Qhov kev thov rau kev ua yeeb yam, kev ua tau zoo, thiab cov txheej txheem sib xyaw ua ke hauv Aerospace sector yog txhua hnub loj hlob raws li thev naus laus zis. Thaum lub sij hawm nce ntawm 3D tshuab luam ntawv tau coj radical txhim kho rau cov txheej txheem tsim khoom lag luam Aerospace qee zaum muaj cov kev txwv tsis pub muaj nyob rau hauv cov haujlwm no. Ntawm lawv, kev nce qib ntawm Aerospace 3D tshuab luam ntawv tau ntau yam los ntawm txoj kev kawm thiab kev txhim kho cov hmoov hlau txhim kho.
Kev luam tawm 3D, qee zaum hu ua kev tsim khoom ntxiv, yog cov txheej txheem rau txheej los ntawm txheej txheej ntxiv los tsim peb-seem. 3D luam ntawv tshuab boad dawb boasts zoo dua cov khoom siv, kev tsim qauv nrawm dua li kev tsim kev tsim khoom lossis cov khoom siv sib luag. 3D tshuab luam ntawv tshuab yog qhov siv tau zoo nyob rau hauv ib lub chaw tsim khoom, kev tsim kho cav, thiab chaw tsim khoom dav hlau.
Tshwj xeeb hauv kev lag luam AERPACACE, qhov chaw muaj kev ua tau zoo heev rau kev ua tau zoo ntawm cov hlau hlau, cov hlau tuab yog cov khoom lag luam nyoos rau 3D luam ntawv tshuab. Cov hmoov qib hlau hlau tau thov cov khoom xws li xws li spherability zoo, wangability, haum particle loj faib, thiab siab purity. Cov khoom no ncaj qha rau kev ua tau zoo thiab ua tau zoo ntawm 3D luam tawm cov khoom, yog li kev txhim kho cov hmoov hlau hlau tau dhau los ua kev txhim kho aurooronutical 3D tshuab luam ntawv.
Ob feem ntau siv cov kev npaj npaj nyob rau hauv kev kawm thiab kev txhim kho cov hmoov hlau tsis sib xws Qhov npaj ua ntej tuaj yeem npaj cov hmoov hlau nrog lub ntsej muag siab, cov hmoov av loj, thiab zoo heev ntawm cov khoom lag luam zoo nkauj hauv tshav luam ntawm 3D luam ntawv; Txoj kev Viga muaj cov txiaj ntsig siab ntawm cov hmoov zoo tab sis teeb meem nrog cov hmoov hollow thiab cov hmoov satellite. Kev tsim kho thiab kho tshiab ntawm cov ntshav siab tshiab electrode atomode hmoov tshuab thiab cov khoom siv ntau lawm, yog li kev txhim kho qhov zoo ntawm kev npaj ua kom zoo.
Sib nrug los ntawm kev txhim kho cov txheej txheem npaj, kev ua yeeb yam ntawm cov hmoov hlau yog ntau yam los ntawm nws txoj kev huv. Txog kev siv tshwj xeeb zoo li aerospace, cov neeg siv khoom muaj cov qauv uas muaj tseeb rau cov hlau hmoov huv. Cov ntsiab lus oxygen ntawm titanium alloy hmoov yog {{{}}}}}}}}}}}}}}} 13%; Cov pa roj oxygen cov ntsiab lus siab ntawm cov hmoov kub kom muaj kev tswj hwm tau tswj hwm ntawm 0.006% thiab 0.018%; Thiab cov ntsiab lus oxygen ntawm stainless hlau hmoov yog 0.0% rau 0.025%. Cov kev lees paub nruj kev lav phib lav cov kev lees paub tseem ceeb xws li 3D luam tawm cov khoom, corrosion tsis kam, thiab kev kub ntxhov siab.
Aerospace 3D printing kuj nyob ntawm particle loj faib ntawm cov hlau hlau. sib txawv 3D luam printing cov tswv yim thiab cov qauv duab thov cov hmoov sib txawv sib xws siv cov txheej txheem faib tawm loj. Rau cov luam ntawv 3D, feem ntau siv tau hmoov hmoov particle loj tam sim no ntau yam tam sim no yog 15-150 μ m. Vim tias lawv zoo tsom iav thiab yooj yim melting ntawm hmoov zoo, luam ntawv khiav ntawm cov hmoov av yog qhov tsim nyog rau cov hmoov txhuv nplej siab txij li 15 txog 53 μ m; Tshuab luam ntawv ntiav Electron nqaj muaj cov coarser me me, yog li lawv tau siv hmoov zoo los ntawm 53 txog 105 μ m. Hmoov muaj cov particle loj ntawm 105-150 μ m yuav siv tau rau coaxial hmoov pub luam ntawv luam ntawv.
Ib qho kev txiav txim siab tseem ceeb ntawm cov hmoov hlau flowility yog nws spherericity. Feem ntau hais lus, hmoov patalle flowability yog qhov zoo dua lawv cov sphererity. Txhawm rau lav cov khoom ua kom muaj hmoov nplej thiab pub mis thaum muab khoom siv hlau, 3D luam tawm ntawm cov hlau cov hlau xav tau spherericity ntawm ntau tshaj li 98%. Kev npaj cov txuj ci tseem ceeb rau cov khoom zoo 3D luam tawm cov hmoov hlau hlau yog aerosolization thiab tig cov tswv yim hluav taws xob; Yog li, cov duab hmoov ua los ntawm ob txheej txheem no yog qhov tseem ceeb kheej, ua rau cov qauv siab ntawm 3D luam ntawv.
Sib nrug los ntawm kev nce qib aircraft 3D tshuab luam ntawv tshuab, kev tshawb fawb thiab kev txhim kho cov hmoov hlau tshiab txhawb cov hmoov metallurgy tshuab ua rau cov hmoov metallurgy thev naus laus zis thiab kev txhim kho. Siv cov txuj ci nrog rau nias thiab Sintering cov hmoov av, hmoov metallurgy yog cov khoom siv ua kom zoo dua qub. Aerospace hmoov metallurgy yog qhov ua tau zoo los ua cov kev tsim kho lub teeb thiab cov khoom siv sib txawv. Hmoov metallurgy thev naus laus zis tau tsim ntxiv thiab ua kom zoo dua nrog kev ua haujlwm thev naus laus zis ntawm "3D luam ntawv + hmoov metallurgy".
Ib txheej txheem tshiab ua ke ua ke ua ke 3D luam ntawv thiab hmoov metallurgurgy technologies yog hmoov extrusion luam ntawv (pep). Thawj zaug sib xyaw hlau / tej hmoov nplej nrog cov organic binders los ua pellets, thiab kawg dencing lawv los ntawm sintering los tsim cov khoom siv nrog kev ua tau zoo ib yam thiab ua tau zoo. Sib nrug los ntawm pwm dawb npaj, pep technology nce kev ua tau muaj peev xwm thiab hloov tau yooj yim dua thiab hloov cov kev daws teeb meem ntau dua rau lub tshuab hluav taws xob aerospace.
Cov kev tshawb fawb thiab kev txhim kho cov hmoov av hlau siab tshaj txhawb nqa kev nce qib ntawm Aerospace 3D tshuab luam ntawv tshuab
