Nyob rau xyoo 1980, kev txhim kho sai ntawm kev lag luam semiconductor tau muab cov kev xav tau siab dua rau kev tu tshuab ntawm cov kab mob sib kis ntawm lub ntsej muag ntawm silicon wafer qhov ncauj qhov ntswg. Lub ntsiab lus tseem ceeb yog kom kov yeej lub zog adsorption zoo ntawm cov kab mob thiab cov substrate. Kev tu tshuaj ib txwm siv, kev tu txhua yam, thiab kev tu ultrasonic tsis tuaj yeem ua tau raws li cov kev xav tau, thaum lub laser tu tuaj yeem daws cov teeb meem muaj kuab paug, thiab lwm yam kev tshawb fawb thiab kev siv tau tsim sai heev. Xyoo 1987, muaj thawj daim ntawv thov patent rau laser tu.
Tom qab nkag mus rau xyoo 1990, Zapka et al. ntse siv laser tu tshuab rau semiconductor manufacturing txheej txheem, tshem tawm microparticles ntawm lub npog ntsej muag, thiab ua tiav daim ntawv thov thaum ntxov ntawm laser tu tshuab nyob rau hauv industrial teb. Xyoo 1995, cov kws tshawb fawb tau ua tiav kev tu lub dav hlau fuselage xim siv 2kW TEA-CO2 laser. Tom qab nkag mus rau lub xyoo pua 21st, nrog rau kev loj hlob sai ntawm Ultrashort mem tes lasers, kev tshawb fawb thiab kev siv cov tshuab ntxuav laser hauv tsev thiab txawv teb chaws tau maj mam nce, tsom mus rau kev tu cov khoom siv hlau. Cov ntawv thov txawv teb chaws suav nrog kev tshem tawm lub dav hlau lub cev, tshem tawm cov pwm ntawm cov roj stain, lub cav sab hauv cov pa roj carbon deposition tshem tawm thiab kev sib koom ua ke ntawm qhov chaw ntxuav ua ntej vuam.
Hlau yog dav siv nyob rau hauv kev lag luam, xws li tsheb welding, shipbuilding, painting, thiab turbine hniav manufacturing. Laser tu tshuab tuaj yeem tshem tawm xeb, xim, thiab av los ntawm qhov chaw ntawm cov khoom hlau, yog li ua kom cov vuam zoo thiab cov nyhuv pleev xim. Laser tu tshuab tau siv los ntxuav lub npoo ntawm marine carbon steel daim hlau ua ntej vuam. Cov txiaj ntsig kev tshawb fawb tau pom tias kev ua haujlwm ceev ntawm laser tu tuaj yeem nce mus rau 1000mm / min los ntawm kev nce lub zog nruab nrab lossis nce lub teeb ci laser. Lub tshuab ntawm laser ablation muaj xws li lub cev thiab tshuaj lom neeg cov teebmeem thiab elastic vibration teebmeem.
Nrog rau qhov sib txawv laser zog ceev, ob qhov cuam tshuam muaj qhov sib txawv ntawm kev cuam tshuam ntawm kev ntxuav lub tshuab. Txoj cai damping oscillation propagation law ntawm laser induced plasma shock yoj hauv cov ntaub ntawv tau pom, thiab ib qho kev soj ntsuam online rau cov txheej txheem ntxuav laser tau tsim. Kev sib raug zoo ntawm oxide tshem tawm degree, plasma luminous siv, thiab lub suab yoj ntev tau tsim. Ntxiv nrog rau kev tshem tawm cov xeb tag nrho, laser kuj tuaj yeem tsim cov txheej txheej nyias nyias ntawm lub substrate. Cov txheej txheej hardening tuaj yeem txhim kho qhov hardness ntawm carbon steel nto, ua lub luag haujlwm ntxiv dag zog rau saum npoo, thiab qee qhov tiv thaiv cov pa roj carbon steel.
Laser tu tshuab tsis tau tsuas yog siv rau saum npoo ntawm txhuas alloy ua ntej welding, tab sis kuj mus rau saum npoo kev kho mob ua ntej aluminium alloy bonding. Cov kev tshawb fawb zoo sib xws tau muab piv rau cov txiaj ntsig ntawm kev kho cov ntshav plasma qis thiab laser ntxuav ntawm lub zog shear ntawm cov nplaum nplaum. Cov txiaj ntsig tau pom tias qhov nruab nrab shear lub zog ntawm cov qauv ntxuav laser yog 19.35MPa, uas yog kwv yees li 5MPa siab dua li kev kho ntshav ntshav.
Thaum lub laser tu, nws yog ib qho tsim nyog los xaiv qhov tsim nyog tsis xws li laser wavelength, mem tes dav, thiab mem tes zaus raws li cov khoom siv sib txawv. Feem ntau ntawm kev tshawb fawb hauv tsev thiab txawv teb chaws ntawm laser ntxuav cov txheej thiab cov khoom me me tau xaiv nanosecond pulse fiber ntau lasers nrog lub wavelength ntawm 1064nm. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb hauv laser pulse zaus ntawm ob. Lub qub muaj ib tug mem tes zaus ntawm ob peb txhiab mus rau ob peb kaum ntawm kilohertz, thiab lub nto roughness tom qab ntxuav yuav ncav cuag 1 μ Lub tom kawg yog concentrated nyob rau hauv ntau ntawm ob peb hertz mus rau ob peb kaum ntawm hertz, nrog rau kev tshem tawm ntawm ntau tshaj 90 feem pua. .
Cov kws tshawb fawb hauv tsev tau ua kev tshawb fawb hauv thaj chaw ntawm kev tu lub laser kuj lig, ua ke nrog cov nqi siab ntawm luv luv mem tes lasers lawv tus kheej, uas yuav tsum tau ua kom zoo dua tu kom ua tiav cov txiaj ntsig zoo hauv kev siv tswv yim. Yog li, tam sim no muaj tsawg heev cov ntawv thov cuam tshuam. Nyob rau hauv xyoo tas los no, qee lub tsev kawm ntawv qib siab, cov koom haum tshawb fawb, thiab cov tuam txhab lag luam hauv Suav teb tau ua tiav kev tshawb fawb ntawm kev siv laser tu tshuab hauv kev lag luam, thiab tseem tau tsim cov khoom siv laser tu.
Tuam Tshoj Academy ntawm Engineering Physics tau ua kev tshawb fawb txog kev tshem tawm cov pwm tso tawm cov neeg ua haujlwm rau cov log tsheb pwm, xim tshem tawm cov dav hlau tis thiab radomes (cov ntaub ntawv sib xyaw) thiab lub tank armor, thiab xeb tshem tawm cov khoom hauv hiav txwv. Suzhou University tau tshawb fawb txog kev tshem tawm xeb ntawm tsheb volutes, taug qab kev saib xyuas thiab tshem tawm cov av, thiab tshem tawm cov nplais ntawm insulating cov fwj porcelain.
Cov saum toj no qhia txog cov kev tshawb fawb tam sim no ntawm laser tu hauv tsev thiab txawv teb chaws. Nyob rau hauv cov nqe lus ntawm txoj kev xav thiab technology, txawm hais tias ib tug loj tus naj npawb ntawm thwmsim tau ua nyob rau hauv cov txheej txheem kev tshawb fawb ntawm laser ntxuav ob lub teb chaws thiab txawv teb chaws, txoj kev tshawb xav thiab mechanism ntawm kev tshawb fawb ntawm laser tu yog tseem tsis tiav. Txawm hais tias cov qauv tsim muaj feem xyuam rau lub cev, cov qauv no tseem muaj cov kev txwv tseem ceeb. Hais txog kev siv tswv yim, muaj qhov sib txawv tseem ceeb ntawm Tuam Tshoj thiab txawv teb chaws.
