Yuav ua li cas txiav txim siab qhov zoo ntawm titanium rods?
Hauv kev tsim khoom siab -kawg kev lag luam xws li aerospace, cov cuab yeej kho mob, thiab kev lag luam hauv hiav txwv, titanium rods yog cov khoom siv tseem ceeb, thiab lawv qhov zoo ncaj qha txiav txim siab txog kev ua haujlwm thiab kev nyab xeeb ntawm cov khoom. Los ntawm domestically tsim lub dav hlau loj cav hniav mus rau cov khoom siv cog qoob loo, kev sib xyaw ua ke, kev ruaj ntseg, thiab kev ncaj ncees ntawm titanium rods yuav tsum ua raws li cov qauv nruj. Txawm li cas los xij, qee qhov qis - tus nqi titanium rods ntawm lub khw muaj teeb meem xws li cov khoom sib xyaw ntau dhau thiab cov qauv tsis xws luag, ua rau cov khoom siv luv luv thiab txawm tias muaj kev nyab xeeb. Mastering scientific identification txoj kev tau dhau los ua txoj haujlwm tseem ceeb rau cov neeg yuav khoom kom muaj kev nyab xeeb ntau lawm.
Cov tshuaj muaj pes tsawg leeg yog qhov taw qhia yooj yim rau kev txiav txim siab zoo ntawm titanium rods. High-cov titanium rods zoo yuav tsum nruj me ntsis ua raws li tus qauv GB/T 3620.1. Noj TC4 titanium alloy ua piv txwv, nws cov ntsiab lus txhuas (Al) yuav tsum tau tswj nyob rau hauv thaj tsam ntawm 5.5% ~ 6.75%, thiab nws cov ntsiab lus vanadium (V) nyob rau hauv thaj tsam ntawm 3.5% ~ 4.5%. Ib lub tuam txhab tsim hluav taws xob aerospace ib zaug tau ntsib kev tawg ntawm cov hniav ntawm lub cav nyob rau hauv siab - qhov kub thiab txias vim kev yuav cov titanium rods nrog ntau cov ntsiab lus txhuas. Thaum lub sijhawm kuaj, kev tshuaj xyuas sai tuaj yeem ua tau siv lub spectrometer, tsom mus rau kev kuaj xyuas ntau dhau ntawm cov impurities xws li hlau (Fe) thiab carbon (C). Cov ntsiab lus hlau ntau dua 0.3% txo qis kev tiv thaiv corrosion, thaum cov ntsiab lus carbon siab tshaj 0.08% yooj yim ua rau intergranular corrosion. Rau kev kho mob- qib titanium rods, cov ntsiab lus ntawm cov khoom sib txuas xws li hydrogen (H) thiab oxygen (O) kuj yuav tsum tau sim. Hydrogen cov ntsiab lus siab tshaj 0.015% tuaj yeem ua rau hydrogen embrittlement, ncaj qha hem kev nyab xeeb ntawm cog.
Kev soj ntsuam cov qauv tuaj yeem qhia qhov zoo ntawm cov titanium rods. High-cov titanium rods zoo yuav tsum muaj qhov sib xws + dual- theem qauv, nrog cov nplej loj tswj hauv 5-8 qib (ASTM E112 tus qauv). Hauv qhov sib sib zog nqus-kev tshawb nrhiav dej hiav txwv, kev ntxhov siab corrosion tawg tau tshwm sim nyob rau hauv kev kub ntxhov vim yog siab dhau - theem feem (tshaj 40%) hauv titanium rods. Thaum lub sij hawm sim, grain morphology tuaj yeem pom tau siv lub tshuab ntsuas metallographic, lossis cov theem muaj pes tsawg leeg tuaj yeem txheeb xyuas siv X-ray diffraction. Rau qhov txias- ua haujlwm titanium pas nrig, nws yog ib qho tsim nyog yuav tsum tau kuaj xyuas cov kab ua haujlwm tsis zoo lossis cov qauv tsim, vim tias cov teeb meem no txo qis cov khoom isotropic ntawm cov khoom. Cov kab ntawm cov txheej txheem kho cua sov yog qhov tseem ceeb sib npaug. Kev daws teeb meem titanium rods yuav tsum pom cov khoom sib xws, thaum quenching cov kab nrib pleb los yog overheated / hlawv cov qauv yuav tsum tsis txhob nruj me ntsis.
Qhov saum npoo zoo thiab qhov tseeb qhov tseeb ncaj qha cuam tshuam rau kev ua haujlwm ntawm titanium rods. High-cov titanium rods zoo yuav tsum muaj cov xim hlau zoo sib xws, tsis muaj qhov tsis xws luag xws li tawg, folds, thiab oxide nplai. Qee qhov chaw tsim khoom siv tsheb tau ntsib cov khoom tawg thaum lub sijhawm forging vim yog siv cov titanium rods nrog microcracks ntawm lawv qhov chaw. Thaum lub sij hawm soj ntsuam, 10x magnifying iav tuaj yeem siv los soj ntsuam qhov xwm txheej ntawm qhov chaw, lossis kev ntsuas kev nkag siab (PT) thev naus laus zis tuaj yeem siv los kuaj xyuas cov teeb meem hauv feeb. Hais txog qhov tseeb ntawm qhov loj me, nws yog qhov tsim nyog los xyuas kom meej tias txoj kab uas hla, roundness, thiab straightness ua tau raws li qhov yuav tsum tau ua. Piv txwv li, txoj kab uas hla ntawm titanium rods siv rau kev kho mob cog yuav tsum tau tswj nyob rau hauv ± 0.02 hli. Rau titanium rods xav tau kev siv tshuab ntxiv, qhov kawg ntawm lub ntsej muag bevel (feem ntau Tsawg dua los yog sib npaug rau 0.5mm) thiab nto roughness (Ra Tsawg dua lossis sib npaug li 1.6μm) kuj yuav tsum tau kuaj xyuas. Cov kev ntsuas no ncaj qha cuam tshuam rau machining efficiency thiab tawm los.
Los ntawm kev soj ntsuam nruj me ntsis ntawm cov tshuaj muaj pes tsawg leeg mus rau kev soj ntsuam xyuas ntawm microstructure, los ntawm kev tshuaj xyuas qhov pom ntawm qhov chaw zoo mus rau qhov ntsuas qhov ntsuas qhov tseeb ntawm qhov tseeb, qhov kev ntsuam xyuas zoo ntawm titanium rods yuav tsum muaj ntau- qhov ntsuas qhov ntsuas. Tawm tsam keeb kwm yav dhau los ntawm kev nce siab sai ntawm kev tsim khoom hauv tsev siab - kawg kev tsim khoom, xaiv cov neeg xa khoom nrog qhov kawg - mus rau - qhov kawg tswj kev muaj peev xwm tau dhau los ua qhov tseem ceeb rau txoj haujlwm ua tiav. Shaanxi Haibowell Hlau Materials Technology Co., Ltd. tau koom tes nrog titanium alloy teb rau ntau tshaj kaum xyoo. Nws cov titanium rods yog ISO 13485 cov txheej txheem kho mob tau lees paub, thiab lawv cov tshuaj muaj pes tsawg leeg, microstructure, thiab nto zoo tag nrho mus txog qib siab thoob ntiaj teb, muab cov khoom siv txhim khu kev qha rau kev lag luam xws li aerospace thiab cov cuab yeej kho mob.
