Lub versatility ntawm titanium raws li ib yam khoom yog kab tias feem ntau tshwm sim nyob rau hauv nws daim ntawv hlau. Los ntawm cov mesh mesh siv nyob rau hauv lub pob txha taub hau reconstruction mus rau hnyav - lub luag hauj lwm springs nyob rau hauv siab - kev ua tau zoo sib tw cav, Titanium hlau yog ib qho tseem ceeb tivthaiv nyob rau hauv ib tug spectrum ntawm xav tau kev lag luam. Txawm li cas los xij, rau cov tsis tau pib, tag nrho cov titanium yuav zoo tib yam. Hauv kev muaj tiag, qhov sib txawv ntawm qhov sib txawv ntawm cov qib yog qhov tob, hais txhua yam los ntawm ntau npaum li cas cov hlau tuaj yeem khoov mus rau ntau npaum li cas nws tuaj yeem tiv taus ua ntej snapping.
Kev nkag siab txog cov nuances ntawm Qib 1, Qib 2, thiab Qib 5 yog qhov tseem ceeb rau txhua tus kws ua haujlwm lossis tus neeg ua haujlwm yuav khoom. Xaiv qhov tsis ncaj ncees lawm qib ntawm Titanium Hlau tuaj yeem ua rau muaj kev puas tsuaj rau cov khoom siv tsis zoo lossis cov nqi tsim nyog. Phau ntawv qhia no muab qhov tob tob rau hauv cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov kev siv zoo tshaj plaws ntawm peb qib tseem ceeb.
1. Tsev Neeg Pure Commercially (CP): Qib 1 thiab Qib 2
Kev lag luam Pure (CP) titanium yog unalloyed. Nws muaj feem ntau ntawm cov titanium ntshiab nrog cov lej ntawm cov khoom sib txuas xws li hlau, carbon, hydrogen, thiab - tseem ceeb tshaj -oxygen. Cov ntsiab lus oxygen yog "dial" uas cov neeg tsim khoom tig los kho lub zog thiab ductility.
Qib 1: Peak of Ductility
Qib 1 yog qhov softest thiab feem ntau ductile ntawm tag nrho cov qib titanium. Nws muaj cov ntsiab lus oxygen qis tshaj plaws, uas ua rau cov khoom siv yooj yim heev.
Yam ntxwv: Nws coj yuav luag zoo li cov hlau muaj nuj nqis nyob rau hauv cov nqe lus ntawm malleability. Nws muaj qhov txias txias zoo heev - tsim cov khoom thiab tuaj yeem rub mus rau hauv Titanium Hlau zoo heev yam tsis tas yuav nkig dhau.
Corrosion Resistance: Zoo li tag nrho cov titanium, nws tsim cov txheej txheem oxide tiv thaiv, tab sis Qib 1 tshwj xeeb tshaj yog nyiam nyob rau hauv ib puag ncig uas cov hlau yuav tsum tau zoo li tus geometries nyuaj thaum tswj qhov siab tshaj plaws tiv thaiv tshuaj tua kab mob.
Cov ntawv thov zoo tshaj plaws: Koj yuav pom Qib 1 Titanium Hlau nyob rau hauv cov ntawv thov kev tsim vaj tsev, tshwj xeeb cov txheej txheem tshuaj mesh, thiab ua cov khoom siv rau cov khoom tawg.
Qib 2: Kev Ua Haujlwm Ua Haujlwm
Qib 2 yog dav suav hais tias yog "tus qauv" rau cov ntawv thov kev lag luam. Nws muaj cov pa oxygen ntau dua thiab cov ntsiab lus hlau me dua li Qib 1, uas muab kev txhawb nqa tseem ceeb hauv lub zog thaum tswj kev weldability zoo.
Qhov Ntsuas: Yog Qib 1 yog hais txog "softness," Qib 2 yog hais txog "sib npaug." Nws muaj lub zog tawm los ntau dua li Qib 1 tab sis tseem muaj cov kab mob txaus rau feem ntau cov qauv kev ua haujlwm.
Versatility: Feem ntau tawm -- txee Titanium Hlau siv rau kev tsim khoom dav dav, fasteners, thiab cov qauv kev txhawb nqa yog Qib 2. Nws yog tus nqi tshaj plaws -kev daws teeb meem zoo rau cov cheeb tsam uas xav tau kev tiv thaiv corrosion siab tab sis lub cev muaj zog.
Kev siv zoo tshaj plaws: Marine hardware, desalination cog Cheebtsam, thiab ntau yam kev lag luam pom.
2. Lub zog ntawm Alloying: Qib 5 (Ti-6Al-4V)
Thaum cov ntawv thov kev lag luam txav mus dhau qhov kev ntxhov siab "nruab nrab" thiab mus rau thaj tsam ntawm kev ua tau zoo, CP titanium tsis txaus. Qhov no yog qhov twg Qib 5, Alpha-Beta alloy, siv rau theem nruab nrab.
6-4 Chemistry
Qib 5 yog tsim los ntawm 90% titanium, 6% aluminium, thiab 4% vanadium. Cov txhuas ua raws li alpha stabilizer (txhim kho lub zog thiab txo qhov ntom), thaum lub vanadium ua raws li beta stabilizer (tso cai rau cov hlau ua kom sov- kho kom muaj zog ntau dua).
Lub zog-rau- Qhov hnyav piv: Qib 5 Titanium Hlau yog qhov muaj zog dua li Qib 2- feem ntau ua ob npaug lossis peb npaug ntawm lub zog tensile-thaum tuav qhov hnyav tib yam. Qhov no ua rau nws yog "cov khoom siv super" rau kev lag luam uas txhua gram tseem ceeb.
Thaum tshav kub kub Resistance: Thaum qib CP pib poob lawv cov qauv kev ntseeg siab ntawm qhov kub siab, Qib 5 tseem nyob ruaj khov, ua rau nws tsim nyog rau cov cav tov thiab tso pa tawm - cov khoom nyob ib sab.
Mechanical Behavior: Tsis zoo li cov qib CP, Qib 5 muaj zog ntau dua. Nws muaj cov nyhuv "caij nplooj ntoos hlav" siab dua, txhais tau hais tias thaum koj khoov qib 5 Titanium Hlau, nws xav rov qab mus rau nws qhov qub. Qhov no ua rau nws nyuaj rau kev tsim tab sis zoo heev rau kev siv caij nplooj ntoos hlav.
Qib 5 ELI (Ntxiv Qes Interstitials)
Ib qho txawv ntawm Qib 5 feem ntau siv nyob rau hauv daim ntawv hlau yog Qib 23 (los yog Qib 5 ELI). Los ntawm kev txo qis cov pa oxygen thiab hlau ntxiv, cov khoom yuav nyuaj dua thiab ntau dua biocompatible, ua rau nws tus qauv kub rau kev kho mob hlau siv hauv cov pob txha staples thiab orthopedic pins.
3. Sib piv cov tshuab ua haujlwm thiab kev ua haujlwm
Txhawm rau xaiv txoj cai Titanium Hlau, ib qho yuav tsum saib qhov sib txawv ntawm cov khoom no.

Weldability thiab Machining
CP qib (1 thiab 2) yog qhov yooj yim heev rau vuam. Vim tias lawv yog cov ntshiab, tsis muaj kev pheej hmoo ntawm kev sib cais ntawm alloy hauv lub pas dej ua ke. Qib 5, thaum weldable, yuav tsum muaj kev tswj xyuas nruj dua ntawm cov cua txias thiab cov roj thaiv thaiv kom tiv thaiv kev tsim cov theem nkig.
Thaum nws los txog rau kev kos cov hlau, Qib 1 tuaj yeem rub los ntawm kev tuag nrog tsawg kawg nkaus lubrication thiab kev pheej hmoo ntawm kev tawg. Qib 5 Titanium Hlau yuav tsum tau tshwj xeeb coatings thiab hnyav - lub luag hauj lwm machinery vim hais tias cov khoom muaj zog thiab thermal conductivity tsawg yuav hnav tawm kos duab tuag sai heev.
4. Xaiv raws li cov qauv kev lag luam
Qhov "txoj cai" Titanium Hlau feem ntau hais los ntawm kev tswj hwm ib puag ncig ntawm kev lag luam.
Aerospace: Yuav luag tsuas yog siv Qib 5 rau cov qauv hlau, kev ruaj ntseg cables, thiab fasteners vim qhov yuav tsum tau ua kom muaj zog thiab qhov hnyav.
Kev Kho Mob: Siv Qib 1 rau nws qhov muag muag hauv qee yam kev siv kho hniav, tab sis cia siab rau Qib 5 ELI rau kev thauj khoom- cov kabmob cog.
Chemical/Marine: Nyiam Qib 2. Nyob rau hauv cov sectors no, tus nqi siab ntawm Qib 5 tsis tshua muaj kev ncaj ncees vim tias thawj hom tsis ua hauj lwm yog corrosion, tsis yog txhua yam snapping. Qib 2 muab cov tshuaj tiv thaiv tsim nyog ntawm tus nqi qis.
Consumer Electronics: Qib 1 thiab 2 yog nrov rau cov hniav hlau los yog mesh qhov "titanium zoo" thiab lub teeb yuag xav tau yam tsis tas yuav tsum muaj kev ntseeg siab heev.
Xaus
Kev xaiv ntawm Qib 1, Qib 2, thiab Qib 5 Titanium Hlau yog qhov kawg xaiv ntawm kev tsim, kev lag luam, thiab lub zog.
Yog tias koj qhov project xav tau ib lub xov hlau uas tuaj yeem ua rau hauv ib qho nyuaj, nruj - vojvoog mesh lossis zoo li ntawm tes, Qib 1 yog koj qhov kev daws teeb meem. Yog tias koj xav tau kev ntseeg siab, tus nqi - cov khoom siv zoo uas tuaj yeem tiv taus cov dej ntsev thiab kua qaub rau ntau xyoo lawm, Qib 2 yog tus qauv kev lag luam. Txawm li cas los xij, yog tias koj daim ntawv thov cuam tshuam nrog kev sib hloov ceev, siab heev, lossis kev ya davhlau- cov khoom siv tseem ceeb, tsuas yog lub zog alloyed ntawm Qib 5 yuav txaus.
Los ntawm kev nkag siab txog cov kev sib txawv ntawm cov metallurgical no, cov tuam ntxhab tuaj yeem txhim kho lawv cov kab ntau lawm, txo cov khoom pov tseg, thiab xyuas kom meej tias lawv cov khoom kawg ua tau raws li cov qauv kev nyab xeeb thiab kev ua haujlwm siab tshaj plaws. Ib txwm txheeb xyuas qib ntawm koj cov Titanium Hlau nrog daim ntawv pov thawj Cov Khoom Siv Xeem (MTR) kom ntseeg tau tias nws ua tau raws li ASTM lossis AMS cov qauv tsim nyog rau koj daim ntawv thov.
