Puas yog titanium alloy zoo dua li titanium?
Puas yog titanium alloy zoo dua titanium?
Thaum nws los txog rau cov hlau, muaj ob peb yam uas tuaj yeem ua kom haum rau ntau yam thiab ua haujlwm ntev ntawm titanium. Cov khoom siv hnyav, corrosion-resistant no yog siv rau hauv txhua yam los ntawm dav hlau mus rau kev kho mob cog, ua rau nws yog ib qho tseem ceeb ntawm cov hlau hauv ntiaj teb. Tab sis, nyob rau hauv xyoo tas los no, cov khoom tshiab tau tshwm sim los ua ib qho kev sib tw rau titanium: titanium alloy. Hauv tsab xov xwm no, peb yuav tshawb txog qhov zoo thiab qhov tsis zoo ntawm ob qho khoom siv, thiab sim teb cov lus nug: Puas yog titanium alloy zoo dua li titanium?
titanium yog dab tsi?
Titanium yog cov nyiaj-grey hlau uas paub txog nws lub zog, lub teeb, thiab corrosion-resistant. Pom nyob rau hauv lub xyoo pua 18th lig, titanium yog thawj zaug siv hauv kev lag luam hauv xyoo 1930s, thiab tau pom ntau daim ntawv thov txij thaum ntawd los. Niaj hnub no, titanium yog siv nyob rau hauv aerospace, kev kho mob, thiab automotive kev lag luam, thiab lwm yam. Nws muaj qhov melting point ntawm 1,660 degree (3,020 degree F) thiab qhov ntom ntawm 4.5 g / cm³ (0.163 lb / in³).
Dab tsi yog titanium alloy?
Thaum titanium yog ib yam khoom tseem ceeb ntawm nws tus kheej, nws cov khoom tuaj yeem txhim kho los ntawm kev sib txuas nrog lwm cov hlau. Qhov no yog qhov uas titanium alloy tuaj rau hauv. titanium alloy yog cov khoom tsim los ntawm kev ntxiv lwm cov hlau, xws li vanadium, aluminium, thiab molybdenum, rau titanium. Qhov tshwm sim yog cov khoom siv muaj zog thiab ruaj khov dua uas khaws ntau cov txiaj ntsig ntawm titanium ntshiab.
Qhov zoo ntawm titanium
Ib qho txiaj ntsig tseem ceeb ntawm titanium yog nws lub zog-rau-qhov hnyav piv. Titanium yog ib qho ntawm cov hlau uas muaj zog tshaj plaws thiab lub teeb tshaj plaws hauv ntiaj teb, ua rau nws zoo tagnrho rau kev siv dav hlau thiab lwm yam kev siv uas qhov hnyav yog qhov kev txhawj xeeb. Lwm qhov zoo dua yog nws cov corrosion-resistant. Titanium yog ib qho kev tiv thaiv corrosion, ua rau nws zoo tagnrho rau siv nyob rau hauv ib puag ncig hnyav xws li dej hiav txwv. Nws kuj yog biocompatible, txhais tau hais tias nws muaj kev nyab xeeb los siv hauv kev kho mob cog.
Disadvantages ntawm titanium
Thaum titanium muaj ntau qhov zoo, nws kuj muaj qee qhov tsis zoo. Ib qho ntawm qhov tsis zoo yog nws cov nqi. Titanium yog cov khoom kim heev, ua rau nws tsis tshua muaj kev siv rau qee qhov kev siv. Lwm qhov tsis zoo yog nws cov conductivity tsis zoo. Titanium yog cov khoom siv hluav taws xob tsis zoo ntawm cov cua sov thiab hluav taws xob, uas txwv nws txoj kev siv hauv qee qhov kev siv.
Qhov zoo ntawm titanium alloy
Raws li tau hais ua ntej, titanium alloy muaj ntau yam txiaj ntsig zoo ib yam li titanium ntshiab, tab sis nrog qee qhov zoo ntxiv. Ib qho ntawm qhov zoo tshaj plaws yog nws lub zog. titanium alloy muaj zog dua li titanium ntshiab, ua rau nws zoo tagnrho rau kev siv hauv cov ntawv thov uas muaj zog muaj kev txhawj xeeb, xws li cov dav hlau thiab cov khoom siv ua kis las. Lwm qhov zoo dua yog nws txhim kho corrosion-ua hauj. Titanium alloy tiv taus corrosion ntau dua li cov titanium ntshiab, ua rau nws zoo tagnrho rau siv hauv qhov hnyav hnyav.
Disadvantages ntawm titanium alloy
Thaum titanium alloy muaj ntau qhov zoo, nws kuj muaj qee qhov tsis zoo. Ib qho ntawm qhov tsis zoo yog nws cov nqi. Titanium alloy yog kim dua li ntshiab titanium, ua rau nws tsis tshua muaj kev siv rau qee qhov kev siv. Lwm qhov tsis zoo yog nws qhov txo qis ductility. Titanium alloy yog tsawg dua cov titanium ntshiab, txhais tau hais tias nws tsis tshua muaj peev xwm tiv taus khoov lossis deformation yam tsis muaj kev tawg.

Yog li, titanium alloy zoo dua li titanium? Nws nyob ntawm daim ntawv thov. Ntshiab titanium yog cov khoom siv zoo rau kev siv qhov hnyav, kev tiv thaiv corrosion, thiab biocompatibility tseem ceeb. Titanium alloy, ntawm qhov tod tes, yog qhov zoo dua rau cov ntawv thov uas muaj zog thiab txhim kho corrosion-ua haujlwm tseem ceeb. Ob qho khoom siv muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab kev xaiv ntawm ob yuav nyob ntawm seb qhov kev xav tau tshwj xeeb ntawm daim ntawv thov. Thaum kawg, ob qho tib si titanium thiab titanium alloy yog cov hlau tseem ceeb uas paub tseeb tias yuav txuas ntxiv siv rau ntau yam kev siv rau xyoo tom ntej.
