Cov phooj ywg uas paub txog titanium hlau paub tias muaj ntau yam lus hais txog titanium. Piv txwv, dab tsi yog qhov txawv ntawm titanium hlau, titanium ntshiab, thiab titanium alloy uas peb paub txog? Cia' s qhia luv luv hnub no.
Lub npe -titanium steel tsis yog lub npe kev kawm, tab sis yog lub npe coj mus muag. Vim tias 316L stainless hlau muaj cov xeb zoo dua thiab cov kua qaub thiab alkali tsis kam tshaj li cov hlau tsis huv, cov qauv qib yog 022Cr17Ni12Mo2, uas feem ntau muaj Cr, Ni, thiab Mo, thiab tus lej qhia tau kwv yees feem pua.
Nws tuaj yeem pom tau tias titanium hlau tsis muaj titanium, thiab nws lub ntsiab tivthaiv tseem yog hlau. Kev lag luam lub npe no yog kom paub qhov txawv nws ntawm lwm tus hlau stainless thaum siv los ua cov hniav nyiaj hniav kub, thiab kom tau txais tus nqi ntau dua. Qhov tseeb, tus nqi thiab hws kuj ntawm 316L steel hlau yog qhov tseeb zoo dua li ntawm cov hlau tsis zoo.
Muaj feem ntau ob hom ntawm titanium uas yuav tsum tau hu ua titanium, ib tug yog dawb huv titanium, thiab lwm yam yog titanium hlau.
Cov ntsiab lus siab tshaj plaws ntawm titanium yog cov freshly los ua daim txhuam cev titanium, uas yog tsim los ntawm titanium tetrachloride txo los ntawm magnesium. Nws zoo li qhov no:
yog xoob thiab ntxeem tau, nws lub zog muaj peev xwm tsawg, thiab nws tsis tuaj yeem siv ncaj qha raws li cov khoom siv titanium. Nws yog cov khoom siv ntau tshaj plaws ntawm cov khoom siv titanium. Tom qab smelting, forging thiab dov, nws tiav mus rau hauv ntau yam duab ntawm cov phiaj, nyob ntawm tej, hlab, thiab lwm yam
Cov ntsiab lus ntsiab lus ntawm titanium sponge titanium yog ze rau 100%. Tab sis titanium yog heev active, thiab nws yuav yooj yim hnov mob nrog rau oxygen, nitrogen, hydrogen, thiab lwm yam nyob rau hauv cov huab cua thaum raug rau saum huab cua, ces nws yog yuav luag tsis yooj yim sua kom ua tau 100% kev coj dawb huv.
Feem ntau hais lus, cov uas muaj cov ntsiab lus titanium ntau dua 95% dhau los ua kev lag luam titanium ntshiab. Cov ntshiab titanium tau muab faib ua GR1-GR4 raws li qhov sib txawv ntawm cov ntsiab lus titanium thiab cov ntsiab lus tsis huv. Peb feem ntau muaj GR1 thiab GR2. Kev ua haujlwm tsis zoo yog cov pa oxygen, nitrogen, hydrogen, carbon, hlau thiab lwm yam. Qhov ntau dua ntawm cov ntsiab lus titanium, cov softer nws yog. Peb hais tias qis dua lub zog, tab sis qhov zoo dua nws cov tawv.
Yog li ntawd thaum peb ua titanium siv buckles thiab titanium hniav nyiaj hniav kub, peb yuav siv GR1 khoom uas tus quab yuam yog tsis muaj zog, thaum shafts thiab me me screws yuav siv GR2 khoom.
Thaum peb ua cov khob titanium ntshiab, peb tsis tuaj yeem siv GR2. Qhov siab dua qhov kev coj dawb huv, qhov zoo dua, tshwj xeeb tshaj yog cov ntsiab lus hydrogen yuav tsum muaj tsawg, txwv tsis pub nws yuav yooj yim tawg vim tsis muaj qhov tawv txaus, lossis yuav muaj cov kab kev pom tseeb ntxiv. Los yog pitting, tus nqi seem yuav yog siab kawg.
Titanium alloy, raws li lub npe qhia, yog ib qho txhuas tsim los ntawm titanium thiab lwm yam hlau thiab tsis siv hlau. Cov hlau no thiab tsis muaj hlau xws li txhuas, molybdenum, vanadium, chromium, hlau, zirconium, tin, oxygen, carbon, thiab lwm yam Titanium alloys tau muab faib ua TA, TB, thiab TC series raws li cov qauv sib txawv ntawm cov duab hlau. Tsis txhob delve rau hauv nws ntawm no.
Coj cov feem ntau siv GR4 titanium alloy ua piv txwv. Nws cov ntsiab lus titanium yog 90%, txhuas 6%, thiab vanadium 4%, yog li nws tseem hu ua titanium 6 aluminium 4 vanadium. TC4 titanium alloy yog qhov pib tsim thiab siv ntau tshaj plaws ntawm titanium alloy nyob hauv lub ntiaj teb. Nws tseem yog qhov ntxov tshaj plaws titanium alloy siv nyob rau hauv kev kho mob. Nws cov txiaj ntsig tso tawm rau ntau tshaj tag nrho cov khoom lag luam ntawm ntau cov titanium alloy khoom hauv ntiaj teb. Nws yog qhov tseem ceeb tshaj plaws hauv kev lag luam aerospace. Ntau dua 80%. Nws muaj cov tshuaj tiv thaiv corrosion siab, siab zog dua li titanium ntshiab, zoo toughness, kuj yooj yim ua thiab vuam, yog li kev ua haujlwm tag nrho yog qhov zoo heev, thiab zoo li titanium ntshiab, nws yuav tsis ua rau ua xua.
Yog ntshiab titanium zoo dua los yog titanium hlau?
Qhov no yog tsis txhij. Ntaub ntawv sib txawv yog haum rau txawv cov khoom. Feem ntau hais lus, tsis suav cov xwm txheej xws li cov duab, cov khoom siv tus nqi ntawm titanium alloy yog siab dua qhov ntawm titanium ntshiab. Tau kawg, cov titanium alloy ntawm no xav tau cov qhab nia tsis tu ncua, uas yog los ntawm titanium thiab lwm yam hlau thiab tsis muaj hlau yog ntxiv, es tsis txhob ntxiv me ntsis titanium rau lwm cov hlau, thiab yog tias nws muaj titanium me ntsis, nws yuav ua txuj ua li ib cov titanium alloy.
