Hauv kev lag luam xws liaerospace, biomedical engineering, thiab high -kev tsim khoom, titanium alloys tau ntev tau lees paub tias yogcov khoom siv tswv yimua tsaug rau lawv

Txawm li cas los xij, tom qab cov txiaj ntsig no yog qhov kev sib tw loj ntawm kev tsim khoom:

Thaum kub siab, molten titanium reacts nrog yuav luag tag nrho cov pa refractory khoom, uatsoos casting tsis haum rau precision sib sau.

Qhov tshwm sim ntawmpeev casting (poob ciab casting)tau dhau los ua ib qho kev daws teeb meem -pabcomplex geometry, siab precision, thiab ntau lawmntawm titanium Cheebtsam.

Kev nqis peev Casting yog dab tsi? Precision Engineered los ntawm Pib

Kev nqis peev casting yog ibnyob ze -net- txheej txheem tsim khoomuas siv:

Fusible wax los yog resin qauv

Ntau- txheej ceramic plhaub pwm

Txoj kev no enablessiab -precision titanium castingnrog superior nto zoo thiab cov khoom siv.

Core Process Flow ntawm Titanium Investment Casting

Kev Ua Haujlwm Zoo

Nto roughness:Ra Tsawg dua lossis sib npaug li 1.6 μm

Kev siv cov khoom siv:+40% vs forging

Peb Cov Txheej Txheem Tseem Ceeb hauv Titanium Casting

Txawm hais tias nws qhov zoo, titanium peev casting ntsib teeb meem tseem ceeb:

1. Interfacial Reaction (Alpha-Case Formation)

Molten titanium reacts nrog cov ntaub ntawv ceramic (SiO₂, Al₂O₃), ua rau nkig.- txheej txheej, uas:

Txo qaug zog

Yuav tsum tau them nqi tshaj tawm -machining

2. Kev puas tsuaj cua sov

Qhov kub thiab txias:200-300℃instant gradient

Ua rauceramic plhaub cracking

Ua rau casting tsis ua hauj lwm

3. Gas Contamination & Porosity

Kev nqus ntawm hydrogen, oxygen, noo noo

Cov txiaj ntsig hauvinternal porosity defects

Kev lag luam tiag Case

Nyob rau hauv aerospace turbine hniav casting:

Ib txwm Al₂O₃ pwm tsim0.2 hli alpha- rooj plaub txheej

Yuav tsum muaj5 ntxiv machining cov kauj ruam

Cov khoom poob nce mus rau35%

Shell Material Innovation: Tus yuam sij rau kev txwv kev txwv

Kom kov yeej cov teeb meem no, advancedcov ntaub ntawv ceramictau tsim:

1. Carbon-Based Coating Systems

Txo cov kev cuam tshuam ntawm lub ntsej muag

Txhim kho qhov zoo ntawm qhov chaw

2. Oxide Ceramic Gradient Structures

Multi-layer composition design

Zoo dua thermal shock kuj

3. Refractory Hlau Composite Plhaub

High stability ntawm huab cua kub

Txo cov kab mob kom tsawg

Los ntawm Tus Nqi Siab rau Kev Ua Haujlwm Siab: Kev Lag Luam Kev Lag Luam

Kev tsim kho tshiab niaj hnub no tau txhim kho zoo heevnqi efficiency thiab scalability:

Kev txhim kho tseem ceeb

Kev siv cov khoom siv:30% → 92%

Lub sijhawm machining:txo los ntawm 75%

Kev siv hluav taws xob:60% qis dua kev tsim khoom ntxiv (3D luam ntawv)

Kev ua lag luam cuam tshuam

Aerospace: Titanium siv ib lub cav nce los ntawm12 kg → 45 kg

Automotive lightweighting: Nqi txo rau<$15/kg

Medical implants: Lead time shortened rau~ 72 hnu
