Titanium yog corrosion-resistant, yog li nws yog feem ntau siv nyob rau hauv kev lag luam tshuaj. Yav dhau los, cov khoom uas muaj kub nitric acid nyob rau hauv cov tshuaj reactors yog ua los ntawm stainless hlau. Stainless hlau tseem ntshai ntawm cov muaj zog corrosive tus neeg sawv cev - kub nitric acid. Txhua rau lub hlis, tag nrho cov khoom no yuav tsum tau hloov. Siv titanium los tsim cov khoom siv no, txawm tias kim dua li cov khoom siv hlau tsis muaj steel, tuaj yeem siv tsis tu ncua rau tsib xyoos, ua rau nws raug nqi ntau dua los suav.
Titanium thiab nws cov alloys tau siv dav hauv kev lag luam aviation thiab hu ua "qhov chaw hlau"; Tsis tas li ntawd, nws tau siv dav hauv kev lag luam shipbuilding, tshuaj lom neeg kev lag luam, kev tsim khoom ntawm cov khoom siv hluav taws xob, cov khoom siv sib txuas lus, hard alloys, thiab lwm yam. Ntshiab titanium yog cov hlau dawb uas muaj ntau yam zoo heev. Titanium muaj qhov ntom ntom 43% qis dua hlau thiab me ntsis siab dua li lub teeb hlau muaj npe magnesium. Titanium muaj lub zog siab, thiab lub zog tensile ntawm ntshiab titanium tuaj yeem ncav cuag 180kg / mm2, uas zoo ib yam li cov hlau, ob npaug ntawm txhuas, thiab tsib npaug ntawm magnesium. Titanium yog kub-resistant, nrog ib tug melting point ntawm 1942K, ze li ntawm 1000K siab tshaj kub thiab ze li ntawm 500K siab tshaj hlau. Qee cov hlau muaj lub zog ntau dua li cov titanium alloys, tab sis lub zog tshwj xeeb (qhov sib piv ntawm lub zog tensile rau qhov ntom ntom) ntawm titanium alloys tshaj li cov hlau zoo. Titanium alloy muaj cov cua kub zoo, tsis tshua muaj kub toughness, thiab tawg toughness, yog li nws yog feem ntau siv los ua aircraft cav qhov chaw thiab foob pob ua ntxaij thiab missile structural Cheebtsam. Titanium alloys kuj tseem siv tau los ua roj thiab oxidant cia tank, nrog rau cov thawv ntim siab. Titanium alloy tau siv los tsim cov phom tsis siv neeg, tshuaj khib nyiab, thiab cov phom phom tsis siv neeg. Hauv kev lag luam roj av, nws tsuas yog siv rau ntau lub thawv, reactors, kub exchangers, distillation towers, pipelines, twj, thiab li qub. Titanium tuaj yeem siv los ua electrodes, condensers hauv cov chaw tsim hluav taws xob, thiab cov khoom siv hluav taws xob ib puag ncig. Titanium nickel zoo nco alloys tau siv dav hauv cov twj thiab ntsuas. Hauv tshuaj, titanium tuaj yeem siv los ua cov pob txha pob txha thiab ntau yam cuab yeej. Titanium tseem yog deoxidizer hauv steelmaking thiab ib feem ntawm stainless hlau thiab hlau alloy. Titanium dioxide yog cov khoom siv zoo rau cov xim thiab xim. Titanium carbide thiab titanium hydride yog hom tshiab ntawm cov ntaub ntawv nyuaj. Titanium nitride muaj xim zoo ib yam li kub thiab siv dav hauv kev kho kom zoo nkauj.
Titanium belongs rau cov hlau uas muaj cov tshuaj lom neeg muaj zog. Thaum tshav kub kub, nws tuaj yeem cuam tshuam nrog cov khoom tsis yog xim hlau xws li O2, N2, H2, S, thiab halogens. Txawm li cas los xij, nyob rau hauv chav tsev kub, ib tug nyias thiab ntom oxide tiv thaiv zaj duab xis yog yooj yim tsim nyob rau saum npoo ntawm titanium, uas muaj peev xwm tiv taus cov teebmeem ntawm cov acids muaj zog thiab txawm aqua regia, muaj zog corrosion kuj. Yog li ntawd, cov hlau dav dav dhau los ua riddled nrog qhov nyob rau hauv cov kev daws teeb meem ntawm acid, alkali, thiab ntsev, thaum titanium tseem unscathed.
Cov kua titanium tuaj yeem yaj yuav luag txhua cov hlau, yog li nws tuaj yeem tsim cov alloys nrog ntau yam hlau. Titanium hlau ua los ntawm kev ntxiv titanium rau hlau yog tawv thiab elastic. Titanium tuaj yeem yaj rau hauv cov alloys nrog lwm cov ntsiab lus xws li hlau, txhuas, vanadium, los yog molybdenum los tsim lub teeb pom kev zoo, uas muaj ntau yam kev siv hauv ntau yam, suav nrog aerospace ( dav hlau cav, missiles, thiab spacecraft), tub rog , cov txheej txheem kev lag luam (tshuaj lom neeg thiab roj av, seawater desalination, thiab papermaking), tsheb, khoom ua liaj ua teb thiab khoom noj khoom haus, tshuaj (prosthetics, orthopedic transplants, khoom siv kho hniav thiab muab tub lim), cov tais diav hauv chav ua noj, khoom siv ncaws pob, hniav nyiaj hniav kub, thiab xov tooj ntawm tes, thiab lwm yam. ntawm. Titanium alloy muaj lub zog siab thiab siv dav hauv kev tsim cov khoom siv rau cov tub rog supersonic aircraft, compression Cheebtsam rau lub dav hlau xyaw, cov khoom siv rau lub dav hlau thav ntawv, casings, phab ntsa hluav taws, thiab rivets; Cov yam ntxwv ntawm cov khoom siv thauj huab cua; Armor daim hlau rau cov chaw tub rog thiab cov nkoj ua rog, nrog rau cov hniav rau cov kiv cua. Hauv kev lag luam hauv kev lag luam, titanium thiab nws cov alloys tuaj yeem siv los tsim cov hlau xaim mesh thiab ntau yam tshuab rau ntau yam twj, li qub, pom, thiab cov khoom siv evaporation. Powdered titanium tuaj yeem siv los ua deoxidizer hauv kev tsim cov raj hluav taws xob. Feem ntau yog siv rau kev tsim cov chaw shuttles, foob pob ua ntxaij foob pob hluav taws, submarines, cov khoom siv tshuaj, cov khoom siv kho mob, cov pob qij txha, thiab lwm yam, thiab tseem tsim cov titanium dioxide.
Nws tuaj yeem siv los ua cov hlab ntsha, condensers, fermentation tanks, thiab coolers.
Cov dav hlau ua los ntawm titanium alloy nqa ntau tshaj 100 tus neeg caij tsheb ntau dua li cov dav hlau ua los ntawm lwm cov hlau uas hnyav sib npaug. Lub submarine ua los ntawm nws muaj peev xwm tiv tau ob qho tib si seawater corrosion thiab sib sib zog nqus siab, thiab nws qhov tob tob yog 80% siab dua li ntawm stainless hlau submarines. Nyob rau tib lub sijhawm, titanium tsis yog hlau nplaum thiab yuav tsis raug kuaj pom los ntawm cov mines, uas muaj kev tiv thaiv zoo.
Vim nws biocompatibility, titanium tuaj yeem tiv thaiv corrosion ntawm secretions hauv tib neeg lub cev thiab tsis muaj tshuaj lom, ua rau nws haum rau txhua txoj kev ua kom tsis muaj menyuam. Yog li ntawd, nws yog dav siv nyob rau hauv kev tsim cov khoom siv kho mob, pob qij txha pob qij txha, pob qij txha, pob qij txha, pob qij txha, pob txha taub hau, lub plawv dhia, thiab cov pob txha kho cov pob txha. Thaum cov leeg nqaij tshiab nyob ib puag ncig cov pob txha titanium no, lawv pib tswj hwm tib neeg kev ua haujlwm.
Titanium yog dav faib nyob rau hauv tib neeg lub cev, thiab nws cov ntsiab lus nyob rau hauv tib neeg lub cev yog tsis ntau tshaj 15mg ib 70kg lub cev hnyav. Nws cov nyhuv tseem tsis meej. Tab sis titanium tau raug pov thawj los txhawb phagocytic hlwb thiab txhim khu kev tiv thaiv kab mob.
