Titanium yog cov hlau uas muaj cov khoom siv tshuaj lom neeg. Thaum tshav kub kub, nws tuaj yeem cuam tshuam nrog cov hlau tsis xws li O2, N2, H2, s thiab halogen. Txawm li cas los xij, ntawm qhov kub thiab txias, ib qho yooj yim thiab ntom oxide tiv thaiv zaj duab xis yog yooj yim tsim rau saum npoo ntawm titanium, uas tuaj yeem tiv taus qhov kev txiav txim ntawm cov kua qaub muaj zog thiab txawm tias aqua regia, qhia muaj zog corrosion kuj. Yog li ntawd, cov hlau dav dav dhau los ua riddled nrog qhov hauv cov kua qaub, alkali thiab ntsev, thaum titanium muaj kev nyab xeeb.
Cov kua titanium tuaj yeem yaj yuav luag txhua cov hlau, yog li nws tuaj yeem tsim cov alloys nrog ntau yam hlau. Titanium steel ua los ntawm kev ntxiv titanium rau hlau yog tawv thiab elastic. Cr, Fe thiab cov zoo li tsim cov sib txuas sib txuas lossis cov sib txuas sib txuas.
Titanium yog ib qho kev hloov pauv hlau, uas tau suav tias yog cov hlau tsis tshua muaj rau lub sijhawm ntev dhau los.
Txij li thaum xyoo 1940, titanium thiab nws cov tebchaw tau siv dav hauv dav hlau, foob pob hluav taws, foob pob hluav taws, khoom siv satellites, dav hlau, nkoj nkoj, kev lag luam tub rog, kev kho mob, petrochemical thiab lwm yam kev lag luam; Vim tias titanium muaj qhov zoo ntawm qhov siab melting point, siab hardness, muaj zog plasticity, tsawg ntom thiab corrosion kuj; Titanium zoo li hlau, nrog nyiaj grey teeb.
Lub zog tensile ntawm titanium alloy yog 180kg / mm3. Titanium yog tus cwj pwm los ntawm qhov ntom ntom (4.51g / cm3), siab hardness thiab siab melting point (1675 degree). High purity titanium muaj cov yas zoo, tab sis ua nkig thiab tawv thaum muaj impurities. Nyob rau hauv chav tsev kub, titanium tsis hnov mob nrog chlorine, dilute sulfuric acid, dilute hydrochloric acid thiab nitric acid, tab sis tuaj yeem eroded los ntawm hydrofluoric acid, phosphoric acid thiab molten alkali.
Titanium yog yooj yim yaj hauv H2SO4. Qhov zoo tshaj plaws kev ua tau zoo ntawm titanium yog nws muaj zog corrosion kuj rau dej hiav txwv. Titanium suav txog kwv yees li 0.42% ntawm tag nrho qhov hnyav hauv lub ntiaj teb pob zeb, nyob rau qib xya hauv ntiaj teb hlau, thiab muaj ntau dua 70 hom minerals uas muaj titanium. Tam sim no, kev siv cov titanium tau tsim sai heev, thiab nws tau siv dav hauv dav hlau, foob pob hluav taws, foob pob hluav taws, cov khoom siv hluav taws xob, lub nkoj, nkoj, kev ua rog, kev lag luam tub rog, kev lag luam teeb, kev lag luam tshuaj, textile, kev kho mob, petrochemical thiab lwm yam kev lag luam.
Cov hmoov zoo heev titanium yog cov roj zoo rau Rockets; Kev tiv thaiv corrosion ntawm titanium yog 15 npaug zog dua li ntawm cov hlau tsis zoo, thiab nws lub neej kev pab cuam yog ntau tshaj 10 npaug ntev dua li ntawm cov hlau tsis muaj steel. Daim ntawv thov ntawm titanium hauv kev phais thiab kev kho mob kuj yog qhov txaus nyiam heev. Tam sim no, stainless hlau yog siv rau kev phais pob txha. Muaj qhov tsis zoo ntawm kev siv cov hlau tsis muaj steel, uas yog, tom qab cov pob txha zoo lawm, cov ntawv hlau stainless yuav tsum tau muab tshem tawm dua, uas yog qhov mob heev. Txwv tsis pub, stainless hlau yuav ua rau tib neeg lub cev raug mob vim xeb. Yog tias siv "cov pob txha pob txha" ua los ntawm titanium, cov tshuab orthopedic yuav hloov tag nrho. Titanium raug qhuas tias yog "cov hlau lom". Tam sim no nws tau raug siv rau hauv caug sib koom tes, lub xub pwg sib koom ua ke, tav kev sib koom tes, pob txha taub hau, lub plawv dhia, pob txha fixation clamp thiab lwm yam.
Hauv kev lag luam steelmaking, me me ntawm titanium yog ib qho zoo deoxidizer, nitrogen thiab sulfur tshem tawm. Titanium dioxide yog ib qho tseem ceeb xim xim hu ua titanium dioxide. Titanium dawb yog ib qho ntawm cov khoom siv dawb tshaj plaws hauv ntiaj teb, thiab nws tsis muaj tshuaj lom. Tam sim no muaj ntau pua txhiab tons ntawm titanium dioxide siv los ua xim txhua xyoo.
Titanium yog ib qho ntawm plaub series ntawm hydrogen cia hlau tam sim no siv los ntawm noob neej, thiab nws kuj yog ib qho pheej yig. Txawm li cas los xij, tam sim no, noob neej tsis tau pom qhov zoo tshaj plaws "hydrogen cia hlau". Thaum daws qhov teeb meem no, tib neeg tuaj yeem siv hydrogen ua roj.
"titanium aircraft" tuaj yeem txo lub cev hnyav ntawm 5 tons thiab nqa ntau tshaj 100 tus neeg caij tsheb. Hauv lub tshuab dav hlau tshiab, titanium alloy nyiaj rau 18-25% ntawm tag nrho lub cav hnyav; Nyob rau hauv qhov tseeb supersonic aircraft, kev siv titanium account rau yuav luag 95% ntawm tag nrho cov hnyav ntawm tag nrho lub cev qauv. Yog li ntawd, nws yog qhov nyuaj los tsim lub dav hlau supersonic tam sim no tsis muaj titanium alloy.
Submarines ua los ntawm titanium tsis yog tsuas yog ruaj dua li cov hlau submarines, tab sis kuj tuaj yeem dhia tob dua. Titanium submarines tuaj yeem dhia hauv qab 4500 meters, uas yog qhov txwv uas cov hlau submarines tsis tuaj yeem hla. Cov nkoj thiab nkoj ua los ntawm titanium tsis tas yuav tsum tau pleev xim, thiab lawv yuav tsis xeb tom qab caij nkoj hauv hiav txwv tau ntau xyoo. Txij li thaum titanium tsis yog cov khoom siv ferromagnetic thiab yuav tsis pom los ntawm cov mines sib nqus, qhov no tseem ceeb tshwj xeeb hauv kev ua tub rog. Yog tsis muaj cov cua kub-resistant steel ua los ntawm titanium, lub neej kev pab cuam ntawm cov pa riam phom thiab tshuab phom siv tam sim no tsuas yog thawj 4.5 vib nas this.
Siv lub zog nqus ntawm titanium thiab zirconium rau huab cua, huab cua tuaj yeem raug tshem tawm los tsim lub tshuab nqus tsev. Lub tshuab nqus tsev twj tso kua mis ua los ntawm titanium zirconium alloy tuaj yeem tso cua kom tsuas yog ib billionth.
Lub alloy muaj li ntawm titanium thiab npib tsib xee hu ua "memory alloy". Cov alloy no yog tsim los rau hauv cov duab predetermined, thiab tom qab teeb tsa kev kho mob, yog tias nws yog deformed los ntawm sab nraud quab yuam, nws tuaj yeem rov qab los rau nws qhov zoo li qub, tsuav nws yog me ntsis rhuab. Cov hlau no tau siv rau hauv ntau qhov chaw. Piv txwv li, lub kav hlau txais xov siv nyob rau hauv lub Apollo spacecraft 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 no hauv kev ua haujlwm ntawm poj niam kom tsis muaj menyuam; Tsis tas li ntawd, nws tseem tuaj yeem siv rau hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
