Yuav ua li cas tuaj yeem ua tau hlau 3D luam kom zoo tshaj plaws qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob?

Cov teeb meem nrog kev ua tau zoo ntawm cov khoom siv hluav taws xob feem ntau yuav tsum ua haujlwm rau cov khoom siv hnyav heev, xws li kub siab, siab corrosion. Piv txwv li, cov cua sov ntawm cov rhaub hauv lub zog hluav taws xob hluav taws xob yog eroded dhau lub sijhawm los ntawm high- kub flue roj. Qhov no tsis tsuas yog kev sim nws tsis kam mus rau siab siab- kub oxidation thiab kev hnav khaub ncaws thiab hnav los ntawm yoov cov nplais hauv cov roj flue. Qhov kev txo qis ntawm qhov kev ua tau zoo ntawm qhov chaw, uas ua rau muaj kev sib pauv cua sov tsis tshua muaj txiaj ntsig thiab ua rau lub neej ntawm cov khoom siv. Hauv kev lag luam petrochemical, cov kev tso tsheb hlau luam thiab cov kev sib pauv cua sov tau raug rau ntau cov ntaub ntawv muaj kev xeb ntau lub sijhawm ntev. Qhov no ua rau lawv cov chaw yooj yim rau corrode, uas tuaj yeem ua rau teeb meem kev nyab xeeb nrog rau kev puas tsuaj ntawm cov khoom siv. Qee cov khoom siv hluav taws xob tseem xav tau cov chaw tshwj xeeb kom ua tau zoo. Piv txwv li, cua tshuab hluav taws xob tuaj yeem xav tau cov chaw uas tsawg hauv kev sib txhuam thiab siab hauv kev hnav tsis kam txiav ntawm cua tsis kam thiab hnav. Tab sis kev tsim cov qauv kev tsim khoom muaj ntau cov teeb meem thaum nws los ua cov qauv ntawm cov txheej txheem saum toj no. Lub tswv yim tom qab hlau 3D luam tawm yog txhawm rau txhim kho cov yam ntxwv ntawm cov chaw. Cov qauv sib tw sib tsoo yog dab tsi ua rau cov hlau 3D luam tau. Nws ua cov ntawv los ntawm cov txheej hlau hlau lossis xaim rau saum ib leeg. Txoj kev no ua rau koj tswj hwm qhov twg thiab yuav ua li cas cov khoom siv tau txais thiab cov qauv yog tsim thaum lub sijhawm ntawv luam ntawv. Qhov no ua rau cov cuab yeej ua haujlwm zoo dua. Piv txwv li, cov tshuab luam ntawv hlau tuaj yeem xaiv cov ntaub ntawv hlau uas ua haujlwm zoo, zoo li siab {19} {{20 {} {tiv taus alloys. Cov ntaub ntawv no yog ruaj khov nyob ruaj khov, tiv taus kev xeb, thiab resistant hnav, uas ua rau nws ua tau txhawm rau txhim kho cov khoom siv saum npoo av. Ntawm qhov tod tes, hloov cov khoom xws li lub zog laser, ntsuas tuab, thiab txheej txheej tuab tuaj yeem tswj hwm lub microstructure ntawm cov khoom, thiab qhov loj ntawm cov nplej thiab theem muaj pes tsawg leeg. Qhov no tuaj yeem hloov pauv cov khoom siv kho tshuab thiab cov khoom siv lub cev. Txoj hauv kev los txhim kho kev ua tau zoo ntawm cov chaw siv cov hlau 3D Printing hloov lub microstructure hloov lub microstructure ntawm qhov chaw hlau 3D tuaj yeem ua rau cov chaw nyuaj micrittructures nrog kev raug. Piv txwv li, microstructures ntawm qee cov ntaub ntawv thiab ntau thiab tsawg, xws li cov tawv nqaij biomimetic surner, tuaj yeem luam tawm ntawm cov cua tawv nqaij tawv nqaij ua kom tawv nqaij tawv nqaij ua kom tawv thiab ntau dua ntawm cov khoom siv hluav taws xob. Qhov no microstructure yuav ua kom sai li cas thaum lub sij hawm luam ntawv, yog li tsis muaj kev xav tau kev ua tiav lawm tom qab. Ntxiv cov microscopic grooves lossis pob rau sab hauv cov roj pipelines tuaj yeem cuam tshuam cov kua dej li cas, thiab ua rau nws txav yooj yim dua. Cov microstructures no kuj tuaj yeem pab txiav kom tsis txhob teev thiab ua kom lub raj xa dej ntev ntev nyob rau tib lub sijhawm. Ua cov ntaub ntawv Gradient Cov sib txawv ntawm qee cov khoom siv hluav taws xob yuav tsum muaj ntau yam sib txawv ntawm qhov chaw. Cov tshuab tsim 3D yuav ua tau cov ntaub ntawv gradient, uas yog cov khoom siv uas muaj cov khoom siv tau sib xyaw lossis cov txiaj ntsig zoo hauv cov cheeb tsam sib txawv ntawm cov laj thawj. Piv txwv li, qhov ntxeev ntawm cov pa roj turbine yuav tsum muaj peev xwm tiv thaiv kom muaj qhov kub thiab hnav, thaum lub hauv paus hniav xav tau kom tiv taus thiab muaj zog. Hlau 3D Luam Ntawv Cia Koj Siv Siab High {37} {} {39} {39} {39} Lub zog, cov khoom siv tawv tawv ntawm lub hauv paus hniav. Qhov no ua rau cov khoom lag luam zoo hloov maj mam, uas txhim kho cov hniav txoj kev ua tau zoo tag nrho thiab kev pabcuam lub neej. Kev kho rau cov txheej saum npoo av thiab kev ua haujlwm koj tseem tuaj yeem siv txheej txheem txheej saum npoo txheej nrog cov khoom siv hlau 3D ntawm cov khoom siv zoo dua. Tom qab luam ntawv ua tiav, ib qho tshwj xeeb kev ua haujlwm tau muab tso rau ntawm lub cuab yeej. Qhov no tuaj yeem yog cov txheej uas tiv thaiv kev kub siab, xeb, lossis kev sib txhuam, piv txwv. Lub cev vapor deposition (PVD), tshuaj vapor deposition (CVD), thiab lwm cov txheej txheem tuaj yeem siv los ua cov txheej no. Lawv lo zoo rau cov hlau 3D luam ntawv sau cov khoom siv. Piv txwv li, tso cov thermal teeb meem txheej ntawm cov hniav ntawm aerospace tshuab tuaj yeem txo qis qhov kub thiab txias dua thiab ua haujlwm rau lub cav zoo dua.
