov tub rog ua ib tug dag smog neeg sawv cev. Tshwj xeeb tshaj yog nyob rau hauv dej hiav txwv, dej vapor, titanium tetrachloride, pa luam yeeb zoo li lub phab ntsa dawb, thaiv cov yeeb ncuab txoj kab ntawm qhov pom. Barium titanate crystals yog dav siv nyob rau hauv ultrasonic instruments thiab underwater detectors. Qhov no yog vim hais tias thaum lub compression chop hloov cov duab, nws yuav tsim tam sim no; Nws hloov cov duab thaum siv hluav taws xob. Thaum barium titanate muab tso rau hauv ultrasonic yoj, nws yuav tsim tam sim no nyob rau hauv siab. Lub zog ntawm ultrasonic yoj tuaj yeem ntsuas los ntawm qhov tam sim no tsim los ntawm nws. Hloov chaw, hluav taws xob ntau zaus dhau los ntawm nws los tsim ultrasonic tsis. Nyob rau hauv cov khoom siv tes ua thiab cov khoom siv niaj hnub dai kom zoo nkauj nrog kub, lawv tsis ruaj khov vim lawv tsis tshua muaj zog, yooj yim rau puncture thiab hnav. Thaum ib txheej ntawm titanium nitride plated rau saum npoo ntawm cov ntaub ntawv no, cov tsos zoo li yuav luag zoo tib yam rau cov txheej kub, tab sis nws muaj peev xwm tiv taus hnav dua li kub thiab tawv alloy, thiab txheej yog hu ua "tsis txhob hnav." Organic titanium polymer, tuaj yeem siv ua surfactant, dispersant, dej resistant tus neeg saib xyuas los yog xeb inhibitor. Tib neeg tam sim no siv plaub series ntawm hydrogen cia hauv cov hlau, titanium yog ib hom, kuj yog ib yam pheej yig dua, tab sis tam sim no tsis tau pom ib tug zoo tagnrho tib neeg "hydrogen cia hlau", ib zaug qhov teeb meem daws, tib neeg siv tau. hydrogen li roj. "titanium aircraft" uas tuaj yeem txo lub cev hnyav 5 tons, ntau tshaj li 100 tus neeg caij tsheb. Hauv cov tshuab dav hlau tshiab, titanium alloy twb tso nyiaj rau 18-25 feem pua ​​​​ntawm qhov hnyav ntawm tag nrho lub cav. Hauv qhov tseeb supersonic aircraft, titanium suav txog yuav luag 95 feem pua ​​​​ntawm tag nrho qhov hnyav ntawm tag nrho cov qauv, yog li nws yuav nyuaj rau tsim lub dav hlau supersonic tam sim no yam tsis muaj titanium. Submarines ua los ntawm titanium tsis yog tsuas yog ruaj dua li cov hlau, tab sis kuj tuaj yeem dhia mus rau qhov tob dua. Titanium submarines tuaj yeem dhia dej mus txog 4,500 meters, uas yog qhov txwv tsis pub nkag mus rau steel submarines. Titanium yog siv los ua cov nkoj thiab nkoj, uas tsis tas yuav tsum tau pleev xim thiab yuav tsis xeb tom qab xyoo ntawm kev caij nkoj hauv hiav txwv. Txij li thaum titanium tsis yog ferromagnet thiab tsis tuaj yeem kuaj pom los ntawm cov mines sib nqus, qhov no yog qhov tseem ceeb ntawm tub rog. Yog tsis muaj titanium tshav kub-resistant steel, lub neej ntev ntawm phom thiab tshuab phom siv niaj hnub no tsuas yog thawj zaug 4.5 vib nas this. Siv lub zog nqus cua los ntawm titanium thiab zirconium, huab cua tuaj yeem raug tshem tawm, tsim lub tshuab nqus tsev. Lub tshuab nqus tsev twj tso kua mis, ua los ntawm titanium thiab zirconium, tso cua mus rau ib feem ntawm ib billion. Ti-Nb alloy yog cov khoom siv zoo tshaj plaws. Tsinghua University siv lub hauv paus ntsiab lus ntawm kev cuam tshuam kho qhov muag thiab kev kho titanium ion nitride los tsim cov duab meej, txheej roob ink paintings. Ntawm ob feem ntau cov stainless hlau siv niaj hnub no, Inconel 18-8-1 (18 feem pua ​​​​chromium, 8 feem pua ​​​​nickel, 1 feem pua ​​​​titanium) yog feem ntau siv hauv kev lag luam. Titanium carbide (TiC) zoo ib yam li hlau carbide, nrog ib tug hlau luster. Tab sis nws muaj cov ntsiab lus melting ntau dua thiab hardness ntau dua li cov hlau carbide. Yog li ntawd, nws muaj ib tug siv tau. Cov zaub mov khaws cia hauv cov hlab ntsha titanium muaj xim ntev, tsw thiab saj. Titanium cookware yog lub teeb yuag, thiab yuav tsis xeb, kev noj qab haus huv tshaj plaws. Ua los ntawm titanium alloy, lub nkoj siab tuaj yeem tiv taus txog li 2500 cua. Ib qho alloy ntawm titanium thiab npib tsib xee, hu ua "nco alloy", yog ua los ntawm kev txiav txim siab ua ntej, uas yog tom qab ntawd zoo li tus thiab, yog tias deformed los ntawm sab nraud quab yuam, tuaj yeem rov qab los rau nws qhov qub qub nrog kub me ntsis. Cov hlau no tau siv hauv ntau qhov chaw. Piv txwv li, lub kav hlau txais xov siv nyob rau hauv lub Apollo spacecraft, piv txwv li, yog lub cim xeeb alloy; Lub Tsev Kho Mob Ninth Tib Neeg Koom Tes rau Shanghai Thawj Tsev Kawm Ntawv Kho Mob tau siv lub cim xeeb alloy hauv cov poj niam kev ua kom tsis muaj menyuam; Tsis tas li ntawd, nws tseem tuaj yeem siv rau hauv kev ntsuas, khoom siv hluav taws xob thiab lwm yam haujlwm. Tam sim no, qhov teeb meem loj tshaj plaws rau kev siv titanium thoob plaws yog tias nws nyuaj rau smelt. Vim hais tias lub melting point ntawm titanium yog siab heev, smelting titanium yuav tsum tau nqa tawm nyob rau hauv lub kub kub, thiab cov tshuaj ntawm titanium ua hauj lwm nyob rau hauv kub kub, yog li smelting yuav tsum tau nqa tawm nyob rau hauv kev tiv thaiv ntawm inert gas, tab sis kuj ua. tsis siv cov khoom siv oxygen, uas ua rau muaj kev xav tau siab ntawm cov khoom siv smelting thiab txheej txheem. Kwv yees li 70 feem pua ​​​​ntawm titanium smelting yog siv rau hauv kev tsim cov dav hlau, missiles, spaceships, thiab satellites. Titanium muaj kev cia siab rau yav tom ntej, yog li nws tau txais lub npe ntawm "hlau ntawm 21st Century".
