Cov ntawv thov ntawm Lasers hauv kev lag luam
Kev Taw Qhia: Txij li thaum nws tshwm sim hauv xyoo 1960, cov thev naus laus zis laser tau hloov pauv sai sai mus rau hauv cov cuab yeej tseem ceeb hauv kev tsim khoom lag luam, ua tsaug rau nws lub zog ceev ceev, kev coj ua zoo heev thiab kev tswj tau. Piv nrog rau cov txheej txheem ua khoom siv ib txwm muaj, kev ua laser muaj cov txiaj ntsig sib txawv xws li kev ua haujlwm tsis sib cuag, kev ua haujlwm siab thiab kev ua haujlwm siab, thiab tau siv dav hauv cov txheej txheem tsim khoom lag luam suav nrog kev txiav cov khoom siv, vuam, cim, khawb thiab kev tsim khoom ntxiv. Raws li hom laser thiab lawv cov yam ntxwv ntawm cov txheej txheem, kev ua laser kev lag luam feem ntau yog muab faib ua peb hom: txiav laser, vuam laser thiab kev tsim khoom ntxiv laser, txhua tus muaj cov txheej txheem ua haujlwm tshwj xeeb thiab cov ntawv thov.
Kev Txiav Laser
Kev txiav laser yog ib qho ntawm cov kev siv laser hauv kev lag luam uas laus tshaj plaws. Nws siv cov teeb laser muaj zog heev los yaj thiab ua pa cov khoom, thiab koom tes nrog cov pa roj pab kom tshuab cov slag uas yaj tawm, ua tiav kev txiav zoo thiab raug. Tam sim no, CO₂ lasers thiab fiber lasers yog cov khoom siv tseem ceeb, tsim nyog rau kev txiav cov phaj nruab nrab thiab nyias ntawm cov hlau carbon, hlau tsis xeb, txhuas alloy thiab lwm yam khoom siv. Cov thev naus laus zis no yog tus cwj pwm los ntawm kerf nqaim, thaj chaw cuam tshuam los ntawm cua sov me me, tsis tas yuav pwm thiab hloov pauv sai ntawm cov txheej txheem ua, ua rau nws siv tau tshwj xeeb rau cov lag luam xav tau siab xws li kev tsim tsheb, kev ua cov hlau ntawv thiab aerospace.
(1) Hauv kev tsim tsheb, kev txiav laser yog siv los tsim ntau yam khoom xws li cov vaj huam sib luag ntawm lub cev mus rau lub cav. Piv txwv li, cov laser fiber raug saws rau kev txiav cov khoom siv hlau muaj zog siab, yog li ua kom pom qhov tsim ntawm lub tsheb sib dua.
(2) Kev lag luam aerospace kuj tau txais txiaj ntsig los ntawm kev siv tshuab laser txiav, tshwj xeeb tshaj yog hauv kev tsim cov khoom sib xyaw ua los ntawm cov khoom siv siab heev xws li titanium thiab cov khoom sib xyaw. Piv txwv li, cov lasers ceev ceev tuaj yeem siv los txiav cov khoom sib xyaw titanium alloy uas muaj cov duab sib xyaw thaum txo qis kev puas tsuaj thermal, ua kom ntseeg tau tias cov qauv ntawm cov khoom thiab txhim kho kev ua tau zoo thiab kev nyab xeeb ntawm cov khoom aerospace.
Kev vuam laser
Kev vuam laser ua tiav kev sib koom ua ke ntawm cov khoom siv los ntawm kev siv cov teeb laser los yaj cov khoom siv hlau sai sai, muaj qhov nkag mus tob, ceev ceev thiab qis cua sov. Cov hom vuam feem ntau suav nrog kev vuam laser tas mus li thiab kev vuam laser pulsed, uas tsim nyog rau kev vuam meej ntawm cov phaj nyias thiab cov xwm txheej vuam nkag mus tob. Piv nrog kev vuam arc, kev vuam laser tsim cov vuam nrog lub zog siab thiab tsawg deformation, thiab siv tau rau cov teb xws li kev ntim roj teeb fais fab, kev vuam cov khoom tsis xeb thiab kev tsim khoom siv hluav taws xob nuclear. Tshwj xeeb hauv kev tsim roj teeb, kev vuam laser tau dhau los ua txoj kev sib txuas tseem ceeb.
(1) Hauv kev lag luam tsheb, kev vuam laser yog siv los koom nrog cov vaj huam sib luag ntawm lub cev, cov khoom siv cav thiab lwm yam khoom tseem ceeb. Piv txwv li, cov laser fiber yog siv rau kev vuam qhov tseeb ntawm cov khoom siv hlau muaj zog, tsim cov pob qij txha ruaj khov thiab ruaj khov.
(2) Hauv kev lag luam hluav taws xob, kev vuam laser yog siv rau kev sib txuas siab ntawm cov khoom me me thiab cov khoom me me. Piv txwv li, diode lasers yog siv los vuam cov roj teeb hauv cov roj teeb lithium-ion, kom ntseeg tau tias muaj kev ntseeg siab ntawm kev sib txuas hluav taws xob.
(3) Hauv kev lag luam aerospace, Boeing 787 Dreamliner siv cov thev naus laus zis laser vuam los koom nrog cov hlau titanium thiab cov ntaub ntawv sib xyaw, uas txo cov lej ntawm cov rivets, txo qhov hnyav ntawm lub fuselage thiab txhim kho kev siv roj.
Kev Tsim Khoom Siv Laser Additive
Kev tsim khoom siv laser ntxiv (piv txwv li laser 3D luam ntawv) ua tiav cov txheej txheem tso tawm ntawm cov qauv nyuaj los ntawm kev yaj cov hmoov lossis cov ntaub ntawv hlau txheej los ntawm txheej, sawv cev rau kev hloov pauv ntawm cov txheej txheem tsim khoom los ntawm "kev tsim khoom rho tawm" mus rau "kev tsim khoom ntxiv".Cov txheej txheem tsim khoom siv laser, xws li kev xaiv laser melting (SLM) thiab kev tso hlau ncaj qha (DMD), muaj peev xwm tsim cov khoom siv hlau nyuaj nrog qhov tseeb siab thiab lub zog siab. Piv nrog rau kev ua cov txheej txheem ib txwm muaj, kev tsim khoom siv laser ntxiv tuaj yeem ua tiav kev sib xyaw ua ke thiab kev tsim qauv sib dua ntawm cov qauv nyuaj thaum tswj cov khoom siv lub zog.
(1) Hauv kev tsim tsheb, cov khoom sib xyaw titanium alloy ntawm Ferrari F1 tsheb sib tw yog tsim los ntawm kev siv tshuab laser additive manufacturing, uas ua rau muaj kev tiv thaiv cua sov thiab lub zog ntawm cov khoom thiab ua kom zoo dua qhov kev tsim qauv aerodynamic ntawm cov tsheb sib tw.
(2) Hauv kev lag luam kho mob, kev tsim khoom siv laser yog siv los tsim cov khoom cog thiab cov khoom cuav.
(3) Hauv kev lag luam aerospace, kev tsim khoom siv laser ntxiv rau kev tsim cov khoom sib xyaw xws li cov hniav turbine thiab cov roj nozzles.
