Cov thev naus laus zis tseem ceeb rau kev tsim, kev ua haujlwm thiab kev siv cov khoom siv high-temperature titanium alloy
600 degree high-temperature titanium alloys, nplaim hluav taws-retardant titanium alloys, TiAl alloys, thiab SiCf / Ti composite cov ntaub ntawv yog cov tshiab high-performance high-temperature titanium alloys. Piv nrog rau cov ntaub ntawv zoo tib yam titanium alloy, lawv cov kev loj hlob qis dua. Raws li cov yam ntxwv ntawm kev pabcuam thiab kev tsim cov kev xav tau ntawm cov tshuab siab heev, tshwj xeeb tshaj yog cov rotating qhov chaw siv nyob rau hauv high-temperature ib puag ncig, ib tug loj tus naj npawb ntawm engineering daim ntawv thov kev tshawb fawb yuav tsum tau ua, xws li creep-fatigue-ib puag ncig kev sib cuam tshuam nyob rau hauv high-temperature ib puag ncig. , nplaim retardancy, thiab cov teebmeem micro-texture. Kev cuam tshuam ntawm kev ua haujlwm qaug zog, kev ua haujlwm zoo ntawm lub ntsej muag, sab hauv thiab qhov chaw seem kev ntxhov siab ntawm forgings thiab qhov chaw thiab nws cov kev cuam tshuam rau kev ua haujlwm, kev pabcuam lub neej kev kwv yees thiab tsis ua haujlwm, thiab lwm yam. daim ntawv thov.
High purification thiab homogenization tswj tshuab ntawm industrial ingot Cheebtsam
Lub alloying ntawm TA29, TB12 thiab TiAl alloys yog qhov nyuaj, cov ntsiab lus ntawm alloying ntsiab yog siab, thiab cov yas yog tsawg. Kev npaj ntawm xws li alloy ingots yog nyuaj. Nws yog ib qho nyuaj thiab yooj yim rau kev cais. Siv cov txheej txheem nqus hluav taws xob siv hluav taws xob hluav taws xob hluav taws xob arc rauv melting, tus naj npawb ntawm cov sij hawm melting yuav tsum tau nce kom tsim nyog, thiab cov melting tam sim no, shrinking tam sim no, ingot loj, crucible txias txoj kev, thiab lwm yam yuav tsum tau tswj. Rau TiAl alloys, plasma txias hearth melting txheej txheem yuav siv tau los tsim ingots. Cov txheej txheem txias hearth melting tuaj yeem tshem tawm cov kev suav nrog thiab txhim kho kev sib cais sib cais, uas yog qhov tseem ceeb tshwj xeeb rau titanium alloy cov ntaub ntawv siv hauv qhov tseem ceeb ntawm cov cav tov. Peb lub teb chaws twb muaj ntau yam plasma txias hearth smelting khoom, thiab muaj peev xwm thiab tej yam kev mob ntawm kev soj ntsuam kev tshawb fawb thiab industrial ntau lawm.
Loj-scale bar thiab tshwj xeeb forging npaj technology
Titanium alloy raw cov ntaub ntawv rau aviation forgings feem ntau siv tuav, thiab loj forgings xws li log discs, casings, blisks, thiab kiv cua hniav feem ntau siv Titanium Square Bar. Rau me compressor hniav thiab turbine hniav forgings,Qib 5 Titanium Baryog siv. Raws li cov tshuab siab heev zoo li yuav siv cov qauv qauv ntawm ib qho blisks thiab ib qho blisks, cov kev qhia tshwj xeeb ntawm cov forgings thiab tuav tau nce. Kev tswj qhov sib xws ntawm cov kab loj loj yog qhov tseem ceeb los xyuas kom meej qhov zoo ntawm forgings. Nws yog ib qho tsim nyog los xaiv qhov tsim nyog Advanced forging khoom, optimized tsim forging txheej txheem. Rau ingots ntawm TB12 thiab TiAl alloys, vim lub siab forging deformation kuj ntawm as-cam khwb cia hlau, tsis tshua muaj txheej txheem plasticity, rhiab heev rau deformation kub, thiab yooj yim forging tawg, lub ingots yuav tsum tau npaj los ntawm high-temperature extrusion blanking txheej txheem los npaj loj. -scale tuav, tsis tsuas yog Lub uniformity ntawm deformation tuaj yeem txhim kho, txaus deformation tuaj yeem ua kom ntseeg tau, thiab kev ua haujlwm ntau lawm thiab batch stability ntawm cov tuav kuj tuaj yeem txhim kho.
Lub microstructure thiab crystallographic kev ntxhib los mos ntawm titanium alloys yog lub hauv paus tseem ceeb cuam tshuam rau cov khoom siv kho tshuab, vim yog anisotropy ntawm theem. Tswj cov morphology ntawm microstructure ntawm forgings thiab cov uniformity ntawm microstructure thiab kev ntxhib los mos tsis tsuas yog txhim kho qhov nruab nrab ntawm kev ua tau zoo, tab sis kuj txhim kho cov creep-fatigue cuam tshuam kev ua tau zoo ntawm qhov chaw, uas yog, lub load qaug zog kev ua tau zoo, thiab txo tus naj npawb ntawm qhov sib txawv. pawg. Kev ua tau zoo cov ntaub ntawv dispersion ntawm cov khoom thib ob. Rau cov tshiab high-temperature titanium alloys, tshwj xeeb tshaj yog TiAl alloys, vim hais tias ntawm cov kev taw qhia ntawm cov qauv kev txiav txim, qhov kev ntxhib los mos teeb meem yog ntau nyuaj thiab tseem ceeb, thiab cov cuam tshuam rau high-low voj voog qaug zog kev ua tau zoo thiab load fatigue kev ua tau zoo kuj nyuab dua. Cov qauv thiab kev ntxhib los mos yuav tsum tau tswj nruj me ntsis hauv kev npaj cov tuav thiab forgings.
Integral blisk thiab ib qho blisk qhov chaw machining tshuab
Vim qhov kev txhim kho tas mus li ntawm cov qib kev ua tau zoo ntawm cov tshuab siab heev, ib qho blisks thiab ib qho blisks tau dhau los ua ib qho kev txhim kho. Zuag qhia tag nrho blisk hniav muaj cov qauv complex, tsis zoo channel qhib, nyias hniav, loj dabtsi yog khoov thiab torsion, tsis zoo rigidity, thiab yooj yim deformation. Cov qauv tsim yuav tsum tau siab dua thiab siab dua geometric raug thiab kev ua tau zoo. Guarantees yuav nyuaj thiab nyuaj. Rau qhov tseem ceeb blisk thiab ib qho tseem ceeb nplooj nplhaib ntawm lub compressor nrog me me hniav loj, lub airfoil feem ntau ua tiav los ntawm high-ceev CNC milling txoj kev los tswj lub deformation ntawm ib feem, thiab lub vibration lub teeb kho kom zoo nkauj tshuab yog siv los txhim kho cov residual kev nyuaj siab. ntawm qhov chaw ntawm qhov chaw. Qhov saum npoo yog av thiab abrasive ntws polished, cov hniav zoo li qhov tseeb qhov tseeb, cov hniav zoo li qhov yuam kev tsawg dua 0.1mm, thiab cov hniav nto roughness Ra nce mus txog qib 0.2μm, uas txhim kho qhov zoo ntawm qhov chaw thiab qhov chaw zoo ntawm qhov chaw. Cov txheej txheem electrochemical yuav tsum tau siv los ua cov txheej txheem ntawm TiAl alloy hniav.
Kev tshawb fawb ntawm ultra-high cycle fatigue kev ua tau zoo
Qhov tseeb, tsis muaj lub voj voog qaug zog siab rau cov ntaub ntawv titanium alloy. Ob lub xyoo 1999 thiab 2004 ntawm Cov Txheej Txheem Kev Sib Koom Tes Hauv Lub Cav (ENSIP) hauv Tebchaws Meskas xav kom lub neej qaug zog siab ntawm titanium alloy cav qhov chaw yuav tsum ncav cuag qhov tsawg kawg nkaus ntawm 109 cycles. Raws li qhov kev siv zog txo qis, qhov qaug zog tawg pib txoj hauj lwm zoo li tshwm sim los ntawm qhov chaw mus rau sab hauv. Rau 600 degree kub kub titanium alloy blisks, titanium matrix composite blisks thiab TiAl alloy hniav, qhov qaug zog kev ua tau zoo ntawm cov hniav yog rhiab heev rau kev vibration kev nyuaj siab, yog li lub ultra-high voj voog qaug zog tus cwj pwm thiab kev ua tau zoo yuav tsum tau kawm tag nrho. Kev xaiv tsim nyog ntawm cov txheej txheem txhim kho qhov tsim nyog, xws li laser poob siab ntxiv dag zog thiab qis-plasticity polishing, tuaj yeem txhim kho lub voj voog siab zog ntawm cov hniav thiab tiv thaiv kev puas tsuaj sab hauv thiab kev puas tsuaj los ntawm cov hniav tsis ua haujlwm.
