Dab tsi yog qhov txawv ntawm titanium hlau, ntshiab titanium thiab titanium alloy?
Lub npe titanium steel tsis yog lub npe kev kawm txuj ci, tab sis yog lub npe lag luam. Lub npe hu ua titanium hlau yog ib hom stainless hlau uas tsis muaj titanium. Cov khoom siv tsis yog titanium, tab sis 316L stainless hlau. Nws yog hu ua titanium hlau kom nyiam cov neeg. Qee tus txawm hu nws titanium alloy hniav nyiaj hniav kub, tab sis nws yog cov khoom siv stainless hlau uas tsis muaj titanium. Tus nqi ntawm cov hniav nyiaj hniav kub ua los ntawm nws cov khoom yog qis dua lwm yam kub thiab nyiaj hniav nyiaj hniav kub.
Nws tuaj yeem pom tias titanium hlau tsis muaj titanium, thiab nws cov khoom tseem ceeb yog hlau. Titanium hlau tsuas yog txawv ntawm lwm cov hlau tsis muaj steel thaum siv los ua cov hniav nyiaj hniav kub thiab muaj tus nqi siab. Tus nqi thiab corrosion kuj ntawm 316L stainless hlau yog qhov zoo dua li cov hlau tsis zoo tib yam.
Txawm li cas los xij, dab tsi tuaj yeem hu ua titanium cov ntaub ntawv feem ntau muab faib ua ob pawg: ib qho yog titanium ntshiab, thiab lwm yam yog titanium alloy.
titanium ntshiab yog titanium nrog cov ntsiab lus titanium ntau dua 99.%. Nws tsis yog tov nrog tej yam hlau. Cov ntsiab lus titanium siab tshaj plaws yog cov khoom siv tshiab titanium, uas yog tsim los ntawm titanium tetrachloride txo los ntawm magnesium. Nws mus zoo li no:
Nws yog xoob thiab ntxeem tau nrog lub zog tsawg heev thiab tsis tuaj yeem siv ncaj qha raws li cov khoom siv titanium. Nws yog cov khoom siv tshaj plaws ntawm cov khoom siv titanium. Nws yog ua tiav rau hauv ntau yam duab ntawm daim hlau, xov hlau, raj, thiab lwm yam tom qab smelting, forging, thiab dov.
Cov ntsiab lus titanium ntawm titanium daim txhuam cev yog ze rau 100%. Txawm li cas los xij, titanium nquag nquag thiab tuaj yeem ua rau cov pa oxygen, nitrogen, hydrogen, thiab lwm yam hauv huab cua thaum raug huab cua, yog li nws yuav luag tsis tuaj yeem ua tiav 100% purity.
Feem ntau hais lus, yog tias cov ntsiab lus titanium siab dua 95%, nws dhau los ua kev lag luam ntshiab titanium. titanium ntshiab yog muab faib ua TA1-TA4 raws li cov ntsiab lus titanium thiab impurity cov ntsiab lus. Feem ntau peb siv TA1 thiab TA2. Cov impurities feem ntau yog cov pa oxygen, nitrogen, hydrogen, carbon, hlau, thiab lwm yam. Qhov siab dua cov ntsiab lus titanium, nws yog softer thiab qis dua nws lub zog, tab sis qhov zoo dua nws cov toughness.
Yog li ntawd, thaum peb ua titanium siv buckles thiab titanium hniav nyiaj hniav kub, peb yuav siv TA1 cov khoom nyob rau hauv qhov chaw uas tsis muaj zog quab yuam, thiab TA2 khoom yuav siv tau rau shafts thiab me me screws.
Thaum peb ua cov khob titanium ntshiab, peb siv tsis tau TA2. Qhov siab dua qhov purity, qhov zoo dua. Hauv particular, cov ntsiab lus hydrogen yuav tsum tsawg, txwv tsis pub nws yuav yooj yim tawg vim tsis txaus toughness, los yog yuav pom tseeb stretch kab. Los yog pitted, tus nqi seem yuav siab heev.
Cia peb tham txog titanium alloy. Raws li lub npe qhia, nws yog ib qho alloy tsim los ntawm titanium thiab lwm yam hlau thiab tsis yog hlau. Cov hlau thiab cov hlau tsis yog hlau xws li txhuas, molybdenum, vanadium, chromium, hlau, zirconium, tin, oxygen, carbon, thiab lwm yam. Titanium alloys muab faib ua TA, TB, thiab TC series raws li cov qauv metallographic sib txawv. Kuv yuav tsis mus rau hauv cov ntsiab lus ntawm no.
Siv cov feem ntau siv TC4 titanium alloy ua piv txwv. Nws cov ntsiab lus titanium yog 90%, aluminium 6%, thiab vanadium 4%, yog li nws tseem hu ua titanium 6 aluminium 4 vanadium. TC4 titanium alloy yog qhov ntxov tshaj plaws tsim thiab feem ntau siv titanium alloy hauv ntiaj teb. Nws kuj yog qhov ntxov tshaj plaws titanium alloy siv hauv kev kho mob. Nws cov zis tso nyiaj rau ntau tshaj li ib nrab ntawm tag nrho cov zis ntawm ntau yam titanium alloy khoom nyob rau hauv lub ntiaj teb no, tshwj xeeb tshaj yog nyob rau hauv lub aerospace kev lag luam. Ntau tshaj 80%. Nws muaj cov khoom tiv thaiv corrosion siab, muaj zog dua cov ntshiab titanium, muaj cov tawv tawv zoo, thiab yooj yim rau txheej txheem thiab vuam, yog li nws cov kev ua tau zoo tag nrho, thiab nws tsis ua rau muaj kev fab tshuaj zoo li titanium ntshiab.
Yog li qhov twg yog qhov zoo dua, ntshiab titanium lossis titanium alloy?
Qhov no yog inconclusive. Cov khoom sib txawv yog tsim rau cov khoom sib txawv. Feem ntau hais lus, tsis suav nrog cov yam ntxwv xws li cov tsos, cov khoom siv ntawm titanium alloy yog siab dua li ntawm cov ntshiab titanium. Tau kawg, titanium alloy ntawm no yuav tsum yog qib ib txwm muaj, uas yog raws li titanium thiab ntxiv nrog lwm cov hlau thiab cov hlau tsis muaj hlau, tsis yog ntxiv me ntsis titanium rau lwm cov hlau thiab ua txuj ua titanium alloy yog tias nws muaj me ntsis. titanium. Kuv vam tias cov neeg siv khoom tuaj yeem siv ntau qhov kev xav, ua kom lawv lub qhov muag qhib, thiab yuav cov khoom tsim nyog rau lawv cov nyiaj.
