titanium qib twg yog qhov zoo tshaj plaws
Qib 5 titanium alloys yog dav siv titanium cov ntaub ntawv. Xws li Qib 5 Titanium Phaj nws lub zog siab, lub teeb yuag, kev tiv thaiv corrosion, ua rau qib no tuaj yeem siv rau ntau daim ntawv thov. Ib qho kev lag luam feem ntau yog aerospace. Nws tuaj yeem muaj hnub nyoog hardened los ntawm kev kho cua sov kom muaj zog dua. Qee qhov kev siv ntawm cov khoom siv no yog dav hlau tshuab compressor hniav, discs thiab rings; airframe Cheebtsam; cov hlab ntsha siab; foob pob hluav taws motor casings; nyoob hoom qav taub rotor hubs thiab tseem ceeb forgings uas yuav tsum tau ib tug siab zog-rau-qhov hnyav piv. Cov khoom siv biocompatible no kuj zoo tagnrho rau kev cog qoob loo kho mob.
Qib 5 alloy yog lub zog nruab nrab alpha-beta ob-theem titanium alloy uas muaj 6% alpha stabilizing element AI thiab 4% beta stabilizing element V. Cov hlau no muaj cov khoom zoo heev thiab tau txais cov ntawv thov dav tshaj plaws hauv kev lag luam aviation thiab aerospace. Lub sijhawm ua haujlwm ntev ntawm cov hlau tuaj yeem ncav cuag 400 degree. Hauv kev lag luam aviation, nws tsuas yog siv los tsim cov kiv cua thiab compressor disks thiab cov hniav ntawm lub cav, nrog rau cov khoom tseem ceeb ntawm cov kabmob xws li kab teeb, cov pob qij txha thiab cov bulkheads hauv cov qauv dav hlau.
Cov khoom lag luam tseem ceeb ntawm Qib 5 titanium alloy yogQib 5 Titanium Bar, Qib 5 Titanium Forging, Qib 5 Titanium Phaj, profiles thiab xov hlau, thiab lwm yam. Cov hlau alloy feem ntau yog siv rau hauv lub xeev annealed, thiab tseem tuaj yeem ua kom muaj zog los ntawm kev kho kev laus, tab sis qhov hardened cross seem feem ntau tsis ntau tshaj 25mm.
Cov hlau muaj cov txheej txheem zoo plasticity thiab superplasticity, thiab tsim nyog rau ntau yam kev sib sau. Lub alloy tseem tuaj yeem welded thiab machined nyob rau hauv ntau txoj kev.
Kev kho cua sov txheej txheem ntawm qhov chaw
1) Thaum annealing semi-tiav khoom lossis qhov chaw, lub sijhawm tuav nyob ntawm qhov tuab ntawm ntu. Thaum lub thickness ntawm seem yog tsawg dua los yog sib npaug rau 10 hli, lub sij hawm tuav yuav tsum tsis pub tshaj 30min; thaum lub thickness yog 11-50mm, nws yog 30-60min; thaum nws loj dua 50mm, nws yog 1-2h.
2) Ntau hom hluav taws xob cua sov siv rau kev kho cua sov ntawm qhov chaw, thiab lub cub tawg yuav tsum tau muab ntxuav kom huv si ua ntej kev kho mob. Thaum siv cov roj los yog roj rauv cua sov, cov cua hauv lub qhov cub yuav tsum nruj me ntsis tswj kom muaj qhov cua oxidizing me ntsis, thiab kev saib xyuas yuav tsum tsis txhob tsuag cov combustion nozzle ncaj qha mus rau qhov chaw.
3) Ua ntej lub tshuab nqus tsev annealing, oxide daim tawv nqaij thiab cov pa nplua nuj txheej ntawm cov khoom yuav tsum tau muab tshem tawm, thiab cov roj yuav tsum tau ua tib zoo tshem tawm ua ntej nkag mus rau hauv qhov cub. Thaum lub tshuab nqus tsev annealing qhov chaw nrog cov duab complex, fixtures yuav tsum tau siv los txo qhov deformation ntawm qhov chaw. Nyob rau hauv lub cub tawg qhov chaw yog nyiam dua nrog pre-degassed titanium oxide-dawb chips los tiv thaiv oxidation ntawm qhov chaw.
Cov txheej txheem kho deg
1) Txhawm rau txhim kho qhov qaug zog ntawm titanium alloy qhov chaw, qhov chaw txhaj tshuaj peening tuaj yeem ua tau. Feem ntau, kev txhaj tshuaj steel nrog txoj kab uas hla ntawm 2-5mm yog siv, uas tuaj yeem tsim qhov kev ntxhov siab ntawm qhov chaw ntawm 785MPa, thiab qhov tob ntxiv dag zog yog li 200μm. Kev txhaj tshuaj peening tuaj yeem txhim kho lub zog qaug zog ntawm TC4 alloy.
2) Txhawm rau txhim kho qhov hnav tsis kam ntawm Qib 5 titanium alloy, qhov chaw uas nquag hnav, xws li sab ntawm lub rooj damping ntawm lub kiv cua, yog txau nrog cov khoom siv hluav taws xob zoo li tungsten carbide thiab chromium carbide los ntawm plasma los yog explosive spraying. Txoj kev no tseem tuaj yeem siv los kho qhov hnav ntawm titanium alloy qhov chaw.
3) Txhawm rau kom tsis txhob khawb thiab sib txuas ntawm titanium alloy qhov chaw thaum ua haujlwm, anodizing, chrome plating, tshuaj npib tsib xee plating lossis nitriding yuav tsum tau ua rau ntawm qhov chaw nrog kev sib txhuam thiab xov ua ke.
