Dab tsi yog titanium phaj siv rau?

1, Titanium phaj nyob rau hauv thickness ntawm 18 hli, 20 hli, mus txog 50 hli.

 

Raws li silvery-dawb hloov hlau, titanium plays lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub vim nws cov khoom zoo tshaj. Titanium daim hlau, raws li ib qho ntawm cov ntaub ntawv tseem ceeb ntawm cov ntaub ntawv titanium, yog siv dav hauv aerospace, kev kho mob, tshuaj, thiab kev lag luam. Kab lus no yuav muab cov ntsiab lus dav dav ntawm cov yam ntxwv, kev faib tawm, kev tsim khoom, kev siv, thiab kev txhim kho yav tom ntej ntawm titanium daim hlau, txhawm rau pab cov neeg nyeem kom nkag siab zoo txog cov khoom tseem ceeb no.

Titanium muaj qhov siab melting point ntawm 1668℃thiab qis coefficient ntawm thermal expansion, uas tso cai rau nws kom ruaj khov kev ua tau zoo txawm nyob rau hauv qhov kub thiab txias. Tsis tas li ntawd, titanium muaj kev ua haujlwm zoo heev, ua rau nws ua tiav rau ntau yam duab los ntawm kev sib tsoo, dov, vuam, thiab lwm yam txheej txheem. Cov khoom no sib sau ua ke muab cov ntawv titanium muaj txiaj ntsig zoo sib tw, ua rau lawv yog cov khoom siv tseem ceeb hauv kev lag luam niaj hnub no.

2. Kev faib tawm ntawm titanium phaj

 

Titanium daim hlau tuaj yeem muab faib ua ntau hom raws li cov qauv sib txawv. Raws li cov tshuaj muaj pes tsawg leeg, titanium daim hlau feem ntau muab faib ua ob pawg: ntshiab titanium daim hlau thiab titanium alloy daim hlau. Ntshiab titanium daim hlau tau muab faib ua cov qib xws li TA1, TA2, thiab TA3, nrog kev purity txo thiab lub zog nce ntxiv. Ntshiab titanium daim hlau yog dav siv nyob rau hauv cov khoom siv tshuaj thiab lub tsev kho kom zoo nkauj vim lawv zoo heev plasticity thiab weldability. Titanium alloy daim hlau yog tsim los ntawm kev ntxiv cov ntsiab lus xws li txhuas, vanadium, thiab molybdenum rau cov ntshiab titanium los txhim kho lawv cov khoom. Cov qib muaj xws li TC4 (Ti-6Al-4V) thiab TC11 (Ti-6.5Al-3.5Mo-1.5Zr-0.3Si). TC4 titanium phaj, raws li ib qho ntawm feem ntau siv titanium alloys, sib txuas lub zog siab, zoo heev kub tsis kam, thiab corrosion kuj, thiab yog dav siv nyob rau hauv aerospace thiab kev kho mob teb. Nws lub zog tensile tshaj 895 MPa, thiab nws cov kev khiav hauj lwm kub tuaj yeem ncav cuag 400 degree.

Raws li qhov sib txawv ntawm cov txheej txheem tsim khoom, titanium daim hlau tuaj yeem muab faib ua ob pawg: kub- dov daim hlau thiab txias- dov daim hlau. Kub- cov phaj dov yog dov saum cov khoom siv qhov kub thiab txias, thiab lawv cov tuab feem ntau yog ntau dua 3 hli, muaj zog thiab tawv. Txias- cov phaj dov yog dov nyob rau hauv chav tsev kub, ua rau ib tug nyias thickness (feem ntau tsawg dua 3 hli), thiab muab superior nto tiav thiab qhov tseeb. Tsis tas li ntawd, muaj titanium composite daim hlau. Cov phaj no yog tsim los ntawm kev sib txuas cov titanium daim hlau nrog lwm cov hlau xws li hlau thiab txhuas los ntawm kev sib tsoo tawg lossis dov cov txheej txheem. Lawv khaws cov kev tiv thaiv corrosion ntawm titanium thaum koom nrog lub zog siab ntawm cov khoom siv hauv paus, thiab feem ntau yog siv rau hauv cov khoom siv tshuaj lom neeg thiab marine engineering teb.

3.Titanium phaj raug txheej txheem

 

Titanium Phaj Ntau Lawm Txheej Txheem Cov txheej txheem ntawm titanium daim hlau yog qhov nyuaj, suav nrog ntau cov kauj ruam nrog rau kev npaj daim txhuam cev titanium, smelting, forging, dov, thiab tom qab ua tiav. Ua ntej, daim txhuam cev titanium yog tsim los ntawm titanium ore siv cov magnesiothermal txo txoj kev los yog electrolysis. Tom qab ntawd, daim txhuam cev titanium yog crushed, graded, thiab tov nrog alloying ntsiab, ua ntej smelted rau hauv titanium ingots nyob rau hauv lub tshuab nqus tsev arc rauv los yog txias hearth cub.

Titanium ingots tau txais ntau yam txheej txheem forging los tsim cov slabs. Cov slabs no ces ua tiav rau hauv titanium daim hlau ntawm lub hom phiaj thickness siv kub los yog txias dov. Kub dov yog feem ntau ua rau saum toj ntawm -theem transformation kub ntawm titanium kom txo deformation kuj; txias dov tshwj xeeb yog siv los ua cov phaj nyias thiab siab -cov ntawv txheeb. Thaum lub sij hawm dov, kub thiab deformation yuav tsum raug tswj kom tsis txhob muaj qhov tsis xws luag xws li cov kab nrib pleb lossis tsis sib xws.

Tom qab tau dov rau hauv cov duab, titanium daim hlau yuav tsum tau ua ntau yam kev kho mob tom qab, nrog rau kev sib tsoo, ncaj, thiab pickling. Annealing zoo tshem tawm cov kev ntxhov siab thiab ua kom zoo dua cov khoom siv microstructure thiab cov khoom; pickling aims tshem tawm oxide txheej txheej thiab txhim kho qhov zoo ntawm lub phaj. Rau qee qhov tshwj xeeb daim ntawv thov, titanium daim hlau kuj yuav xav tau kev kho saum npoo (xws li anodizing lossis txau) txhawm rau txhim kho lawv cov kev tiv thaiv corrosion los yog txhim kho lawv qhov muag pom.

 

Titanium thiab nws cov alloys muaj kev siv dav hauv ntau lub teb vim lawv cov khoom tshwj xeeb. Nov yog qee qhov kev siv tseem ceeb ntawm titanium:

Titanium thiab titanium alloys nthuav tawm tshwj xeeb toughness, nrog ib tug hardness piv rau hlau, uas ua rau lub zog zoo heev mechanical zog piv rau lwm cov ntaub ntawv alloy, ua rau lawv arguably qhov zoo tagnrho siab - cov ntaub ntawv muaj zog. Titanium kuj muaj qhov ntom ntom, tsuas yog ib nrab ntawm cov hlau uas yog cov hlau hnyav. Hloov cov hlau alloy feem ntau siv hauv cov qauv dav hlau nrog titanium alloys tuaj yeem txo qhov hnyav li ntawm 40%.

 

 

 

Titanium muaj biocompatibility zoo heev thiab yuav tsis ua rau tsis lees paub thaum nyob rau hauv kev sib cuag nrog tib neeg lub cev. Raws li cov cuab yeej no, titanium yog siv dav hauv kev tsim khoom ntawm ntau yam khoom siv kho mob, xws li cog thiab kho hniav cov ntaub ntawv.

 

 

Titanium ua tau zoo nyob rau hauv dej hiav txwv ib puag ncig thiab tsis corrodes. Vim li no, titanium feem ntau yog siv los tsim cov chaw marine thiab cov khoom hauv nkoj.

 

 

Titanium muaj ntau yam xim. Tom qab oxidation kev kho mob, nws nto tuaj yeem pom ntau yam xim, uas yog ib qho ntawm cov laj thawj tseem ceeb uas vim li cas titanium tau nyiam nyob rau hauv cov hniav nyiaj hniav kub thiab zam kev lag luam hauv xyoo tas los no. Tib neeg tau pib siv titanium los ua cov kauj-toog npab, caj dab thiab lwm yam hniav nyiaj hniav kub, thiab txawm tias lub xov tooj ntawm tes.

 

 

 

Nrog nws zoo heev corrosion kuj thiab biocompatibility, titanium ua tau zoo nyob rau hauv ib puag ncig tiv thaiv daim ntaub ntawv xws li dej khib nyiab thiab huab cua purification.

 

 

 

Titanium tuaj yeem siv los ua cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, nrog rau cov khoom siv hluav taws xob ib puag ncig.

 

 

 

Titanium tuaj yeem siv los ua deoxidizer hauv cov txheej txheem steelmaking, thiab nws kuj yog ib qho tseem ceeb ntawm stainless hlau thiab hlau alloy.

 

 

Titanium carbide thiab titanium hydride yog cov khoom siv cemented carbide tshiab.

 

 

Titanium nitride yog ze rau cov xim kub thiab muaj ntau yam kev siv hauv kev kho kom zoo nkauj.

 

Hauv kev xaus,titanium muaj ntau yam kev siv, npog aerospace, khoom siv txhua hnub, kev kho mob thiab kev noj qab haus huv, thiab ib puag ncig engineering, ua kom pom tseeb nws tus nqi tshwj xeeb thiab cov txiaj ntsig tseem ceeb.

Titanium, silvery -hloov pauv hlau, yog siv nyob rau hauv niaj hnub kev lag luam rau 18mm, 20mm, thiab txawm 50mm tuab titanium daim hlau vim nws superior zog. Titanium daim hlau, raws li daim ntawv tseem ceeb ntawm cov khoom siv titanium, muaj kev siv dav hauv aerospace, kev kho mob, tshuaj, thiab kev tsim kho. Kab lus no yuav piav qhia txog cov yam ntxwv, kev faib tawm, cov txheej txheem tsim khoom, thaj chaw thov, thiab kev txhim kho yav tom ntej ntawm titanium daim hlau, pab cov neeg nyeem kom paub meej thiab hauv - nkag siab tob txog cov ntaub ntawv tseem ceeb no.
