Qhov sib txawv hauv kev ua cov nruab nrab ntawm Gr2 polished Titanium hlau thiab Gr2 Titanium Vuam Hlau
Nyob rau hauv high -}} titanium alloy (coj mus ua tus neeg suav, thiab cov tshuaj lom neeg tsis kam, muaj zog, thiab biocompatibility. Txawm li cas los xij, raws li ob daim ntawv tseem ceeb, Gr2 polished titanium hlau thiab Gr2 lub vuam hlau nthuav qhia qhov sib txawv ntawm lawv cov txheej txheem ua haujlwm.
Qhov sib txawv ntawm cov hom phiaj txheej txheem
Cov hom phiaj tseem ceeb ntawm Gr2 polished titanium hlau yog txhawm rau txhim kho qhov chaw zoo los ntawm kev tshem tawm cov discers thiab khawb kom ua tiav ib daim iav {}} zoo li ua tiav. Qhov no ua tau raws li txoj hlua khi xeb tsis kam thiab biocompatibility Piv txwv li, hauv daim cardiovascular stent manufacturing, qhov chaw saum npoo ntawm polished titanium hlau yuav tsum tau tswj hwm rau RA tsawg dua lossis sib npaug rau 0.05μm kom txo qis kev pheej hmoo ntawm thrombosis.
Cov txheej txheem lub hom phiaj rau Gr2 Titanium Vuam hlau tsom rau kev ua kom zoo dua vuam kev ua tau zoo. Los ntawm kev tswj hwm kev tswj hwm thiab kev kho deg, cov khoom siv me me ntawm cov hlau weld tau sib phim rau cov khoom siv hauv paus, thaum tseem tsis taus xws li weld tawg thiab porosity. Piv txwv li, hauv lub dav hlau tshuab kho kom zoo dua li ntawm cov khoom siv vuam ntau dua lossis sib npaug rau ntawm 15%, thiab cov khoom siv hydrogen hauv Weld cheeb tsam yuav tsum tsawg dua 0.005%.
Core txheej txheem sib piv
GR2 polished titanium hlau
Neeg kho tshuab Pretreature: ntxhib Polishing nrog pob zeb diamond abrasives tshem tawm cov txheej oxide thiab machining cov cim. Nruab nrab polishing nrog cubic boron nitride (cbn) abrasives tshem tawm cov khawb sab laug los ntawm ntxhib polishing. Piv txwv li, chaw kho mob rau cov chaw tsim tshuaj xees siv cov txheej txheem tawv nqaij thiab cov tawv ntoo sib xyaw ua ke nrog kev siv hluav taws xob sib xyaw ntawm RA 3.2μm rau RA 0.8μm.
Kev siv roj electrolytic: siv hydrofluoric acid (HF) raws li kev txhim kho hluav taws xob (50v) Piv txwv li, kev kawm kom tsim nyog rau cov qauv siv electrolyte (90 mL chanchi}}}
Tshuaj lom neeg polishing: rau cov txheej txheem nyuaj (xws li titanium alloy flolof [}} hydroflluoric acid sib xyaw yog siv rau kev siv tshuaj polishing. Zuag qhia tag nrho cov homogenization tau tiav los ntawm kev tswj qhov kub (60 degree) thiab sijhawm (3 feeb).
GR2 Titanium Vuam Hlau
Kev Tsim Tsim Tsim: Los kho cov kev sib piv ntawm cov ntsiab xws li titanium, txhuas, thiab vanadium kev hloov pauv ntawm weld hlau tau zoo. Piv txwv li, usei {- 2 vuam hlau (muaj 0.03% n, thiab 0.3% Fe) yog tsim rau vuam hlau (TI-6AL-4V) yog siv rau Vuam Titanium alloys. Nws cov ntsiab lus txhuas txhim kho lub zog siab-kub ntawm lub weld. Kev tu npoo npoo: Ulte tshem cov roj tsis taus roj, tom qab los ntawm pickling (10% hom) kom tshem cov oxide txheej. Thaum kawg, ntshiab argon (ntau dua los yog sib npaug rau 99.99%) Kev Tiv Thaiv yog siv los tiv thaiv kev nkag los ntawm hydrogen, oxygen, thiab nitrogen thaum vuam. Piv txwv li, hauv cov khoom siv vuam, qhov chaw huv si ntawm lub vuam hlau yuav tsum ntsib ISO 8501-1 SA 2.5 kom paub meej tias yog Weld dawb.
Cov ntsiab lus tseem ceeb ntsuas: Qhov kev tsis sib haum xeeb ntawm precision thiab ruaj khov
GR2 polished titanium hlau
Electrolytic yuav tsum tau tswj hwm yuav tsum tau tswj hwm hauv ± 1V, thiab cov hluav taws xob hluav taws xob yuav tsum ruaj khov ntawm 25 ± 2 degree. Yog tsis ua li ntawd yuav ua rau muaj kev ua txhaum loj heev lossis tsis txaus ntseeg. Piv txwv li, ib lub tuam txhab qhia txog cov kab pid kub thiab hloov kho cov khoom siv electrolyte los ntawm 85% mus rau 98%. Neeg kho tshuab polishing tsis: lub polishing lub log ceev yuav tsum tau kho raws li lub taub titanium hlau. Ib tug 1mm lub inch titanium hlau yuav tsum muaj kev sib zog tsawg ntawm 900-1200 rpm kom tsis txhob muaj cov npoo hluav taws xob; Ib tug 5mm inch titanium hlau tuaj yeem ua polished ntawm qhov kev kub ceev ntawm 1500-1800 rpm rau kev txhim kho kev ua tau zoo.
GR2 Titanium Vuam Hlau
Vuam cov kev tswj tam sim no: hauv roj tungsten arc vuam (gtaw), 2.05} Khis} 2 pev yuav tsum tau ua lub thawv weld ruaj khov. Piv txwv li, hauv cov aviation raj vuam, kev saib xyuas tiag tiag ntawm ± 0.5v) tuaj yeem tswj hwm WELD Tsim ntawm 1.2 thiab 1.5, tiv thaiv kab nrib pleb.
Kev thaiv cov roj ntws: tus nqi txaus siab ntawm 16 -}} Txoj kev hood los tiv thaiv qab hood los tiv thaiv qhov chaw siab. Piv txwv li, lub tuam txhab marine encessing kho kom txo cov ntsiab lus weld oxygen cov ntsiab lus los ntawm 200ppm mus rau hauv qab 50ppm, peb npaug weld corrosion tsis kam.
Kev xaiv cov khoom sib txawv: los ntawm standalone rau kev ua hauj lwm ua haujlwm tshiab
Gr2 polished titanium hlau feem ntau ntawm cov khoom siv standalone, suav nrog cov tshuab hluav taws xob elecololyers, cov tshuab siv kho txhua yam, thiab cov tshuaj tua hluav taws xob. Thaum cov peev txheej kev nqis peev yog tsawg heev, nws tso siab rau cov neeg teb tsav tsheb. Piv txwv li, kho mob lub tuam txhab ntaus hlau siv ib qho kev kuaj xyuas lub sijhawm los saib xyuas cov kev kuaj xyuas polished hauv lub sijhawm, nce kev tswj kev sib xws los ntawm tsibfold.
Gr2 titanium vuam hlau, nyob rau ntawm qhov tod tes, yuav tsum muaj cov khoom siv vuam, thiab cov xaim hluav taws xob, ua rau muaj cov khoom lag luam lag luam muaj peev xwm. Piv txwv li, hauv lub dav hlau cav vuam, laser {}}}} pa taws vuam ntawm 0.5mm nyias cov xov hlau, ua tiav Weld lub zog ntau npaum li 95% ntawm niam txiv hlau.
Qhov sib txawv hauv kev ua ntawm gr2 polished titanium hlau thiab Gr2 titanium vuam hlau yog qhov tseem ceeb ntawm kev sib koom ua ke ntawm cov kev ua haujlwm sib txawv thiab kev ua haujlwm loj. Cov txheej txheem polishing txhim kho kev ua tau zoo saum npoo los ntawm micro - morphology tswj, thaum lub vuam txheej txheem sib txuam thiab kev tswj kom sov.
