Taw qhia Ntawm Industrial Ntshiab Titanium

Industrially ntshiab titanium yog graded raws li cov ntsiab lus ntawm impurity ntsiab. Nws muaj cov txheej txheem stamping zoo heev thiab cov khoom siv vuam, yog qhov tsis hnov ​​​​tsw rau kev kho cua sov thiab lub koom haum hom, thiab muaj qee lub zog nyob rau hauv kev txaus siab plasticity. Nws lub zog yog nyob ntawm cov ntsiab lus ntawm cov ntsiab lus interstitial oxygen thiab nitrogen. Nws muaj kev tiv thaiv corrosion siab hauv dej hiav txwv, tab sis tsis zoo nyob rau hauv inorganic acids. Feem ntau siv rau hauv kev tsim khoom ntawm ntau yam phaj lossis forgings uas ua haujlwm ntawm qhov kub ntawm -253 mus txog 350 degree thiab tsis raug quab yuam ntau, thiab tseem tuaj yeem siv rau hauv kev tsim cov rivets hlau thiab cov raj.
Alpha-phase titanium muaj qee qhov nyiaj ntawm oxygen, nitrogen, carbon, silicon, hlau thiab lwm yam impurities. Dirtual Metallic Titanium nrog lub titanium cov ntsiab lus ntawm tsis tsawg dua 98%, muaj ib qho pa roj oxygen tsawg dua li 98%, cov pa roj carbon, silicon thiab lwm yam tsis huv. Oxygen, nitrogen, carbon, hydrogen thiab silicon belongs rau lub interstitial impurity ntsiab, thiab hlau belongs rau lwm yam -stabilizing ntsiab. Oxygen, nitrogen thiab carbon tuaj yeem ua rau chav tsev kub tensile lub zog ntawm titanium, tab sis kuj txo cov plasticity ntawm titanium, yog li cov ntsiab lus ntawm oxygen, nitrogen thiab carbon nyob rau hauv titanium muaj kev txwv nruj, tshwj xeeb tshaj yog cov ntsiab lus oxygen. Lub solubility ntawm hydrogen nyob rau hauv titanium yog heev me me, thiab cov tshuaj tiv thaiv ntawm hydrogen thiab titanium yog reversible. Lub ntsiab nyhuv ntawm hydrogen ntawm titanium kev ua tau zoo yog manifested li "hydrogen embrittlement", thaum lub hydrogen ntsiab lus ntawm titanium ncav cuag ib tug npaum li cas, yuav ua rau kom cov titanium rhiab heev rau lub notch, uas sharply txo cov notched specimen cuam tshuam toughness thiab lwm yam khoom. Feem ntau hais tias cov ntsiab lus hydrogen ntawm titanium yuav tsum tsis pub tshaj 0.015%. Titanium yog niaj hnub cosmic aviation science, marine science thiab nuclear fais fab tiam thiab lwm yam kev tshawb fawb thiab kev lag luam indispensable cov ntaub ntawv. Titanium yog 48% sib zog dua cov hlau dav dav, thiab toughness, acid thiab alkali tsis kam, corrosion kuj, siab stability, siab zog, zoo elasticity thiab lwm yam zoo, raws li lub Department of ergonomics, titanium yog non-toxic rau tib neeg lub cev. , tsis muaj hluav taws xob.
Cov qib zoo ntawm industrially ntshiab titanium yog: Gr-1, Gr-2, Gr-3, Gr-4 ntawm ASTM ntawm Tebchaws Meskas; classl, 2, 3 ntawm JIS ntawm Nyiv; 115, 125, 130, 155, 160 ntawm IMI ntawm United Kingdom; 3.7025, 3.7035, 3.7055, 3.7065 ntawm DIN ntawm lub teb chaws Yelemees; Tuam Tshoj cov khoom lag luam ntshiab titanium qib yog deformed Muaj ntshiab titanium TA1, TA2, TA3; cam khwb cia muaj ntshiab titanium ZTAl, ZTA2, ZTA3.

Kev lag luam ntshiab titanium feem ntau yuav tsum tau ua ob lub tshuab nqus tsev (tsawg kawg yog ib qho ntawm cov khoom siv hauv lub tshuab nqus tsev vacuum electrode arc rauv) melting, thiab nws cov castings feem ntau yog tsim nyob rau hauv lub tshuab nqus tsev plhaub. Industrial ntshiab titanium tuaj yeem tiv taus ob qho tib si kub thiab txias ua haujlwm. Txij li thaum titanium yooj yim absorbs oxygen, hydrogen thiab nitrogen thaum rhuab, uas txo cov plasticity thiab deteriorates zog, yuav tsum tau saib xyuas kom lub cub tawg cua nruab nrab los yog me ntsis oxidizing thaum rhuab, thiab sim kom tsis txhob siv los txo cov cua, tsis txhob hais txog kev siv. ntawm hydrogen cua sov. Yuav forged, extruded, dov thiab stretched nyob rau hauv lub niaj zaus cov cuab yeej rau kev ua, nws thermal ua kub ntau yam ntawm 800 ~ 900 degree. Thaum ua haujlwm txias tau ua tiav, qhov nruab nrab annealing yuav tsum tau nqa tawm thaum tus nqi ua haujlwm txias nce mus txog ib qho nqi (xws li 30% mus rau 60%).
Kev lag luam ntshiab titanium txiav zoo ib yam li austenitic stainless hlau, tab sis vim muaj cov tshuaj lom neeg muaj zog ntawm titanium, tsis zoo thermal conductivity, cov cuab yeej nto muaj qhov zoo sib xws, yog li cov txheej txheem txiav tshwj xeeb thiab cov hlau yuav tsum sib txawv. Kev siv cov cuab yeej ua haujlwm ntse gorlg, pub loj, txiav qis qis thiab cov roj soluble coolant, nrog rau kev ua haujlwm tsis zoo, tuaj yeem ua cov txheej txheem txiav. Muaj ntshiab titanium yog haum rau txhua yam ntawm vuam, nrog zoo fluidity nyob rau hauv weld cheeb tsam. Muaj ntau txoj kev vuam, feem ntau siv hauv kev lag luam yog argon gas shielded arc vuam.
Vim muaj cov ntshiab titanium muaj kev ua tau zoo thiab zoo heev corrosion kuj, yog li nws tau dhau los ua cov khoom siv tsis tseem ceeb rau ntau qhov chaw lag luam. Thiab raws li cov khoom siv cog qoob loo, nws tau siv dav hauv kev kho mob txij li xyoo 1960. Ntawm tag nrho cov feem ntau siv implantable hlau cov ntaub ntawv, titanium muaj zoo biocompatibility, thiab vim hais tias nws qhov ntom thiab elasticity yog ze rau ntawm tib neeg cov pob txha, thiab nws tsis yog-magnetic, yog li ntawm peb loj hlau cog cov ntaub ntawv, namely stainless hlau, cobalt-chromium. -molybdenum alloy, thiab titanium, titanium yog ib qho ntawm cov khoom lag luam zoo tshaj plaws. Daim ntawv thov ntawm titanium tau daws ntau yam teeb meem loj engineering thiab technical, txhawb kev tshawb fawb thiab thev naus laus zis, thiab coj cov txiaj ntsig kev lag luam, thaum muaj kev ua tau zoo thiab muaj peev xwm zoo ntawm titanium, thiab ua kom pom nws daim ntawv thov ntawm qhov kev cia siab dav dua.
