Titanium alloys thiab tungsten alloys

Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho kev lag luam, ob qho kev ua haujlwm siab, tungsten alloy thiab titanium alloy, tau siv dav hauv ntau lub teb. Lawv tau nyiam ntau xim vim lawv cov khoom siv zoo heev, zoo corrosion kuj thiab kub ua haujlwm. Yog li, dab tsi yog qhov txawv ntawm tungsten alloy thiab titanium alloy?

Tungsten alloy yog ib qho alloy uas muaj tungsten ua lub hauv paus thiab ntxiv cov ntsiab lus xws li npib tsib xee, cobalt, thiab hlau. Tungsten alloy muaj cov yam ntxwv hauv qab no:
⑴High ceev: Tungsten alloy muaj qhov ntom ntom, feem ntau yog nruab nrab ntawm 16-20g/cm3, uas yog ntau tshaj ob npaug ntawm cov hlau. Qhov siab ceev ua rau tungsten alloy muaj qhov zoo thiab tuaj yeem tiv taus sab nraud thiab siab.

⑵ High hardness: Tungsten alloy muaj hardness siab heev, feem ntau ntawm 8-9 ntawm Mohs hardness scale. Lub siab hardness ua rau tungsten alloy heev hnav-resistant thiab yuav siv tau nyob rau hauv siab load thiab siab sib txhuam daim ntaub ntawv.

⑶High melting point: Lub melting point ntawm tungsten alloy yog qhov siab, feem ntau ntawm 3420-3800 degree . Lub siab melting point ua rau tungsten alloy muaj qhov kub thiab txias tsis kam thiab tuaj yeem siv rau hauv qhov kub thiab txias.

⑷ Zoo corrosion kuj: Tungsten alloy muaj corrosion kuj zoo nyob rau hauv ib txwm kub thiab siab, thiab muaj peev xwm tiv taus corrosion ntawm feem ntau acids, alkalis thiab ntsev.

Titanium alloy yog ib qho alloy uas muaj titanium ua lub hauv paus thiab ntxiv cov ntsiab lus xws li txhuas, vanadium, thiab zirconium. Titanium alloy muaj cov yam ntxwv hauv qab no:
⑴ Lub teeb yuag: Qhov ceev ntawm titanium alloy yog tsawg, feem ntau yog nruab nrab ntawm 4-5g / cm3, uas yog li ib feem peb ntawm qhov ntom ntawm cov hlau. Lub teeb hnyav ua rau titanium alloys muaj qis dua, uas tuaj yeem txo qhov hnyav ntawm cov qauv.

⑵ Lub zog siab: Titanium alloy muaj zog heev, feem ntau ntawm 800-1000MPa. Lub zog siab ua rau cov titanium alloys muaj peev xwm thauj khoom zoo thiab tuaj yeem siv rau hauv cov xwm txheej nyuaj.

⑶ Zoo corrosion kuj: Titanium alloy muaj corrosion kuj zoo nyob rau hauv ib txwm kub thiab siab, tshwj xeeb tshaj yog nyob rau hauv seawater.

⑷ Zoo biocompatibility: Titanium alloy muaj biocompatibility zoo thiab yog dav siv hauv kev kho mob, xws li cov pob qij txha, implanted stents, thiab lwm yam.

⑴ Ceev: Qhov ceev ntawm tungsten alloy yog siab dua li ntawm titanium alloy, uas txhais tau hais tias tungsten alloy hnyav dua thiab muaj zog tiv thaiv thiab siab ua haujlwm. Titanium alloys muaj qis ceev thiab yog qhov tsim nyog rau cov ntawv thov uas yuav tsum tau ua kom zoo.

⑵ Hardness: Tungsten alloy muaj hardness siab dua titanium alloy thiab muaj kev hnav zoo dua. Txawm li cas los xij, hauv qee qhov xwm txheej uas yuav tsum tau ua haujlwm zoo, qhov qis dua ntawm titanium alloys ua kom zoo dua.

⑶ Melting point: Lub melting point ntawm tungsten alloy yog siab dua li ntawm titanium alloy, thiab nws kub kuj zoo dua. Txawm li cas los xij, titanium alloys muaj oxidation zoo dua thaum kub kub.

⑷ Corrosion kuj: Ob leeg tungsten alloy thiab titanium alloy muaj corrosion kuj zoo nyob rau hauv ib txwm kub thiab siab, tab sis nyob rau hauv tej qhov chaw, xws li seawater ib puag ncig, titanium alloy muaj zoo corrosion kuj.

Tungsten alloy feem ntau yog siv rau hauv kev ua haujlwm siab, kev sib txhuam siab, thiab kev cuam tshuam-resistant daim ntaub ntawv, xws li cov cuab yeej txiav, laum khoom, pwm, thiab lwm yam. titanium alloys feem ntau yog siv rau hauv lub teeb yuag, siab zog, thiab corrosion-resistant daim ntaub ntawv xws li aviation. , aerospace, thiab kev kho mob.

Yuav kom suav tau, tungsten alloy thiab titanium alloy txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab cov ntawv thov tshwj xeeb yuav tsum raug xaiv raws li qhov xav tau tiag tiag thiab ib puag ncig. Nrog kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, nws ntseeg tau tias tungsten alloys thiab titanium alloys yuav ua lub luag haujlwm ntau dua hauv ntau thaj chaw.
