Nws cov khoom tshwj xeeb ntawm hardness thiab lub zog ua rau titanium cov khoom ntawm kev xaiv rau ntau daim ntawv thov high-end. Tsab ntawv xov xwm no yuav muab kev tshuaj xyuas qhov tob ntawm lub cev thiab tshuaj lom neeg ntawm titanium thiab ntsuas nws qhov kev ua tau zoo thiab kev txhim kho yav tom ntej hauv ntau qhov chaw thov.
I. titanium nyuaj npaum li cas?
Lub hardness ntawm ntshiab titanium yog HV280-300, thaum lub hardness ntau yam ntawm titanium alloy yog HV280-340, uas belongs rau nruab nrab hardness range tab sis muaj lub zog siab, uas qhia tau hais tias titanium alloys mas paub rau lawv. lub zog ntau dua li hardness. Lub hardness ntawm titanium alloy yog qis dua li ntawm cov hlau quenched, tab sis nws yuav zoo dua tom qab kev kho nitriding. Txawm li cas los xij, nws tseem tsis yog nyuaj li silicon carbide, boron carbide thiab lwm yam khoom siv high-hardness. Kev sib raug zoo ntawm hardness thiab lub zog ntawm titanium alloys txawv ntawm cov ntaub ntawv hlau. Hardness tsis ncaj nraim rau lub zog. Titanium alloy muaj lub zog siab thiab qhov ntom ntom, thiab muaj cov khoom siv zoo, tawv thiab corrosion kuj.
II. Cov yam ntxwv muaj zog ntawm titanium
Lub zog ntawm ntshiab titanium nyob ntawm qhov ntsuas sib txawv. Lub zog tawm los yog kwv yees li ntawm 240MPa thiab 550MPa, thiab lub zog tensile yog kwv yees li ntawm 345MPa thiab 895MPa.
1.Yield zog
Lub zog tawm los yog qhov tseem ceeb ntawm cov khoom siv pib deform raws li kev quab yuam. Qhov siab dua lub zog tawm los, qhov nyuaj dua nws yog rau cov khoom kom deform. Lub zog tawm los ntawm titanium ntshiab yog kwv yees li ntawm 240MPa thiab 550MPa, uas yog qib siab. Nyob rau hauv kev sib piv, lub zog tawm los ntawm txhuas alloys feem ntau yog nyob nruab nrab ntawm 80MPa thiab 570MPa, tab sis lub zog ntawm cov hlau feem ntau siab dua li cov ntshiab titanium.
2. Lub zog tensile
Lub zog tensile yog hais txog tus nqi tseem ceeb uas cov khoom tsis ua raws li lub zog tensile. Qhov siab dua lub zog tensile, qhov nyuaj nws yog rau cov khoom tawg. Lub zog tensile ntawm ntshiab titanium yog kwv yees li ntawm 345MPa thiab 895MPa, uas yog sib npaug rau qib ntawm yield zog. Hauv kev sib piv, lub zog tensile ntawm aluminium alloys feem ntau yog nruab nrab ntawm 120MPa thiab 605MPa, thiab lub zog tensile ntawm cov hlau feem ntau siab dua li cov ntshiab titanium.
III. Daim ntawv thov teb ntawm titanium
1>Aerospace: Titanium alloys yog siv nyob rau hauv aircraft cav thiab fuselage qauv vim lawv lub zog siab thiab tsawg ntom.
2>Cov khoom siv kho mob: Titanium's biocompatibility thiab lub zog ua rau nws nyiam cov khoom siv rau cov pob txha thiab cov khoom cog.
3>Kev tsim khoom lag luam: Titanium lub zog siab thiab corrosion kuj yog dav siv hauv tsheb, tsheb kauj vab ncej thiab cov khoom siv tshuaj.
IV. Titanium kev ua haujlwm thiab kev ua haujlwm zoo
1>Kev siv thev naus laus zis: Los ntawm kev ua haujlwm txias thiab kev kho cua sov, microstructure ntawm titanium tuaj yeem hloov kho thiab nws qhov tawv thiab lub zog tuaj yeem txhim kho.
2>Alloy txoj kev loj hlob: Alloying thev naus laus zis, xws li ntxiv aluminium, vanadium thiab lwm yam khoom, tuaj yeem txhim kho cov khoom siv ntawm titanium.
3>Kev kho deg: Nto txheej thiab anodizing thiab lwm yam kev kho mob technologies txhim khu kev hnav tsis kam thiab corrosion kuj ntawm titanium.
V. Corrosion kuj ntawm titanium
1>Kev ruaj ntseg tshuaj: Titanium muaj kev tiv thaiv corrosion zoo heev thiab tseem ruaj khov txawm tias nyob hauv dej hiav txwv thiab chloride ib puag ncig.
2>Cov khoom tiv thaiv: Qhov no ua rau titanium nrov heev hauv kev lag luam marine engineering, shipbuilding thiab chemical processing industries.
VI. Kev lag luam thiab kev ruaj ntseg ntawm titanium
1>Tus nqi-zoo: Txawm hais tias titanium kim dua rau kuv thiab cov txheej txheem, nws lub neej ntev thiab kev saib xyuas tsis zoo muab cov txiaj ntsig zoo.
2>Kev cuam tshuam ib puag ncig: Kev cuam tshuam ib puag ncig thaum lub sijhawm tsim cov txheej txheem titanium yog qhov me me thiab ua tau raws li qhov yuav tsum tau muaj ntawm kev txhim kho kom ruaj khov.
Titanium hardness thiab lub zog, ua ke nrog nws lub teeb yuag, corrosion-resistant thiab biocompatible khoom, ua rau nws yog ib qho tseem ceeb heev engineering khoom. Raws li kev siv thev naus laus zis thiab kev siv tshiab txuas ntxiv tsim, lub peev xwm ntawm titanium yuav raug tshawb nrhiav ntxiv. Txawm hais tias muaj kev sib tw nqi, titanium tseem muaj cov ntawv thov dav dav, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas xav tau kev ua haujlwm siab. Nrog rau kev nkag siab tob dua ntawm cov ntaub ntawv titanium thiab kev txhim kho ntawm kev ua cov thev naus laus zis, peb tuaj yeem cia siab tias titanium yuav ua lub luag haujlwm ntau dua hauv kev lag luam thiab kev kho mob yav tom ntej.
